Software Engineer - AI Tooling (Remote - Worldwide)

Work is asynchronous across a globally distributed team. A fast-growing developer platform company offering a full backend stack built on PostgreSQL, including database, authentication, storage, serverless functions, realtime and vector search. You will join the AI tooling team, which builds the agent-facing layer of the product: an MCP server, agent skills, internal agents and an in-dashboard assistant. The team works eval-first, so every tool is expected to prove with measurements that it improves agent outcomes.

What you'll do

• Build and maintain the existing AI tooling, including the MCP server, agent skills, agents and the dashboard assistant.
• Prototype tools for new product surfaces and new AI techniques, evaluate them honestly, and help decide which ones go to production.
• Create and improve evals, instrumentation and feedback loops, comparing tool-enabled performance against a no-tool baseline and helping set quality gates that block regressions.
• Design how documentation and product knowledge are exposed to agents, and measure how well that works.
• Centralise shared AI logic and create templates and docs so other teams can contribute safely.
• Partner with infrastructure, docs, CLI, frontend and SDK teams to deliver one consistent developer experience.

What you need

• 5+ years of professional software engineering experience.
• Strong TypeScript and solid knowledge of the JavaScript ecosystem, including npm, ES modules, bundlers and compatibility.
• Hands-on familiarity with current AI tools and agent patterns, with the judgement to separate durable approaches from hype.
• Experience building developer tools, product interfaces or platform primitives used by other engineers.
• Experience designing or using evaluation frameworks for AI quality, reliability and task success, including baselines, variance and cost.
• Working knowledge of PostgreSQL and relational database practice.
• Clear written communication and comfort working asynchronously across time zones.
