Senior Product Engineer

Parafin•San Francisco, CA

About The Position

We're looking for a full stack engineer to join our Product Engineering team in San Francisco. Our team owns the end-to-end experience across Parafin's financial products, from the UI layer down to the APIs and services that power it. You'll work across Design, Product, and Engineering to build high-quality user-facing products. As a Senior Product Engineer, you'll own large product areas end-to-end, from scoping projects to making technical decisions and driving outcomes. You'll have a direct hand in shaping what we build and how it’s built.

Requirements

5+ years of experience building and shipping user-facing products, with experience owning projects end-to-end and driving them from scoping through execution.
Comfortable working across the stack and going deep where needed. You’ve built production-quality UIs in React and have experience building APIs, working with databases, and debugging backend systems.
You care deeply about user experience and can reason about what makes one UX better than another. You think through edge cases when data is missing or when users do something unexpected.
You are opinionated about how software should be built and contribute to abstractions, architecture, and patterns that make the product easier to develop and maintain.
You’re a strong cross-functional collaborator who works effectively with Engineering, Product, and Design to drive projects forward, align on tradeoffs, and deliver high-quality outcomes.

Responsibilities

Ship polished user experiences and own the APIs, data models, and backend services behind them. Care about the details that matter, like performance, reliability, and responsiveness.
Develop strong product context and use it to shape what we build. Partner with Product and Design to inform roadmap decisions and improve the user experience, not just execute on specs.
Make sound technical decisions and contribute to architecture and design. Participate in design reviews and collaborate with Engineering to align on tradeoffs.
Improve code quality, systems, and team processes. Mentor other engineers and help foster a culture of craft and ownership.
