SDET-QA

Bangalore Full-Time Senior

About this role

About the team

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.

What you'll own

• 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.

Job

Must-have

• 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.

Nice-to-have

• 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.

Why this role matters

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.
