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.

What We're Looking For

  • Sustained test-engineering responsibility on real aerospace or electromechanical systems, alongside military experience.

  • Strong electrical bench skills with oscilloscopes, logic analyzers, power supplies, digital multimeters, and harness fabrication.

  • Proficiency in Python or scripting for test automation, including building custom tools.

  • Experience debugging across firmware and electrical systems, and conducting performance, reliability, and safety testing.

  • Clear written communication, including failure reports and root cause analysis.

  • Background in robotics, defense, aerospace, or related work involving electromechanical products and hands-on test setups.

  • Familiarity with design for manufacturability and production testability.

  • Experience with HIL or SIL, relevant aerospace or defense standards, environmental or high-voltage testing, or export-controlled systems is a plus.

  • U.S. Person status is required due to access to export-controlled information.

Compensation & Benefits

Base salary: $130,000 to $170,000 annually. Visa sponsorship is not available.

Location

On-site in San Francisco, California, United States. Regular field testing is part of the role.
