What You'll Do
- Work with founders, product, AI, operations and domain experts as you fully own substantial product and platform work from problem definition through production rollout.
- Build backend systems that can handle real production complexity: clear APIs, well-modeled data, reliable execution, useful observability, and maintainable code.
- Turn messy operational workflows into clean software abstractions, internal tools, automations, and customer-facing features.
- Continuously help the team discover where AI meaningfully improves software quality and velocity, and where it doesn't.
- Improve the engineering system itself: better tools, better patterns, better deployment practices, better observability, fewer repeated mistakes, less accumulated technical debt.
- Mentor other engineers by raising the quality of design discussions, implementation choices, reviews, and production ownership.
Who We're Looking For
- 10+ years of professional software engineering experience with deep backend expertise.
- Your default process integrates AI tools into your daily engineering workflows to continuously improve velocity and quality.
- A track record of building and operating real production systems.
- Excellent instincts around APIs, data modeling, databases, queues, reliability, performance, and operational simplicity.
- Frontend ability to build and polish product experiences when needed.
- Experience working in an early-stage environment where requirements are incomplete, priorities shift, and ownership is broad.
- Strong product judgment: shipping code solving the problem.
- A pragmatic approach to architecture: you know when to design carefully, when to ship the simple version, and when to delete complexity.
- You can lead projects, take feedback, engage in thoughtful discussion, and get the work done.
- Experience building AI-enabled products, internal platforms, workflow systems, or developer tools.
- Experience with TypeScript, React, Python, Julia, Java, Go, or similar technologies.
- Experience with Postgres, AWS, data pipelines, document processing, integrations, or compliance-sensitive systems.
