Job responsibilities
Leads end-to-end delivery of full stack solutions using React Java Spring Boot GraphQL/REST and AWS-managed services from design through production support.
Drives architecture and design reviews defining service boundaries API contracts data models and integration patterns.
Develops secure high-quality production-grade code; conducts thorough code reviews; sets and enforces engineering standards.
Builds and maintains highly available and scalable services with strong operational excellence: reliability performance cost awareness and maintainability.
Implements and governs authentication/authorization using OIDC/OAuth2 token validation scopes/claims and service-to-service security patterns.
Establishes robust observability practices (structured logging metrics tracing) incident response readiness (runbooks).
Evaluates vendor and internal solutions (including architectural fit security posture scalability and operability) and guides adoption decisions.
Partners with Product and UX to deliver outcomes; translates requirements into technical plans and milestones; proactively manages trade-offs.
