About the Role

Founding Product Engineer

Join as the third engineer building the financial account for groups. You will own features end-to-end, from crafting intuitive UIs in React to architecting backend services in Go. This is a high-impact role at an early-stage startup where your work directly enables co-ownership of money for thousands of users.

Location: San Francisco, USA

Why this role is remarkable:

  • Join an elite three-person engineering team led by a YC alum and former Block/Cash App leaders who have previously scaled payment products to 50k+ users.
  • Shape the foundational codebase and product direction of a company with $4.5M in funding and a waitlist of thousands eager for better shared banking.
  • Tackle complex consumer UX challenges in fintech, creating sophisticated role-based permissions and spending controls that feel effortless for everyday users.

What you will do:

  • Design, build, and ship high-quality consumer features using a modern stack of TypeScript, React, Go, and PostgreSQL.
  • Collaborate directly with the founder and engineering lead to scope product requirements and architect resilient financial infrastructure on AWS.
  • Leverage emerging AI tools to accelerate development speed while maintaining the high bar for detail required in a trusted payment application.

The ideal candidate:

  • Significant professional experience with React and TypeScript, demonstrating a strong product sense and obsession with high-quality consumer UX details.
  • Proven track record of shipping meaningful products from scratch, ideally as an early or founding engineer at a fast-growing startup.
  • Technical flexibility to work across the stack, with a willingness to master Go and manage infrastructure using Terraform and Docker.
