Overview

Build backend systems at the intersection of banking infrastructure and developer-facing software. The engineering remit covers the core services behind payment processing, transaction logic and real-time ledgering. You will work within a small technical team and take ownership of systems where correctness and fault tolerance directly affect the movement of money.

Requirements

  • The work suits an engineer with strong backend judgment and an interest in distributed systems, financial infrastructure and clear API design.
  • No minimum number of years of experience is specified.

Responsibilities

  • Develop and maintain the banking platform's payment services and direct connections to the Federal Reserve and real-time networks.
  • Design APIs and data pipelines used by both internal teams and external developers.
  • Consider how transaction behavior, integration contracts and system safety fit together when making implementation decisions.
  • Improve resilience, scalability and visibility across a distributed architecture.
  • Lead changes that span platform capabilities, including authentication, authorization, event streams and change-data capture.
  • Evaluate the performance and failure behavior of code that operates close to payment flows, maintaining the engineering discipline required in a regulated environment.
  • Own production services with careful attention to correctness and reliability.

Conditions

  • This is a full-time position with a hybrid schedule in San Francisco, reporting directly to the chief executive.
