Senior Software Engineer, AI-Driven Systems

Thimble is investing in the next generation of its platform, and this engineer helps lead that work. Our backend is built on Node.js microservices and event-driven architecture on AWS, and we are evolving it toward durable, explicitly orchestrated workflows, with AI-native tooling at the center of how we build.

This is a hands-on role: you’ll write, review, and ship production code every day, with AI agents as your primary build partner. You’ll also shape technical strategy and set the patterns the rest of the team builds on.

You’ll work in Node.js and TypeScript every day, so you need to be productive in them from the start.
