• Design and execute test plans for RESTful APIs, Kafka message processors, and Redis-based job schedulers
• Build and maintain automated test suites (unit, integration, functional, end-to-end)
• Design and execute performance and load tests to validate system behavior under peak traffic, sustained load, and stress conditions
• Establish performance baselines, define SLAs (throughput, latency, error rates), and track regressions across releases
• Conduct soak tests to identify memory leaks, connection pool exhaustion, and resource degradation over time
• Validate Node.js library upgrades and dependency changes across the shared library ecosystem (lantern-utils, lantern-nest-utils, lantern-logger, lantern-requester, lantern-scheduler)
• Test containerized services in Docker and Kubernetes (EKS) environments
