Senior SDET – (India)

Job Overview
We are looking for a Senior SDET to test the resilience and correctness of distributed backend systems supporting a high-stakes account provisioning and onboarding workflow. This role is focused on the execution of pre-approved, benign tracer/replay scenarios against staging endpoints, analysis of request/response behaviour, and documentation of observable account/CID lifecycle and downstream state behaviour.<span data-ccp-props="{"134233117":false,"134233118":false,"335551550":6,"335551620":6,"335559738":240,"335559739":240}">
The ideal candidate has strong distributed-systems and API-testing experience and maintains disciplined technical evidence capture and traceability.<span data-ccp-props="{"134233117":false,"134233118":false,"335551550":6,"335551620":6,"335559738":240,"335559739":240}">
