Sr. Full Stack Software Engineer/Architect

• 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 maintainshighly available and scalableservices 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.

• Minimum 8 years applied full stack engineering experience delivering and operating production systems; experience as a senior/lead capacity (technical leadership, design ownership).
• React expertise: modern React patterns, Type Script, state management, component design systems, performance optimization, and responsive UI development.
• Java Spring Boot expertise: building APIs, dependency injection, validation, error handling, and performance tuning.
• GraphQL proficiency: schema design, resolvers, federation/composition patterns (where applicable), query performance (N+1 mitigation, caching), and API governance/versioning strategy.
• REST proficiency:
  OpenAPI-style contract design, pagination/filtering, idempotency, backward compatibility, and consumer-driven API evolution.
• OIDC/OAuth2: hands-on implementation with JWTs, refresh/access token flows, scopes/claims, secure session patterns, and least-privilege access control.
• AWS experience (hands-on): designing, deploying, and operating cloud-native applications; strong understanding of IAM, networking basics, and operational tooling (logs/metrics/alarms).
• Data layer expertise: AWS Aurora PostgreSQL: advanced SQL, indexing, query optimization, migrations, and transactional design.
• AWS Neptune: gremlin, graph modeling, query patterns, and performance considerations for graph workloads.
• Event-driven systems: AWS Kafka (MSK): topics/partitions, consumer groups, schema evolution, ordering/at-least-once semantics, idempotency, retries/DLQs, and operational monitoring.
• CI/CD and quality:
  Strong Git practices, automated testing (unit/integration/contract/e2e), code quality gates, and release confidence practices (feature flags, progressive rollout where applicable).
• AI-assisted engineering (MUST):
  Demonstrated proficiency using Claude Codeand/orGitHub Copilotto accelerate development, debugging, refactoring, test generation, and documentation-while ensuring correctness, security, and maintainability (e.g., validating outputs, avoiding sensitive data leakage, and adhering to team standards).

• Infrastructure as Code (Terraform/Cloud Formation/CDK) and deployment automation patterns.
• Containerization and orchestration experience (Docker, ECS/EKS) depending on platform direction.
• Advanced security practices: threat modeling, OWASP Top 10 mitigation, secrets management, dependency hygiene.
• Experience defining platform standards: API governance, event contracts, service templates, and reliability SLOs/SLIs.
• Prior experience integrating with Oracle HCM.
