About the Role

A well-funded, early-stage fintech startup is looking for a Founding Product Engineer to join a small, senior team building a new kind of collaborative financial product. You'll have broad ownership across the stack, working directly with the founding team to ship high-quality, polished features for a consumer-facing application with a 40,000+ person waitlist.

What You'll Do

Design, develop, and deliver features, fixes, and improvements across the core product, marketing site, and internal tools.

Work closely with the founder, lead engineer, and designer to architect and implement solutions that delight users.

Build and wire up APIs across a full stack of React, TypeScript, Go, and PostgreSQL.

Leverage AI tools to accelerate development and contribute to a culture of high-quality engineering.

Help scale the product to meet rapidly growing consumer demand.

Required

Strong proficiency in TypeScript (React) on the front end and comfort with Go on the back end.

Prior experience shipping and maintaining features for B2C / consumer-facing products.

Solid experience with PostgreSQL and Redis.

Familiarity with AWS, Terraform, and Docker for infrastructure and deployment.

Experience building and integrating REST or GraphQL APIs.

Comfortable working in a fast-paced, early-stage startup environment with broad ownership.

Nice to Have

Experience using AI coding assistants and prototyping tools to accelerate development.

Background in fintech, payments, or financial services.

Familiarity with tools like Slack, Linear, GitHub, and Figma.
