Requirements
- 5+ years building customer-facing products, including features you took from concept to GA and owned afterward.
- Comfortable owning work on both sides of the stack: React and TypeScript on the frontend, and Python API/service on the backend.
- Ability to independently own meaningful frontend and backend work.
- Strong product sense: translate ambiguous needs into clear requirements, make sound scope calls, and provide critical feedback on designs.
- Startup-style range: experience owning work at both ends of the stack and moving it forward with limited direction.
- Comfortable working with real production data, including understanding data models and investigating production issues.
- Fluent with AI development tools and data-driven decision making.
Responsibilities
- Build customer-facing features end to end, from UI and interaction design through the supporting APIs, services, and data.
- Own and evolve our API/service layer and data models with the same depth as the frontend.
- Take features from early prototype to a polished, reliable GA experience, then keep iterating on them.
- Partner with product and design in shaping what gets built and why, turning ambiguous customer needs into clear scope.
- Ship behind feature flags, instrument what you build, and run experiments with a stated hypothesis so you know whether it worked.
- Hold the quality bar on public surfaces: performance, accessibility, and the data accuracy customers rely on to make financial decisions.
- Use AI tooling heavily to prototype, build, and review faster.
