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 robust 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.

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 vers
