Senior Fullstack Engineer
Circleback, San Francisco
The role
This is a senior individual contributor role for someone who can take a genuinely ambiguous problem, figure out what the team should build, and carry it through to production. You’ll work across the product and stack, make technical decisions that shape how we build beyond a single feature, and help raise the bar for the rest of the engineering team. We’re looking for someone who can see how the pieces fit together, make good calls without a lot of structure, and still stay close to the code.
What you will do
- You’ll build across the product: web with React, Next.js, Prisma, and SWR; desktop with Electron and Swift; and mobile with React Native.
- Take on ambiguous problems, figure out the right approach, and ship them across the full stack.
- Set technical direction, not just execute it.
- Work on AI-powered workflows, search, transcription, automations, and performance.
- Raise the engineering bar through code review, mentorship, and shared tooling.
