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. The ideal
candidate has solid distributed-systems and API-testing experience
and maintains disciplined technical evidence capture and
traceability. This role is not intended to perform unrestricted
adversarial testing. Testing activities will be limited to approved
staging environments and pre-approved benign scenarios. Project
Details Title: Senior SDET Rate: $13.5/hr Start Date: 19th October
Duration: 5 Weeks Commitment : 33 Hours per Week Location: India
(Remote) Job Type: Freelance Responsibilities 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 behavior of near-real-time inline checks
(evaluated within milliseconds at the gateway) as distinct from
longer-running background verification/risk pipelines (evaluated
over minutes to hours), confirming each layer of defense behaves as
expected Verify data persistence, referential integrity, and
correct linkage of related records/relationships written by backend
services during processing Execute controlled replay suites and
compare expected versus observed
