Full Stack Founding Engineer in Hedge Fund Analytics Startup
About the role
We are looking for a strong founding engineer to join Bayesline as an early, high-leverage member of the team.
This is a generalist role for someone who is strongest in building product and systems end-to-end, and who is comfortable moving across a Python-first, API-driven analytics platform. A meaningful part of the role will involve shaping a sophisticated user-facing product, so strong product and UI judgment matters, but this is not a front-end-only role.
This is not a greenfield build. You will be joining an existing codebase with substantial functionality and real product complexity already in place. The opportunity is to improve, extend, and unify a fast-moving platform used for portfolio risk, performance attribution, scenario analysis, custom factors, dashboards, and chart-driven workflows.
You will work directly with the founders and alongside our founding engineer on a small, high-agency team. This role is best suited to someone who is comfortable working independently, making sound technical and product decisions, and taking broad ownership without relying on a large, specialized organization around them.
What We’re Looking For
• Strong software engineering fundamentals and experience building real products end-to-end, including front-end
• Comfort operating as a generalist across product, backend, APIs, and user-facing systems
• Experience shipping complex, data-heavy applications rather than simple CRUD apps
• Strong product instincts and sound judgment around front-end architecture
• Comfort working in a Python-first, API-driven environment with React and Typescript front-end and actively building across both the back and front-end as part of the role
• Comfort using AI in day-to-day development, with the judgment to evaluate and improve AI-generated code and ideas
