You are an engineer who sees payment friction as a solvable logic puzzle and understands that HSA compliance is just as critical as UI responsiveness. Your days will focus on architecting resilient checkout flows in Next.js and Django that seamlessly bridge consumer ecommerce with complex financial regulations. We need someone who can debate TypeScript patterns in the morning and refine Python tax calculations by afternoon, ensuring every transaction clears without a hitch.

What they're looking for

  • 3 to 7 years of production experience building full stack applications with React, TypeScript, and Python.
  • Deep familiarity with payment gateways, tax-advantaged accounts (HSA/FSA), or regulated fintech environments.
  • Proven ability to design scalable backend services using Django alongside modern frontend frameworks like Next.js.
  • Strong sense of ownership over the entire development lifecycle from database schema to pixel-perfect interface.
