About Us Our mission is to electrify the world’s homes for healthy and sustainable living. Residential electrification is an extraordinary decarbonization opportunity - 145 million homes in the United States account for 20% of our climate emissions. But today electrification is painful - it’s too complicated, time consuming, and expensive. So we’re building a new experience for homeowners, contractors, and utilities. Zero bridges the gap between the digital and the physical with a frictionless experience that makes electrification fast, easy, and affordable. Join our team to build a world class consumer experience that just so happens to electrify America. About the Role & Your Impact This is an exciting opportunity for those with 1-5 years of professional experience to join an early stage company of talented engineers and designers, led by seasoned climate tech veterans. We are looking for candidates with outstanding potential and serious work ethic. If you want to spend the next 5 years of your career learning and growing faster than you can imagine, and you are eager to put in the long hours necessary, Zero is the place for you. Junior Engineers work in small teams (1 designer and 1-2 programmers) in six-week cycles to take well defined projects and improve existing features. You will be given ample access to coaching, mentoring, and collaboration across the team, but will also be expected to operate effectively with minimal oversight. We are relentlessly focused on sustainable productivity. You should expect long stretches of deep work, no standing meetings, effective in person collaboration with stakeholders and peers, as well as flexibility around your personal life. The products we build serve a diverse range of customers: homeowners, contractors, and utilities, as well as the Zero employees that support these customers. Examples include a CAD application that designs HVAC and energy efficiency projects, our soon to be launched website refresh, and web apps that allow contractors and utilities to review and approve jobs. These products are built using Nuxt, Typescript & Tailwind, but no one on our team had experience with that complete stack before joining, and we don’t expect you to either. No matter what product you are working on, the code you write will be directly responsible for deploying millions of dollars into safer, healthier, and more cost-effective homes. What You Bring You want to do big things, and you want to join a team that will teach you how. You are ambitious, hard working, and hungry for growth. You have high standards for yourself, and your team. You are relentless in the face of challenges, and recognize that the only path to excellence is through failure. You are a detail-oriented systems thinker. You want to learn how to own the whole product, not just isolated features. You always anchor your work on user needs and seek to understand how users operate in a larger context. You may not have experience in climate tech or building science, but you are eager to dive into the messy world of residential electrification. You have an eye for elegance - the confluence of beauty, effectiveness, and simplicity - and there are early signs that you can build elegant digital experiences from the ground up. You value functional beauty in the physical world, and you are excited to build software that will create healthy, comfortable, and sustainable living spaces for our customers. You are a pragmatic team player. You know that products only matter if they ship, and are an effective collaborator with product designers and senior engineers. You want lots of freedom, but you know that comes with the responsibility to communicate and deliver. You are humble, kind and coachable. You are enthusiastic about in-person work. You want to know your users by name, meet them in person, and you want to see them smile when they use your designs. You live within 50 miles of Denver, CO or are willing to relocate. Nice To Haves - Experience vibe coding and/or using agents - Experience building native mobile applications - Experience at early-stage startups and/or fast-growing environments - Strong math background or practical data science experience - Experience in climate tech

About Charles River Associates Charles River Associates is a leading global consulting firm that provides economic, financial, and business management expertise to major law firms, corporations and governments around the world. CRA advises clients on economic and financial matters pertaining to litigation and regulatory proceedings, and guides corporations through critical business strategy and performance-related issues. Since 1965, clients have engaged CRA for its combination of industry experience and rigorous, fact-based analysis that provide clients with clear, implementable solutions to complex business concerns. Position Overview Charles River Associates is seeking a Full Stack Agentic Developer to help build and evolve a web-based AI platform that enables experts to translate domain expertise into scalable, validated AI-driven workflows. This is a senior full stack engineering role for someone who began with strong product and platform skills and has advanced into LLM-powered agentic systems. The product combines a React/Vite web client, a Node.js/TypeScript backend proxy, Azure-hosted services, and isolated remote execution environments where AI agents run tools against sandboxed project workspaces. This role bridges the application layer and the agent layer: user experience, APIs, session and file workflows, real-time streaming, custom agent runtime behavior, proprietary tools, model-provider integrations, prompt and context systems, reliability, and observability. The ideal candidate is not a narrow frontend engineer, not a pure backend engineer, and not a prompt-only AI specialist. CRA needs a hands-on full stack developer who can design excellent product experiences, write production-grade TypeScript and React, extend Node.js/Express APIs, and also understand how agentic systems plan, use tools, recover from errors, stream activity, and produce work that users can inspect and trust. Core Mission The Full Stack Agentic Developer will