Observability and production excellence — expert: • Structured logging with correlation IDs; PII redaction discipline. • Metrics + SLO thinking: latency/error rate saturation signals; actionable alarms (not noise). • Tracing: Open Telemetry • Operability: runbooks, on-call readiness, meaningful postmortems with preventative actions. Testing and quality — expert: • Backend: JUnit5, Mockito, Spring test slices, Test containers; contract tests (Pact) preferred for service-to-service APIs. • Performance: basic load testing and interpreting results; capacity and tuning recommendations. • Security: SAST/dependency scans; remediates CVEs quickly and safely. Security (practical, senior-level) — non-negotiable: • AuthZ: RBAC/ABAC concepts; least privilege both in app and AWS IAM. • Secrets: no secrets in code/logs; uses managed secrets and rotation patterns. Additional Skills: • Full Stack Java Developer with Spring Batch, AWS(ECS, S3, Lambda), Infrastructure, Aurora Postgres DB, Kafka excellent communication. Note: • Contract position only, RTH not guaranteed at this time. Pay Range: $70/hr - $75/hr The specific compensation for this position will be determined by a number of factors, including the scope, complexity and location of the role as well as the cost of labor in the market; the skills, education, training, credentials and experience of the candidate; and other conditions of employment. Our full-time consultants have access to benefits including medical, dental, vision and 401K contributions as well as any other PTO, sick leave, and other benefits mandated by appliable state or localities where you reside or work.
