- Help improve cross-stack developer experience (shared contracts typing integration patterns tooling)
- Occasionally contribute to frontend-adjacent work to unblock teams or improve end-to-end reliability while remaining primarily backend-focused
- Drive pragmatic decision-making: refactor vs. rebuild prioritization sequencing of change
- Mentor senior engineers and raise the bar through reviews coaching shared patterns and architectural guidance
Requirements
- 8 years of engineering experience (or equivalent impact)
- Strong hands-on backend experience in AWS including Lambda IAM API Gateway and event-driven services
- Strong TypeScript expertise in backend/service contexts
- Proven ability to lead system-level transformations in production environments (not just greenfield)
- Strong understanding of distributed systems failure modes and operational trade-offs
- Ability to think in terms of platform leverage: shared primitives safer defaults automation and developer experience
- Experience decomposing monoliths or untangling tightly coupled services
- Experience working with data stores (SQL and/or NoSQL) in distributed systems
- Practical knowledge of Infrastructure-as-Code (CDK and/or Terraform) CI/CD and modern cloud tooling
- Solid security mindset: IAM design least privilege secure service patterns and a healthy respect for compliance requirements