own the path from user intent to agent action to reviewed output. This person will build the product workflows and underlying agentic capabilities that let consultants and domain experts create sessions, upload and organize materials, launch AI-assisted work, monitor agent activity in real time, review files and intermediate outputs, and rely on the platform for high-quality analytical work in confidential, high-stakes environments. Key Responsibilities Full Stack Product Development Build and evolve the React web application across core product surfaces: authentication, session setup, workspace navigation, file review, streaming agent activity, results review, and user-facing administration. Create reusable component patterns for complex, stateful workflows while keeping the application maintainable, accessible, and easy for the team to extend. Build and maintain Express/TypeScript API endpoints that support the web application, including session orchestration, file management, workspace operations, usage tracking, and new product capabilities. Integrate frontend workflows with backend services for authentication, LLM routing, usage tracking, agent orchestration, cloud storage, and PostgreSQL-backed application data. Translate complex backend and agent states into intuitive interface patterns, including empty states, progress states, error states, review states, and resumable workflows. Real-Time Agent Experience Implement and improve the real-time streaming interface between the backend, agent runtime, and UI, primarily through server-sent events and related event-driven patterns. Render incremental agent output such as token-by-token text, tool execution cards, plans, task lists, progress indicators, cost and usage indicators, file changes, warnings, and final workflow states. Manage stream connection lifecycle, retries, cancellation, cooperative stop, stop/resume behavior, error recovery, and clear feedback when long-running agent workflows are in progress. Help define event contracts so the UI can present agent behavior clearly without exposing unnecessary implementation complexity to end users. Design UX and API patterns that help users understand what the agent is doing, what files it has changed, what outputs are ready for review, and what still requires human judgment. Agentic Runtime and Tooling Own and improve parts of the custom multi-turn agent loop where the agent sends messages to model providers, parses streaming responses, executes tools, observes results, and iterates within an isolated cloud container. Develop proprietary tools that expand agent capabilities across file operations, analysis, transformation, visualization, document creation, data processing, validation, and workflow automation. Extend the containerized execution environment to support new languages, libraries, utilities, file types, analytical methods, and integrations needed by expert users. Design clear tool schemas, permission boundaries, workspace access patterns, input validation, and error messages that help agents use tools effectively and safely. Create reusable patterns for adding new tools so agent capabilities can expand without making the runtime brittle, opaque, or hard to debug. LLM Provider, Prompt, and Context Systems Support multi-model integration across OpenAI, Anthropic, and other frontier or local models, including provider-specific message formats, tool-calling formats, streaming behavior, structured outputs, and error patterns. Build and maintain translation layers that normalize provider differences while preserving access to the strongest capabilities of each model. Design and maintain prompt and context systems that shape agent behavior, including analytical identity, methodology compliance, interaction modes, tool usage policies, quality standards, and escalation patterns. Implement token estimation, usage tracking, context compression, conversation summarization, prompt caching, and model-selection patterns for long-running analytical sessions. Evaluate how agent behavior changes across providers, model families, prompts, tools, and workflows, then adapt the product and runtime to improve quality, cost, speed, reliability, privacy, and user trust. Session, File, and Workspace Lifecycle Own the user-facing lifecycle of an AI work session, including creation, configuration, file upload, streaming execution, interruption, resumption, result review, workspace cleanup, and teardown. Implement browser-to-cloud file flows including multi-file upload, progress tracking, validation, workspace browsing, previewing, downloading, and handling of large or mixed file types. Support interfaces and APIs that help users understand the state of remote workspaces, generated outputs, intermediate artifacts, source files, and final deliverables. Improve the connection between workspace state and agent state so users can review work product clearly and engineers can debug session behavior reliably. Reliability, Security, and Observability Implement reliability patterns such as retry logic, rate-limit handling, tool error recovery, cooperative stop, graceful cancellation, resumability, and failure reporting. Build with enterprise readiness in mind, including secure browser authentication flows, JWT lifecycle, role-based access, CORS, CSRF considerations, auditability, privacy-sensitive UI patterns, and careful handling of confidential work product. Add structured logging, tracing, transcript capture, metrics, tests, and debugging tools so agent behavior can be understood at both the engineering and product level. Partner with product, domain experts, backend, infrastructure, and security stakeholders to ensure end-to-end features are reliable across the browser, API layer, cloud services, and agent execution environment. Contribute to delivery discipline by writing clear technical notes, estimating work thoughtfully, supporting sprint planning, and continuously improving development practices. Desired Qualifications Bachelor's degree in Software Engineering, Engineering, or other relevant discipline with programming/technology experience, advanced degree desirable; 6+ years of professional software engineering experience, with strong