  • Ship event-driven features using Kafka/SQS with idempotent processing, retries, circuit breakers, and instant rollback capabilities (shadow/parallel modes).
  • Engineer for operations: Implement TDD, performance/load testing, OpenTelemetry traces/metrics/logs, meaningful SLOs, and production dashboards.
  • Work within a code repository with strict CI/CD pipelines, PR reviews, static analysis, and automated security scanning.

Technical Leadership & Strategy:

  • Architect platform-level services and improve systems for resilience, observability, and extensibility.
  • Make high-leverage engineering decisions that balance speed, quality, and maintainability.

Team Collaboration & Mentorship:

  • Partner with product, design, operations, and other engineering teams to build solutions that deliver business value and customer impact.
