Senior Software Engineer, Backend (Test Enablers)

Build and operate test-enablement platform capabilities that help engineers validate changes earlier and run safer, more reliable load and deterministic testing. You’ll help evolve Affirm’s testing strategy away from E2E-heavy validation toward scalable component, integration, contract, performance, and targeted E2E testing. Improve reliability, observability, and operational maturity with dashboards, SLOs, alerts, and runbooks, while partnering across teams to reduce false failures and accelerate validation loops.