hands-on ownership across frontend, backend, and production product systems; Strong TypeScript skills across the stack, including modern React development and Node.js/Express API development; Experience building component-driven React applications with complex state, multiple interconnected views, real-time updates, and user-facing workflows that require careful error handling; Experience building or consuming real-time interfaces using server-sent events, WebSockets, streaming APIs, or similar event-driven patterns; Experience building LLM-powered agentic systems that use tools, execute multi-turn workflows, manage state, and recover from errors; not just experience building static chatbots; Experience with LLM tool calling or function calling, including tool schema design, streaming tool input/output, multi-turn execution, and provider-specific implementation details; Strong prompt engineering ability for structured, multi-step workflows, including prompts that encode policies, methodology, roles, and tool usage expectations; Comfort working in Python for agent tools, data processing, automation, evaluation, and integration with analytical libraries; Good understanding of browser authentication flows, JWT lifecycle, token refresh, CORS, secure cookies, role-based access, and frontend/backend security boundaries; Familiarity with PostgreSQL and API-driven application design, including practical awareness of schema design, queries, migrations, and data access patterns; Experience with Docker or Linux-based execution environments and practical understanding of isolation, filesystem access, dependency management, and runtime troubleshooting; Strong product judgment, debugging instincts, documentation discipline, and ability to reason about AI behavior, software behavior, and user impact at the same time. Strongly Preferred Experience Experience designing custom agent frameworks, agent runtimes, orchestration loops, tool-extension systems, or evaluation harnesses rather than relying entirely on off-the-shelf frameworks. Experience with OpenAI, Anthropic, and other model provider APIs, including streaming, tool use, structured outputs, usage tracking, rate limits, and provider-specific failures. Experience with file-heavy web applications, including upload progress, large file handling, previewing, workspace navigation, generated-output review, and download flows. Experience rendering markdown, structured outputs, tool activity, logs, transcripts, plans, or other rich incremental content in React. Experience with sandboxed or ephemeral compute patterns, dynamically provisioned containers, secure credential injection, and session-scoped runtime lifecycles. Experience with Azure services such as Static Web Apps, Container Apps, Container Instances, Blob Storage, Azure Database for PostgreSQL, Application Insights, or related cloud services. Experience with Docker, GitHub Actions, CI/CD practices, structured logging, cloud observability, and collaboration in a distributed engineering environment. Experience with headless browser automation, document generation, data analysis, visualization, file conversion, R, LaTeX, or workflow automation tools. Experience working in consulting, professional services, legal, economic, healthcare, life sciences, energy, financial services, or other confidential/high-stakes environments. Familiarity with responsible AI practices, model evaluation, transcript review, quality controls, AI governance, and enterprise AI adoption.

Full Stack Engineer AviaryAI — Outbound AI voice agents for the financial services industry **Location:** Hybrid- NYC **(3+ days in office required)** **Type:** Full-time W-2 employee, subject to a 90-day introductory period\ \ Salary and equity commensurate with experience and performance --- ## About AviaryAI We build AI voice agents for banks, credit unions, and insurers. Our agents are live and handling real customer calls today. We’re backed by Y Combinator and growing. We started with voice. Our SMS and RCS agents began as clones of the voice product — and they’re growing fast. Messaging is becoming a major part of our platform, and it needs a dedicated owner --- ## The Role You’ll be a full stack engineer working across our platform — and you’ll head the engineering effort on our SMS and RCS expansion. This means: * Leading the engineering effort to evolve our SMS and RCS agents from voice-agent clones into a messaging-native product — rich cards, suggested replies, media, session handling * Writing the backend logic that manages conversation state and decision-making (Python) * Building internal dashboards and tools to configure and debug agents (TypeScript) * Contributing to our core frontend application as needed * Integrating with messaging providers and carrier infrastructure — delivery, 10DLC, opt-in/opt-out * Debugging real production issues when things break You’ll own the messaging vertical from prototype to high-volume production. This is not a ticket-driven role. You’ll have a lot of responsibility and a lot of autonomy. --- ## What We’re Looking For * 1–3 years full stack experience (new grads welcome) * Strong in Python * Comfortable in TypeScript / modern frontend frameworks * Experience building systems with real state or multi-step workflows * Comfortable integrating third-party APIs * Able to work without detailed specs Bonus if you’ve worked in: * Startups * Fintech / insurance * Messaging or telephony systems (Twilio, Telnyx, Bandwidth, SMS compliance) * LLM applications (prompting, agent frameworks, evals) --- ## What This Is Like You won’t just be building CRUD endpoints. You’ll be building systems that: * Decide what to say next in a live conversation — hours or days after the last message * Enforce business rules and compliance requirements (TCPA, carrier filtering, quiet hours) * Handle messy, real-world edge cases * Run thousands of concurrent conversations reliably Your code will power real conversations with real customers — and unlike voice, every word is in writing. Location: New York, NY, US Type: Full-time Salary: $100K - $130K Equity: 0.01% - 0.15% Experience: Any (new grads ok) Visa: US citizen/visa only Skills: Python, TypeScript
