Position Overview

The Senior Test Engineer – Inverter will be instrumental in developing, launching, and sustaining automated test systems for Lucid’s electric traction inverter manufacturing lines. This critical role focuses on in-process and end-of-line (EOL) testing of high-voltage inverters to validate functional performance, safety, efficiency, and long-term reliability. The engineer will collaborate closely with cross-functional teams, including Design Engineering, Controls, Quality, Production, and external equipment suppliers, to deliver robust, scalable, and data-driven test solutions that align with Lucid’s high standards of excellence.

Key Responsibilities

• Test Specification and Validation: Review and approve inverter test specifications and change requests from design engineering, serving as the manufacturing test authority for traction inverter validation.
• Test System Optimization: Analyze and provide feedback on test sequences, limits, cycle time, process flow, and failure-mode handling for inverter EOL and sub-assembly test stations to enhance efficiency and reliability.
• Hardware Design and Development: Design and own test system hardware for inverter testing, including system layout, cabinet and rack design, high-voltage/low-voltage routing, connectorization, shielding, grounding, and thermal considerations for high-power switching electronics.
• Test Application Development: Develop modular and scalable test applications with intuitive operator interfaces, incorporating parameter management, test sequencing, fault messaging, and comprehensive data logging.
• Database Management: Implement and maintain databases to manage inverter test parameters, serial-level results, traceability, and correlation with manufacturing and quality systems for enhanced data-driven decision-making.
• Fixture and Interface Design: Define device-under-test (DUT) handling, fixturing, and electrical/mechanical interfaces for inverter test stations, including automated high-voltage connections and safety interlocks to ensure operational integrity.
• System Integration: Collaborate with controls engineers to integrate test applications with station PLCs, dynamometers or load systems, cooling systems, and material handling equipment, ensuring robust responses to electrical, thermal, and safety-critical failure modes.
• Supplier and Equipment Management: Lead the sourcing, RFQs, supplier selection, build tracking, and technical oversight for externally supplied inverter test equipment to ensure alignment with project timelines and quality standards.
• Commissioning and Validation: Develop and execute commissioning and validation plans for inverter test systems, including Gage Repeatability and Reproducibility (GR&R), red-rabbit unit testing, fault injection, and simulation of electrical, thermal, and communication failures.
• Production Launch Support: Launch inverter test systems into production and provide on-floor support during ramp-up phases, including limit tuning, yield improvement initiatives, and reduction of false-fail occurrences.
• Training and Knowledge Transfer: Train maintenance and operations teams on inverter test station operation, error recovery, and safe troubleshooting of high-voltage power electronics to ensure operational readiness.
• Data Analytics and Reporting: Partner with factory data and analytics teams to enable inverter test data visualization, yield tracking, efficiency trend analysis, and long-term quality monitoring to drive continuous improvement.

Required Qualifications

To qualify for this role, candidates must possess a Bachelor’s Degree in Controls Systems Engineering, Electrical and Controls Engineering, or Automation and Control Engineering, along with a minimum of five years of professional experience. Additionally, candidates should have 5 to 8 years of hands-on experience developing and launching automated test equipment in high-volume manufacturing environments, with a proven track record in test system design, validation, and deployment. Strong collaboration skills, attention to detail, and a commitment to excellence are essential for success in this dynamic and innovative role.
