## Description

### About the Role

Build test infrastructure for a defense technology company developing autonomous electromechanical systems. Working with a lean engineering team across hardware, software, and electrical disciplines, you will support products from prototype through production.

### What You'll Do

- Design and execute end-to-end test procedures, including setup, operation, data collection, teardown, analysis, and failure reports.

- Build test electronics, harnesses, instrumentation setups, and fixtures.

- Develop Python-based automated test procedures and custom test tools.

- Debug firmware, power rails, and electrical systems to identify root causes.

- Partner with embedded, electrical, and mechanical engineers to reproduce issues, validate fixes, and prevent regressions.

- Define test plans, acceptance criteria, and readiness gates as products progress from prototype to production.

- Build hardware-in-the-loop and software-in-the-loop test environments.

- Support design for manufacturability and production readiness with hardware teams.

- Follow safety procedures during high-power and high-voltage testing.

- Conduct regular field tests, increasing testing activity around sprints, demos, and milestones.
