PRIMARY ARCHITECTURE DOMAIN Vanilla JavaScript (ES6+) • Web Components (Custom Elements, Shadow DOM, HTML Templates) • MVVM Architecture • Pub-Sub Event Systems • Reactive UI State Management * NodeJS ROLE SUMMARY Seeking a focused and detail-oriented Software Engineer I to join our Core UI Platform team. In this role, you will move beyond standard monolithic frameworks to design, build, and maintain highly scalable, framework-agnostic No Code UI systems. You will leverage the native capabilities of modern browsers, specializing heavily in Vanilla JavaScript, W3C standard Web Components, and decoupling patterns such as Model-View-ViewModel (MVVM) and Publish-Subscribe (Pub-Sub). As an SE I, you will work within an agile squad dedicated to delivering modular, ultra-high-performance UI elements that form the foundational micro-frontends of our enterprise cloud applications. This position is ideal for an engineer who wants to master browser internals, write memory-efficient code, and build foundational architectural systems rather than just consuming third-party UI frameworks. KEY RESPONSIBILITIES 1. Component Engineering & Modular UI Development Design, implement, and maintain reusable, performant, and framework-agnostic UI components using modern native Web Component standards (Custom Elements v1, Shadow DOM v1, and HTML Templates). Ensure components adhere strictly to accessibility standards (WCAG 2.1 AA, ARIA roles) and semantic HTML practices. Optimize component performance, minimizing layout thrashing, excessive repaints, and memory leaks caused by improper lifecycle management or dangling DOM references. 2. Architecture & State Management Implementation Implement structured client-side architectures based on the Model-View-ViewModel (MVVM) pattern, facilitating clean data binding and strict separation of UI layout from business logic. Utilize Publish-Subscribe (Pub-Sub) patterns, custom event brokers, and message buses to drive decoupled, asynchronous, inter-component communication across disparate micro-frontends. Maintain localized component states and bind them reliably to global application states using asynchronous JavaScript workflows (Promises, Async/Await, Observables). 3. Testing, Documentation & Technical Quality Write robust unit and integration tests for custom components and modules using modern assertion libraries (e.g., Web Component Tester, Jest, Mocha, or Playwright). Document technical designs, architectural decisions, and component APIs using comprehensive JSdoc annotations and Storybook catalogs. Participate proactively in peer code reviews, adhering to organizational guidelines for code cleanliness, functional design patterns, and cross-browser interoperability. TECHNICAL COMPETENCIES & MATRIX Below is the expected competency landscape for an engineer joining at the SE I level: Domain Expected Capabilities (SE I Level) Key Technologies / Concepts Core JavaScript Profound understanding of prototypes, closures, event loops, scopes, execution contexts, hoisting, and deep vs. shallow cloning. Fluent in ES6+ syntax. ES2022+ Async/Await Closures Event Loop Web Components: Ability to author components from scratch. Proficient with Shadow DOM boundaries (open vs. closed), slot composition, and lifecycle callbacks. Custom Elements v1 Shadow DOM HTML Templates LitElement / Lit Design Patterns: Clear separation of concerns using MVVM. Experience building functional 1-way or 2-way data bindings and implementing custom decoupled Pub-Sub message buses. MVVM Pub-Sub Pattern Observer Pattern Data Binding DOM & Events Handling DOM events safely using capture/bubble phases, event delegation, custom event dispatching, and memory cleanup. Event Delegation CustomEvents Pointer Events REQUIREMENTS & QUALIFICATIONS Minimum Qualifications Experience: 1+ years of professional front-end engineering experience writing production-grade enterprise client-side web applications. Core Expertise: Strong proficiency in vanilla JavaScript (ES6+), semantic CSS3/HTML5, and modern browser APIs. Component Standards: Hands-on experience developing native Web Components or working extensively with lightweight component base-classes like Lit, Stencil, or vanilla APIs. Architectural Concepts: Practical familiarity with the Pub-Sub pattern, decoupling UI state, and handling complex asynchronous event propagation across separate modules. Preferred Qualifications Experience working within monorepos or enterprise-scale Micro-Frontend systems. Familiarity with Custom Element structural optimizations, such as declarative shadow DOM and CSS Understanding of bundle optimization, tree-shaking, and asset delivery pipelines using modern tools such as Vite, Webpack, or Rollup. Strong grasp of cross-browser performance profiling, memory leak investigation via browser DevTools, and performance budgeting.

