Avionics Hardware Design Engineer III – Lunar Permanence

Responsibilities

• Develop comprehensive test strategies, test methodologies, and test fixtures — including design of supporting test hardware — for power subsystem hardware from component level through integrated vehicle testing
• Design, develop, and deliver test support hardware including test cards, breakout boards, and fixture circuits to enable safe and efficient validation of power subsystem assemblies
• Execute and supervise validation campaigns including acceptance testing and Thermal Vacuum (TVAC) testing
• Ensure proper test execution, data collection, and system requirement verification
• Develop and maintain automated test scripts for EGSE and vehicle power sequencing
• Troubleshoot electrical failures, identify root causes, and implement corrective actions
• Coordinate and integrate interfacing subsystems with the power subsystem
• Support design risk analyses, failure modes effects and criticality analyses (FMECA), and design for test activities
• Effectively communicate development status, risks, and challenges to management

• Bachelor of Science in Electrical Engineering, or related field
• 5+ years of experience in electrical engineering, with a primary focus in both hardware test and validation and electrical circuit design
• Understanding of power electronics hardware development, such as developing high‑voltage switching
• Experience developing test plans, test procedures, and acceptance test procedures for high‑voltage applications
• Experience with automated test scripting (Python, LabVIEW, or equivalent)
• Understanding of power systems hardware including power distribution, DC‑DC converters, power integrity, and power sequencing
• Experience with mixed‑signal circuit design, including analysis, simulation, test, troubleshooting, and part selection
• Familiarity with many of the following parts and their usage: power supplies (linear, LDO, DC/DC), MOSFETs, op‑amps, ADCs, and DACs
• Knowledge of common communication methods such as RS422, RS485, SPI, LVDS, or similar protocols
• Desire to work hands‑on, both independently and as part of a team, throughout the development and test phases of the electronic assembly product lifecycle.
