Founding Engineer

About the role

We're looking for a Founding Engineer to help build core product and infrastructure from the ground up. You'll partner directly with the CEO and CTO, ship quickly, iterate constantly, and make smart technical tradeoffs. You'll be responsible for owning major parts of the stack from design to execution.

What You’ll Do

• Partner directly with the CEO and CTO on building core product and infrastructure from the ground up
• Own major parts of the stack end to end from design to execution
• Ship quickly, iterate constantly, and make smart technical tradeoffs
• Savvy with agentic coding and product development tools — you can use as many tokens as you need
• Be a foundational cultural anchor for the company by shaping what we do, how we work, and what values we hold close

What We’re Looking For

• Strong technical skills
• Frontend: React/NextJS/TypeScript; component-driven development, performance profiling, accessibility, data fetching/state, etc.
• Backend: Python FastAPI, background workers/queues, Postgres, object storage, etc.
• Experience with testing and observability (unit/integration tests, metrics, traces, structured logs)
• Experience building and shipping real products in fast-moving environments
• LLM/agent experience — you must have created your own agents before
• Great product instincts and genuine care for design, UX, and human-centered product development
• Comfortable with ambiguity, ownership, and figuring things out without waiting for perfect specs
• Clear communicator with high standards, low ego, and strong opinions held loosely
• Curious, growth-oriented, and a tinkerer at heart
• If you want to be early, close to the work, and hands-on in building something people truly love, we'd love to talk.
