Requirements

Experience (1) using Kubernetes/Helm, IBM Bluemix (IBM Cloud), and PCF with GitOps CI/CD and blue-green/canary strategies to deploy and operate microservices with zero-downtime rollouts and make clear trade-offs (latency, throughput, cost, RPO/RTO).
Experience (2) using Kafka (with Connect) and RabbitMQ alongside Hadoop/Spark—plus schema governance and CDC - to build and run SLO-driven streaming/data pipelines (reliability/latency/throughput), including partitioning/windowing, exactly-/at-least-once semantics, backfills, and cost-aware scaling.
Experience (3) using Java/Spring Boot and Node.js with Redis, MySQL, and Cassandra to implement a polyglot data layer (Redis for caching/rate-limits and counters; MySQL for transactional/admin workflows; Cassandra for high-volume telemetry/time-series), expose REST/gRPC APIs, and automate build/test/deploy via CI/CD and shell scripting.
Experience (4) using requirements engineering practices (SRS, user stories, acceptance criteria) with system-engineering collaboration to define implementable system/automation requirements, map non-functionals (security, reliability, latency), and maintain traceability to implementation and tests.
Experience (5) using security and observability stacks OAuth2/OIDC, mTLS, secrets management, RBAC/ABAC, secure-SDLC, and logs/metrics/traces with OpenTelemetry, Prometheus/Grafana or ELK to harden services and data tiers and operate to actionable SLOs/error budgets.
Experience (6) using lightweight PoCs, technical evaluations, and thorough documentation (how-it-works guides, system/design diagrams, presentations, manager-ready write-ups) to validate new frameworks in the stack (Kafka/RabbitMQ, Spark, Spring Boot/Node.js) and drive measurable system/process improvements.
Master’s degree in Computer Science, Engineering, or related, and 3 years of relevant work experience.
Bachelor’s degree in Computer Science, Engineering, or related, and 5 years of relevant work experience.
