> Staff Product Engineer leads technical direction for user-facing financial products, owning full-stack features from UI in React/TypeScript to APIs and backend services. Requires 8+ years experience, strong product instincts, architecture skills, and cross-functional leadership in San Francisco hybrid role.

## Job Description

## What You’ll Do
- Ship polished user experiences and own the APIs, data models, and backend services behind them. Care about the less visible details that matter, like page speed, API reliability, and responsiveness.
- Develop deep product expertise and use it to shape what we build. Partner closely with Product and Design to own roadmap decisions and influence product direction.
- Drive architecture decisions, write design docs, and lead technical reviews. Align stakeholders across Engineering and Data Science on priorities and tradeoffs.
- Define and implement observability across user interactions, Core Web Vitals, API performance, and perceived performance. Contribute to build systems, developer tooling, and deployment pipelines to improve how the team ships.
- Mentor engineers, improve team processes and code quality, and help foster a culture of craft, ownership, and high standards.

## What We’re Looking For
- 8+ years of experience building and shipping user-facing products as a full stack engineer, with a track record of owning large, ambiguous problem spaces and driving them from concept to production.
- Able to go deep across the stack to solve complex problems and unblock the team. You’ve built production-quality UIs in **React** and **TypeScript** and have experience designing APIs, working with data models, and debugging complex backend systems.
- You have strong product and user experience instincts and use them to influence what gets built, not just how it’s built. You consistently push for simple, high-quality user experiences.
- You think in systems and set technical direction that improves how the team builds. You are opinionated about how software should be built and establish abstractions, architecture, and patterns that make the broader product surface easier to develop and maintain.
- You lead through influence. You’ve driven cross-functional initiatives, aligned Engineering, Product, and Design around tradeoffs, and raised the bar for engineering quality through technical leadership, mentorship, and example.

**Bonus points**
- Experience in fintech, financial products, or embedded finance.
- Familiarity with **Python** or **Scala**.
