As a founding engineer, you'll touch the whole stack: front-end UIs, APIs, database schemas, system architecture, working in daily with our CTO to shape product and technical direction with the opportunity to grow into a leadership role as we scale. We're looking for someone who's shipped full-stack apps independently or on a team, is proficient in TypeScript, React, Node.js, and SQL, and thinks naturally in terms of API design and system architecture. You should be comfortable with Git, monorepos, and CI/CD (GitHub Actions). Bonus if you're familiar with T3 Stack, OpenTelemetry, and E2E testing.

We are in the process of raising our seed round and looking to hire within the next month. We are looking for someone remotely in the Bay Area, but are open to those who live outside of the region. We do not sponsor visas now or in the future. If you are interested, please reach out to View email address on click.appcast.io with your resume and linkedin profile.
