Sr. Test Engineer (Inverter)

About the role

Join Lucid Motors to lead the development and maintenance of automated test systems for electric vehicle power electronics. This role focuses on ensuring the performance, safety, and reliability of high-voltage inverters through rigorous in-process and end-of-line testing. You will collaborate with various engineering and production teams to deliver robust and scalable test solutions.

Key facts

What you'll do

• Act as the manufacturing test authority for traction inverter validation, reviewing and approving test specifications and change requests from design engineering.
• Analyze and provide feedback on test sequences, limits, cycle time, process flow, and failure handling for inverter end-of-line and sub-assembly test stations.
• Design and take ownership of test system hardware, including system layout, cabinet and rack design, high-voltage/low-voltage routing, connectors, shielding, grounding, and thermal considerations for high-power switching electronics.
• Develop modular and scalable test applications with clear operator interfaces, managing parameters, sequencing, fault messaging, and data logging.
• Implement databases for managing test parameters, serial-level results, traceability, and correlation with manufacturing and quality systems.
• Define device under test (DUT) handling, fixturing, and electrical/mechanical interfaces for test stations, including automated high-voltage connections and safety interlocks.
• Work with controls engineers to integrate test applications with station PLCs, dynos or load systems, cooling systems, and material handling equipment, including responses to electrical, thermal, and safety-critical failures.
• Lead the sourcing, RFQs, supplier selection, build tracking, and technical oversight for externally supplied inverter test equipment.
• Develop and execute commissioning and validation plans for test systems, including GR&R, red-rabbit units, fault injection, and simulation of electrical, thermal, and communication failures.
• Launch inverter test systems into production and provide on-floor support during ramp-up, focusing on limit tuning, yield improvement, and false-fail reduction.
• Train maintenance and operations teams on test station operation, error recovery, and safe troubleshooting of high-voltage power electronics.
• Partner with factory data and analytics teams to enable test data visualization, yield tracking, efficiency trends, and long-term quality monitoring.

Requirements

• Bachelor's Degree in Controls Systems Engineering, Electrical and Controls Engineering, or Automation and Control Engineering.
• At least 5 years of professional experience.
• 5 to 8 years of experience developing and launching automated test equipment in high-volume manufacturing environments.
• Direct experience testing EV traction inverters or high-power power electronics in a manufacturing or production setting.
• Strong understanding of inverter architectures, power stages, gate drivers, DC-link capacitors, current sensing, and thermal management.
• Hands-on experience with inverter end-of-line and in-process testing, such as functional power testing, PWM validation, phase current measurement, switching performance, efficiency testing, isolation resistance, and hipot testing.
• Detailed knowledge of high-voltage and high-current electrical components, connectors, cables, shielding, and grounding best practices.
• Ability to design electrical schematics.
• Experience developing test hardware using National Instruments platforms such as PXI, cDAQ, or cRIO.

Skills & tools

• Software development experience with NI LabVIEW, NI TestStand, Python, or MATLAB.
• Working knowledge of automotive communication protocols including CAN, CAN-FD, LIN, and Automotive Ethernet, including inverter diagnostics and calibration interfaces.
• Proficiency using electrical test equipment such as power supplies, electronic loads, oscilloscopes, DMMs, power analyzers, and inverter or power electronics diagnostic tools.
• AutoCAD, EPLAN, or equivalent tools for electrical schematics.
• Strong organizational skills to manage multiple test stations, suppliers, and launch timelines.
• Clear and professional communication skills for cross-functional collaboration.

Nice to have

• Experience interfacing test systems with PLCs and industrial networks such as Ethernet/IP or OPC-UA.
