Keycard Labs

You'll build the **surfaces where agents and humans interact** with Keycard: console, CLI, and APIs. You'll shape how developers and agents **onboard, set policy, and investigate events**. This role sits on the primary customer-facing team, working across the full stack with React and Go.

You'll build and own the Keycard Agent SDK—libraries that bring trust and governance to **AI agents in production**. You'll build across Go, Python, TypeScript, and Rust, maintain compatibility with frameworks, and contribute to **open protocols like MCP and A2A**. Join a small team of repeat founders at a once-in-a-generation platform shift.

You'll build the core systems and infrastructure for Keycard, an identity and access control platform for the **agent-native era**. Your work will enable **secure and scalable agentic applications** at a company shaping the next generation of software infrastructure.

You'll design and build core identity, authentication, and authorization systems for Keycard's agent-native control plane. Your work will enable secure, multi-tenant agent operations at global scale with sub-10ms auth decisions. This is a chance to **define foundational technology** for the **agent-native era**.

You'll design and build operational data systems—pipelines, storage layers, and APIs—that power **near real-time enforcement** and **customer insights** for our identity platform. You'll balance streaming and batch paradigms to serve both transactional and analytical needs, working directly with founders and engineers. Join a small, distributed team building **agent-native infrastructure** from the ground up.
