What this role actually is
Test and integration engineers make sure systems are evaluated in structured, repeatable ways before people trust them. The role is about test design, instrumentation, automation, issue capture, and documenting behavior clearly enough that others can act on the results.
Identifying the right signal
Build a flight-style embedded computer that logs sensors, publishes telemetry, and supports repeatable validation.
Create a test bench that injects signals, runs automated scenarios, and records pass/fail behavior against expectations.
Build a software-defined radio or RF telemetry link with disciplined measurement, logging, and environment-aware testing.
Build a telemetry stack with primary and backup sensing paths, error logging, and a clear validation story around degraded behavior.
