Staff Backend Software Engineer

The role

You will design and build core parts of a transaction platform written in Go. You will scale the platform, write design docs, mentor engineers, and work with product and compliance teams.

What you will do

• Design and build core parts of our transaction platform.
• Build for correctness under failure, with the isolation and auditability a regulated product needs.
• Scale the platform as transaction volume and the number of institutions per node grow.
• Write design docs for what you build.
• Give sharp, useful reviews on other people's designs and code.
• Build with AI agents every day.
• Work with product, compliance and customer-facing teams.
• Own what you ship in production, from tracing and alerts to incident follow-ups.
• Mentor engineers on the team.
• Work on an on call rotation

• AI-native engineering. Use coding agents such as Claude Code or Cursor every day.
• Staff-level experience. Typically 8+ years building backend systems.
