Responsibilities

Own test strategy & architecture. Define multi-layer test plans (unit / integration / system / E2E) for services, devices, and production cells; identify risk, coverage gaps, and escape routes before they happen.

Build and evolve frameworks. Write and maintain Go / Java test suites; extend / replace frameworks as needed; create reusable libraries, emulators, and fixtures for SITL / HITL.

Make CI / CD enforce quality. Integrate tests into the development pipeline with high levels of automation.

Lead integration cadences. Orchestrate recurring integration events; track results in GitHub / Jira; translate failures into crisp, prioritized defects and action plans.

Operate on the line. Bring up simulations and physical rigs; commission systems; monitor uptime and telemetry; apply safe runtime mitigations using existing tools when possible

Instrument for truth. Define reliability metrics (e.g., pass rates, MTBF / MTTR, SLOs), build dashboards / alerts, and drive root-cause analysis until issues are eliminated, not just mitigated.

Raise the bar across teams. Mentor engineers on testability, fault injection, and observability; influence designs and roadmaps toward the highest-ROI quality improvements

Close the loop. Land small, surgical fixes when it’s faster than hand-off; document learnings so they become standard practice.

Requirements

5–8+ years hands-on building tests and frameworks for complex systems (services + devices / robots / industrial control).

Proficient in Go , Java , and / or Rust ; Proficient in GitHub workflows, Jira, Docker / containers, and modern CI pipelines.

Proven experience with SITL / HITL , emulators, or robotics / industrial simulation environments.

Comfortable triaging high-severity issues in production-like environments and turning them into engineering priorities.

Clear, concise communicator who chases flakiness to ground truth.

Eagerness to grow a team over time as deployments ramp

Bonus Qualifications

Deep understanding of static analysis, fuzzing, chaos testing , and change-impact analysis.

Knowledge of OPC UA, MQTT, Modbus, PLCs, Ignition , or other industrial protocols and SCADA / MES contexts.

Advanced GitHub Actions or other pipeline-automation chops

Experience with reliability metrics and on-call readiness for manufacturing systems

Join the mission. We'll handle the move.

Exceptional talent shouldn't be bound by geography. If you're ready to relocate to Dallas, TX and join us in reindustrializing America’s defense backbone, we'll make it easy—and for those who move quickly, additional incentives may be available.
