Senior Fullstack Engineer

We’re building an AI-first delivery system where agents ship product features end-to-end, and engineers build the platform (the harness) that makes it safe, reliable, and scalable. This is a hands-on delivery role with a focus on shipping product features.

Your day to day:

• Design and build robust, scalable solutions for complex problems, balancing performance, maintainability, and delivery speed
• Design and implement agentic workflows that take a requirement from spec → code → review → deploy
• Produce clean, well-tested, maintainable code across our TypeScript/React/Node stack
• Use AI coding agent tooling as part of your day-to-day workflow
• Suggest and implement process or technical improvements that make the team more effectiv

What We're Looking For

• Strong fullstack engineering ability. You can design and ship robust, scalable systems, not just features to a spec. You think about maintainability and trade-offs as you go.
• Genuine delivery orientation. You want to be shipping product, working closely with a small team, and taking ownership of outcomes rather than just tickets.

What we need from you

• Must have advanced knowledge of TypeScript, JavaScript, React, SQL, and Node.js
• Experience building large-scale software applications in production
• You can read a codebase and quickly identify its patterns, conventions, and architecture
• You are comfortable working in ambiguity and turning fuzzy intent into clear acceptance criteria + evals
• Experience with unit/integration testing
• Experience with AWS services or similar cloud infrastructure
• Familiarity with agent tooling concepts: tool calling, MCP/tool integration, guardrails, evals, tracing/observability, and permissioning
