What You'll Do
* Ship software to prod on a daily basis with coding agents
* Influence UX through product engineering
* Collaborate with a high performing EPD team
Who You Are

* Operate with high agency: you identify what needs to be done and drive it forward without waiting to be told to
* Have found yourself wondering "why isn't this moving faster?" in previous roles — and then have done something about it
* 4+ years of demonstrable experience architecting and developing applications with Node
* Demonstrable experience writing type-safe code with TypeScript
* Strong ES6 Experience
* Experience using agents to ship to production
* Experience building applications with React and Node
* Experience with TypeORM is a plus
* Experience with TanStack Query is a plus
Stack
* Front-end: React + Redux Toolkit/React Query (Typescript)

Benefits
* Competitive pay and equity
* Unlimited PTO
