Senior SDET – India

• Analyze distributed system APIs to validate correctness, consistency, and failure handling across services involved in account creation, data persistence, and related record-linking
• Execute pre-approved request variations and boundary-validation scenarios using sanitized tracer payloads against designated staging endpoints
• Investigate system behavior under malformed, malicious, or unexpected inputs and document findings clearly
• Capture complete request/response evidence, including HTTP status codes, latency, headers, and payload bodies, subject to approved data-handling requirements
• Validate near-real-time inline checks and longer-running background verification/risk pipelines
• Verify data persistence, referential integrity, and correct linkage of related records and relationships
• Execute controlled replay suites and compare expected versus observed API behavior
• Correlate replay results with API schemas and network evidence produced by the Middleware SDET
• Document observable account/CID lifecycle behavior and downstream state changes for handoff
• Capture and archive test logs and evidence in a structured, retrievable format
• Collaborate with backend engineering teams to reproduce, isolate, and validate fixes for distributed-system defects
• Contribute to backend/middleware reliability test strategy, including failure-mode and chaos-style testing
• Maintain traceability between test evidence, defects, and system requirements
• Reconcile backend observations with frontend FSM and middleware/API evidence from earlier workstreams

• Strong experience of 5-8+ years in testing distributed systems and analyzing inter-service API behavior
• Hands-on experience with request payload tampering, fuzzing, or adversarial API testing techniques
• Understanding of layered defense architectures, including synchronous/inline validation and asynchronous/background verification processes
• Familiarity with testing data persistence and relational/hierarchical integrity in backend data stores
• Demonstrated discipline in test log archival, evidence capture, and structured documentation practices
• Solid understanding of backend/middleware architecture, failure modes, and system boundaries
• Familiarity with API testing tools and scripting for building custom fuzzing/tampering test cases
• Strong analytical and investigative skills for root-causing complex, systemic defects
• Experience executing controlled API replay or staging validation is strongly preferred
• Experience correlating API responses with observable application/account lifecycle states is preferred
• Experience supporting audit, compliance, or evidence-based reporting requirements is a plus

• Limitless Flexibility: Work on projects that fit your schedule
• Access to diverse content types
• Structured learning and career development opportunities
• Career paths that can lead to permanent roles
• Global community with real-time assistance from the Community Experience team
