Sr. Test Engineer (Inverter)

About Lucid Motors

Lucid Motors focuses on creating mobility experiences through innovation, leveraging proprietary technology and a software-defined vehicle architecture. The company's approach emphasizes performance, sustainability, design, and engineering, as demonstrated in its Lucid Air and Lucid Gravity vehicles. Lucid operates with deep vertical integration, managing design, engineering, and production in-house across global offices and manufacturing facilities.

About the Role

The Sr. Test Engineer (Inverter) will lead the development, launch, and sustainment of automated test systems for Lucid’s electric traction inverter manufacturing lines. This full-time role is critical for EV power electronics production, focusing on in-process and end-of-line (EOL) testing of high-voltage inverters to ensure functional performance, safety, efficiency, and long-term reliability. The engineer will collaborate with Design Engineering, Controls, Quality, Production, and external equipment suppliers to deliver robust, scalable, and data-driven inverter test solutions. Candidates should have 5-10 years of relevant experience.

Key Responsibilities

• Review and approve inverter test specifications and change requests from design engineering, serving as the manufacturing test authority for traction inverter validation.
• Analyze and provide feedback on test sequences, limits, cycle time, process flow, and failure-mode handling for inverter EOL and sub-assembly test stations.
• Design and manage test system hardware for inverter testing, including system layout, cabinet and rack design, HV/LV routing, connectorization, shielding, grounding, and thermal considerations for high-power switching electronics.
• Develop modular and scalable test applications with clear operator interfaces for inverter testing, encompassing parameter management, test sequencing, fault messaging, and data logging.
• Implement databases to manage inverter test parameters, serial-level results, traceability, and correlation to manufacturing and quality systems.
• Define DUT handling, fixturing, and electrical/mechanical interfaces for inverter test stations, including automated HV connections and safety interlocks.
• Collaborate 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 failure modes.
• Lead sourcing, RFQs, supplier selection, build tracking, and technical oversight for externally supplied inverter test equipment.
• Develop and execute commissioning and validation plans for inverter 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, including limit tuning, yield improvement, and false-fail reduction.
• Train maintenance and operations teams on inverter test station operation, error recovery, and safe troubleshooting of high-voltage power electronics.
• Partner with factory data and analytics teams to enable inverter test data visualization, yield tracking, efficiency trends, and long-term quality monitoring.

Experience and Qualifications

This role requires 5-10 years of experience in a relevant field, with a focus on manufacturing test engineering for power electronics, specifically inverters. Candidates should possess a strong understanding of high-voltage systems and automated test methodologies.

Working Environment

The Senior Manufacturing Test Engineer will work within a vertically integrated environment, collaborating with various internal teams such as Design Engineering, Controls, Quality, and Production, as well as external equipment suppliers. The role involves hands-on work with manufacturing lines and test systems.
