Role: SDET / Senior SDET — Backend & Scalable Automation
Team: Lenskart Platform Engineering
Experience: Substantial hands-on backend automation
Lenskart's warehouse management platform is a Kafka-driven ecosystem of roughly 40 microservices spanning procurement, receiving, the inventory ledger, picking, quality control, packing, manifesting, and dispatch. It's the system that decides how a pair of glasses moves from a vendor shipment to a customer's doorstep, across every geography Lenskart serves. It runs on async event chains, shared inventory ledgers, and dozens of services calling each other in real time — which makes testing it a genuinely different problem from testing a typical CRUD app.
· End-to-end automation across the fulfillment chain — picking → QC → packing → manifest → dispatch — spanning 30+ services, not a single app.
· Event-contract testing on Kafka — validating producer/consumer correctness across async hops (order hand-off, QC-pass events, manifest-close events, exception routing) where a broken contract fails silently until it doesn't.
· Data-consistency and reconciliation testing across the shared inventory ledger and the consolidated inventory layer — this is the class of bug that doesn't crash anything, it just quietly oversells stock across channels.
· Scaling the automation framework itself — distributed/parallelized test execution, containerized test runners, and CI/CD integration so suites stay fast as the service count keeps growing.
· API and contract testing across REST/Feign inter-service calls, plus failure-injection testing for the exception-management state machine (retries, dead-letter topics, escalation paths).
· Performance/load testing for peak-demand periods.
· Chaos testing for Blast radius.
· Partnering directly with engineering leads on quality gates and shift-left practices and sitting in architecture reviews for new services as a design-time voice, not a post-release gate.
· Mentoring — raising the automation bar across the SDET function, not just your own output.
· 2+ years in automation/SDET roles, with real depth in backend API automation (REST + message-driven systems), not primarily UI automation.
· Strong Java + a test framework (TestNG/JUnit, RestAssured or equivalent).
· Hands-on experience testing event-driven/Kafka-based architectures.
· Strong SQL and comfort reasoning about data consistency across distributed services.
· CI/CD experience (Jenkins/GitLab CI) and experience scaling test execution (parallelization, containerization).
· Solid grasp of microservices failure modes — idempotency, retries, eventual consistency, partial failure.
· Experience testing warehouse, OMS, or logistics/supply-chain platforms.
· Load-testing tools (JMeter/locust/gatiling/k6).
· Exposure to Elasticsearch, Redis, and observability tooling.
· Chaos-engineering or fault-injection experience.
A bug caught here isn't a UI glitch — it's a misship, a wrong invoice, or a SKU oversold across a live channel. Lenskart delivers across multiple geographies simultaneously, each with different tax regimes, couriers, and cutoff rules running through the same platform — building automation that holds up under that is a rare, senior-level problem, not a checkbox exercise.
