What you’ll be doing

• Lead end-to-end delivery of full stack solutions using Java Spring Boot, GraphQL/REST, and AWS-managed services, covering design through production support.
• Drive architecture and design reviews, including service boundaries, API contracts, data models, and integration patterns.
• Develop secure, high-quality, production-grade code and run thorough code reviews, setting and enforcing engineering standards.
• Build and maintain highly available, scalable services with operational excellence across reliability, performance, cost awareness, and maintainability.
• Implement and govern authentication and authorization using OIDC/OAuth2, including token validation and service-to-service security patterns.
• Establish observability practices with structured logging, metrics, and tracing, plus incident response readiness using runbooks.
• Evaluate vendor and internal options (fit, security posture, scalability, and operability) and guide adoption decisions.

What you bring

• 12+ years of applied full stack engineering experience delivering and operating production systems, including senior/lead capacity with technical leadership and design ownership.
• Expertise with Java Spring Boot: API development, dependency injection, validation, error handling, and performance tuning.
• GraphQL proficiency: schema design, resolvers, and federation/composition patterns (where applicable), plus query performance (N+1 mitigation, caching) and governance/versioning.
• REST proficiency: OpenAPI-style contract design, pagination/filtering, idempotency, backward compatibility, and consumer-driven API evolution.
• Hands-on OIDC/OAuth2 implementation, including JWT flows (access/refresh), scopes/claims, secure session patterns, and least-privilege access control.
• AWS (hands-on) experience designing, deploying, and operating cloud-native apps, with strong IAM understanding, networking basics, and operational tooling (logs/metrics/alarms).
• AWS Aurora PostgreSQL: advanced SQL, indexing, query optimization, migrations, and transactional design.
• AWS Neptune: Gremlin, graph modeling, query patterns, and performance considerations.
• AWS Kafka (MSK): topics/partitions, consumer groups, schema evolution, ordering and at-least-once semantics, idempotency, retries/DLQs, and monitoring.
• Strong Git practices and automated testing across unit, integration, contract, and end-to-end, with code quality gates and release confidence practices such as feature flags and progressive rollouts where applicable.
• Demonstrated proficiency using Claude Code and/or GitHub Copilot to accelerate development, debugging, refactoring, test generation, and documentation while ensuring correctness, security, and maintainability (including validating outputs, avoiding sensitive data leakage, and following team standards).
