Test Engineer, R&D

Your tasks

Build test infrastructure for defense robotics products, spanning automation, hardware harnesses, simulation, and hardware-in-the-loop environments. Working across hardware, software, and electrical teams, you will own testing from design and execution through analysis and failure investigation, helping products advance from prototype to production.

• Design and execute end-to-end test procedures, including setup, operation, data collection, teardown, analysis, and failure reports.
• Wire test electronics and build 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.
• Work with embedded, electrical, and mechanical engineers to reproduce issues, validate fixes, and prevent regressions.
• Create test plans, acceptance criteria, and readiness gates as products move toward 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, with increased testing around sprint demos and milestones.

Requirements

• 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 practical test tools.
• Demonstrated debugging across firmware and electrical systems, including power rails.
• Experience integrating performance, reliability, and safety testing.
• Background testing real electromechanical products in robotics, defense, aerospace, or a related field.
• Familiarity with design for manufacturability and production testability.
• Clear written communication, especially for failure analysis and root cause findings, and the ability to collaborate across engineering disciplines.
• Experience with HIL or SIL, military or aviation 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.
