· Build and maintain highly available, scalable services with a focus on reliability, performance, cost awareness, and maintainability.
· Implement authentication and authorization using OIDC, OAuth 2.0, JWTs, scopes, claims, and secure service-to-service patterns.
· Establish observability practices across structured logging, metrics, tracing, alerts, incident readiness, and runbooks.
· Evaluate internal and vendor solutions for architectural fit, security, scalability, and operability, and guide adoption decisions.
What You Need to Be Considered
· Advanced hands-on expertise in Java and Spring Boot, including API development, dependency injection, validation, error handling, and performance tuning.
· Strong GraphQL experience with schema design, resolvers, federation or composition patterns, query optimization, caching, and API governance.
· Strong REST API experience, including contract design, pagination, filtering, idempotency, backward compatibility, and consumer-driven evolution.
· Hands-on implementation of OIDC and OAuth 2.0 using JWTs, token flows, scopes, claims, secure session patterns, and least-privilege access controls.
· Strong AWS experience designing, deploying, and operating cloud-native applications, including IAM, networking fundamentals, logs, metrics, and alarms.
· Advanced experience with Aurora PostgreSQL, including SQL, indexing, query optimization, migrations, and transactional design.
· Experience with AWS Neptune, graph modeling, Gremlin queries, and performance considerations for graph workloads.
· Experience with Amazon MSK or Kafka, including topics, partitions, consumer groups, schema evolution, delivery semantics, idempotency, retries, dead-letter queues, and monitoring.
· Strong Git, CI/CD, and automated testing practices across unit, integration, contract, and end-to-end testing.
· Demonstrated proficiency using Claude Code and/or GitHub Copilot responsibly for development, debugging, refactoring, test generation, and documentation.
