Requirements

  • Design and own distributed systems where correctness matters, with strong understanding of asynchronous processing and failure modes.
  • Have strong Go skills, or deep production experience in Java, Kotlin, Rust, or C# and be ready to ship Go within the first weeks.
  • Bring in-depth PostgreSQL experience, including schema design, query plans, locking, isolation levels, live-system migrations, and multi-tenant data.
  • Have end-to-end cloud ownership and working knowledge of AWS or GCP, including IAM, networking, managed databases, queues, and storage.
  • Be able to read and change Terraform and debug production using traces and logs.
  • Use coding agents such as Claude Code or Cursor every day, and be able to describe how you specify work and review agent output.
  • Have a track record of delivering large, technically difficult projects end to end and helping other engineers improve.
  • Typically have 8+ years building backend systems.
  • Write clearly and concisely in a remote company that makes decisions in documents and asynchronous threads.
  • Understand security fundamentals for sensitive data, including encryption in transit and at rest, key handling, personal-data minimization, and least-privilege access.

Responsibilities

  • Design and build core parts of the transaction platform.
  • Build for correctness under failure, with isolation and auditability for a regulated product.
  • Scale the platform as transaction volume and institutions per node grow while keeping latency predictable and the database healthy.
  • Write design documents and review other engineers’ designs and code.
  • Use AI agents and improve the specifications, context, and review practices that make agent-written code safe to ship.
  • Work with product, compliance, and customer-facing teams to turn regulatory and customer needs into software.
  • Own production delivery, including tracing, alerts, and incident follow-ups.
  • Mentor engineers and participate in an on-call rotation.
