  • Write clean, testable code and create unit, integration, regression, and performance tests.
  • Participate in architecture discussions, code reviews, estimation, sprint ceremonies, deployments, and operational support.
  • Apply engineering standards for security, reliability, scalability, performance, observability, and maintainability.
  • Collaborate with architects, product owners, analysts, QA engineers, and other domain squads to manage dependencies and integrations.
  • Communicate technical risks, blockers, assumptions, and delivery progress.
  • Contribute reusable prompts, workflows, patterns, and practices that support a repeatable Claude Code and Claude Cowork-enabled software development lifecycle.
  • Take end-to-end ownership of software artifacts from analysis and design through deployment and support.
