Senior Full-Stack Engineer

Ship the product that moves real money across borders.

We're building regulated financial infrastructure on top of compliant banking rails. You'll join a tight engineering team, own full features end-to-end, and ship fast without cutting corners on correctness. Architecture decisions are made as a team — everyone's opinion matters here.

  • Work closely with the engineering team on payment rails, webhook reliability, and settlement logic
  • Build and maintain compliance infrastructure: audit logs, monitoring pipelines, and data integrity systems
  • Ship customer-facing product: onboarding, transaction history, and account management
  • Improve reliability through idempotency, error handling, observability, and alerting
  • Contribute to architecture decisions alongside the engineering team

Requirements

  • 6+ years full-stack engineering — fintech, payments, or regulated infrastructure strongly preferred
  • Strong in TypeScript / Node.js on the backend; React on the frontend
  • Solid understanding of payment systems: ACH, SEPA, WIRE, webhooks, and settlement flows
  • Experience with compliance-adjacent engineering: event logging, audit trails, and data integrity
  • Postgres, Redis, and event-driven architecture at production scale
  • High standards for code quality, testing, and operational reliability

Nice to have

  • +Experience with BaaS providers and regulated payment infrastructure
  • +On-chain experience: USDC, stablecoin infrastructure, or L2 networks
  • +Prior experience at an early-stage fintech or payments company

What we offer

  • Competitive senior salary + significant founding equity
  • Work with a high-trust engineering team that moves fast and owns its work
  • Remote-first, async culture
  • Real influence over architecture and product direction
