Translate architectural direction into executable sprints, technical designs, and working software

Write production code—expect to spend 40-60% of your time hands-on in the codebase

Drive engineering quality: code reviews, testing strategy, incident response, and on-call practices

Manage team health: hiring, career development, 1:1s, performance management

Partner with the processor's technical team on API contracts, certification, and production readiness

Ensure the team meets the latency, reliability, and compliance requirements inherent to payment authorization
