Financial tools for the 130 million Americans living paycheck to paycheck, starting with instant cash advances.

Senior Backend Engineer

SeattleOn-site$120K - $200K2 - 5 years
We’re building a financial safety net for people traditional banks have left behind — products that deliver real cash in minutes, not days, and a path toward genuine credit health. As a Senior Backend Engineer, you’ll shape the systems that move money reliably, underwrite risk in real time, and scale to millions of users who depend on us when they have nowhere else to turn. You’ll own services end-to-end, from designing data models and APIs to deploying on Kubernetes and observing behavior in production. This is backend work with tangible stakes: every latency spike or reconciliation error has a human cost, and every architectural decision compounds across a lean, high-trust engineering team.

What they're looking for

  • 2–5 years building and operating backend services, ideally in Go
  • Deep comfort with MySQL or similar relational databases at scale
  • Experience deploying and debugging workloads on Kubernetes in GCP (or equivalent cloud)
  • A demonstrated instinct for data integrity — you've worked on systems where correctness is non-negotiable
  • Clear communication and a preference for solving problems collaboratively in an on-site, Seattle- or San Francisco-based team
