Experience with CI/CD, infrastructure as code, and safe release practices (e.g. canary deployments, feature flags, automated rollback). Experience with observability tools (e.g. Datadog, Splunk, OpenTelemetry), service level objectives (SLOs), and building actionable alerts that detect issues before customers or partners do. Experience with event-driven architectures and messaging (e.g. Kafka or equivalent event streaming) and with SQL/NoSQL databases at scale (e.g. Aurora, DynamoDB). Understanding of security and privacy fundamentals for protecting sensitive customer and financial data (e.g. mTLS, PKI and certificate lifecycle management, JWT).
