  • Identify recurring integration patterns and common failure modes
  • Maintain and improve internal tooling, runbooks, and documentation

  • Webhook debugging: delivery and retries, signature verification, and diagnosing missed, late or duplicate events
  • Working knowledge of API authentication, including API keys and HMAC request signing, and of idempotency keys and retry behavior
  • SQL: write your own queries (joins, filters, aggregates) against PostgreSQL to trace records
  • Scripting in Python (or similar) to reproduce issues, automate checks and build internal tools
  • Log and trace search in Datadog (or Splunk or similar)