We’re in an unbelievably exciting area of tech and are fundamentally reshaping the data storage industry. Here, you lead with…

At Replicant, we believe AI should work for people, starting with customer service. That's why we built a platform that helps contact centers resolve more requests, proactively identify issues, and improve agent performance with AI-powered conversation intelligence and AI agents that act like your best reps. Our AI agents handle millions of calls every month for Fortune 500 companies and high-growth innovators. From processing payments to booking appointments and authenticating users, they help customers get what they need instantly, 24/7. Meanwhile, our real-time conversation insights help contact center leaders coach better and improve every interaction. We are leading the shift from legacy systems to AI-first service, powered by large language models (LLMs) and designed for enterprise scale, security, and empathy. If you're excited by the potential of LLMs, voice AI, and building category-defining technology with a kind, ambitious team, you'll love it here. Our customers don't buy software. They buy a working AI agent that answers their calls, resolves their customers' problems, and holds up in production. As a Senior Software Engineer, Agents on our Delivery team, you make that happen for specific customers: you sit with them to understand their workflows, design and write the agent's instructions and conversation behavior, build the integrations the agent calls as tools, and own the agent end to end from blank prompt to production. This is a customer-embedded engineering role, equal parts trusted advisor, integration builder, and prompt engineer, and you are measured on customer outcomes, not features shipped. It's also one of the most in-demand emerging skill sets in the market, and you'll build it on real production traffic, not demos, with real autonomy on a team small enough that your work is visible to customers and leadership alike. What You'll Do Own AI agents for your assigned customers across the full lifecycle: discovery, design, build, evaluation, launch, and live operation. Sit with customers, map their workflows, and translate ambiguous business goals into a concrete agent scope: what the agent handles, what it escalates, and what success looks like. Uncover the customer's real business rules, including the unwritten ones, and pin them down so the agent enforces that business logic strictly. Design and write the agent's prompts, instructions, and conversation flows, and iterate against evals, real transcripts, and your own product taste for what a good conversation sounds like. Wire the agent into customer systems (CRMs, ticketing, internal services): call their APIs as tools, shape inputs and outputs so tool calls are reliable, and handle auth, errors, and edge cases. You won't build the customer's APIs, but you will tell them what the agent needs from an API, then test and validate what they deliver. Build test sets from real cases covering not just the happy path but unhappy paths, edge cases, and hallucination risks; measure agent quality and harden agents for production: guardrails, failure modes, latency, and cost. Monitor live conversations and tool-call health, debug from logs and transcripts, and ship fixes under pressure. Feed recurring patterns and missing capabilities back to Product so each agent makes the next one faster to build. What You'll Bring Customer-facing strength. You can sit across from a customer, converse credibly, and earn trust quickly, including with skeptical stakeholders. You decompose ambiguous, sometimes politically loaded business problems into a concrete plan, communicate clearly with both technical and non-technical audiences, and push back when a request is feasible but wrong. Integration fluency. You understand and can shape integration patterns: how to connect an agent to a customer's APIs, endpoints, and protocols, design clean tool schemas, and handle auth, errors, and edge cases so tool calls are reliable. You validate bespoke, sometimes under-documented customer APIs before an agent depends on them, and you're comfortable with external and third-party systems beyond the customer's own stack. Prompt and instruction craft. You can shape LLM behaviour through structure, instructions, and examples, you write instructions that are unambiguous and easy to follow, and you know why a prompt fails. You work eval-first, and you bring product taste: a feel for what a good conversation sounds like, not just what passes the tests. Nice to have: general-purpose coding experience (TypeScript, Python, SQL); prior forward-deployed, solutions engineering, or customer-embedded work; conversational AI, voice, or contact center domain experience; experience with LLM evaluation tooling and observability. A computer science degree or a software engineering title is not required. If your background is systems administration, integration engineering, technical support, or anywhere else you learned how systems talk to each other by taking them apart, we want to hear from you.

It is critical that everyone who joins the team feels excited and moved by these values as every new team member makes an impact on our culture. Blade Runners: We take ownership and pride to influence the outcomes of our goals. We are successful, and like a Blade Runner, use the tools at our disposal to reach our objectives. We value open and honest communication and proactively seek feedback along the way. We are a company driven to grow and achieve both individually and as a team. Bread Makers: We are humble and strive toward an egalitarian culture. No task is too big or too small. We work together to achieve our goals and develop our company mission. We believe that the whole is greater than the sum of its parts in everything that we do. Självdistans (Self-Distance): Självdistans is Swedish for self-distance. It's the ability to critically reflect on oneself and one's relations from an external perspective. With this in mind, we act with objectivity and always remember that we are not our work. There's no perfect science to growing a team or business, but we trust everyone at Replicant to point out our blind spots and humbly admit their own. Replicant is proud to be an equal opportunity employer. We are committed to fostering an inclusive, diverse and equitable workplace that is built on trust, support and respect.
