Senior Mechanical Engineer: HV Power Electronics

About Lucid

At Lucid, we are creating exceptional mobility experiences through innovation to drive the world forward. Built on Lucid’s proprietary technology and software-defined vehicle architecture, our award-winning vehicles bring our “Compromise Nothing™” approach to the global automotive market. That means refusing to choose between performance and sustainability, design and engineering, ambition and integrity. In Lucid Air and Lucid Gravity, we have designed and built vehicles that have redefined their segments, combining exceptional range, performance, design, and expansive space in a single experience.

We achieve this through deep vertical integration, with design, engineering, and productionhappening in-houseacross our global offices andmanufacturingfacilities.Ourteamscomefromindustriesaround the world, united by a shared commitment to excellence.By refusing to settle, youcanhelpredefinewhat’spossible andshape the future of mobility.

About Us: We are at the forefront of electric vehicle innovation and we’re looking for a highly motivated Mechanical Engineer to join our team. If you are passionate about pushing the boundaries of technology and thrive on solving complex challenges, we want to hear from you.

Role Overview: As a member of our High Voltage (HV) Design team, you will lead the development of next-generation high voltage power electronics that directly impact vehicle charging performance, efficiency, cost, reliability, and customer experience across future Lucid vehicle platforms. You will investigate electro-mechanical challenges and implement innovative solutions. You will drive every stage of the process, from concept to production, and collaborate with cross-functional teams to create solutions that bolster Lucid’s engineering dominance in the EV world. If you’re the kind of person who sees a problem, develops a solution, and engineers an improvement no one’s asked for yet, then we want to talk with you!

We compromise nothing and heavily value first principles engineering. Our ideal candidate exhibits a can-do attitude, demonstrates excellence in their respective fields, and possesses the ability to adapt quickly within a fast-paced environment. They are always striving to push the envelope of what’s possible.

Responsibilities:

• Own The Design : Lead the mechanical architecture, packaging, integration, and validation of core power electronics systems, including onboard chargers, DC-DC converters, and HV junction boxes.
  • Managing every aspect of design engineering from concept to production and beyond.
  • Develop system-level solutions that balance electrical performance, mechanical robustness, manufacturability, cost, serviceability, and customer experience.
  • Lead supplier technical reviews, DFMEA reviews, tooling reviews, validation alignment, and production launch activities.
• Prototype & Test : Design, build, and test your prototypes
  • Define and support executing environmental, vibration, thermal shock, temperature cycling, ingress protection, durability, and mechanical qualification testing
  • Drive design changes based on test results and real-world feedback.
• Innovate & Optimize : Continuously optimize designs for cost and performance without sacrificing safety or reliability.

• Collaborate : Work closely with electrical engineers, quality assurance, manufacturing, and other cross-functional teams to ensure seamless integration of mechanical and electrical systems.

• Mentor : Provide technical guidance to junior engineers, lead internal design reviews, and drive engineering decisions through analysis, testing, and first-principles reasoning.

• Continuously Learn : Embrace new challenges and expand your engineering skills in a fast-paced, dynamic environment.

Qualifications:

• Ideally 3-6 years of relevant work experience but open to all levels of experience if paired with strong technical proficiency

• Rock-solid Mechanical Engineering fundamentals and a flair for creative problem-solving

• Experience packaging complex electromechanical assemblies with consideration for thermal, structural, electrical isolation, and manufacturability requirements.

• Experience developing liquid-cooled power electronics assemblies including cold plates, thermal interfaces, heat spreaders, and coolant sealing systems

• Strong understanding of high-voltage product design considerations, including insulation systems, creepage and clearance, grounding, shielding, and HV safety requirements.

• Strong 3D CAD skills, proficient with CATIA or similar software

• Strong knowledge of GD&T and Creepage & Clearance principles

• Proven Design for Manufacturing (DFM) and Design for Assembly (DFA) experience across injection molded plastics, sheet metal, die castings, busbars, gaskets, adhesives, and PCBA-integrated assemblies.

• Experience with Root Cause Analysis methods, such as 8D

Preferred:

• Experience with automotive engineering and product validation (environmental testing, shock/drop, etc)

• Experience designing high-voltage power electronic products such as onboard chargers, DC-DC converters, inverters, HV junction boxes, battery disconnect units, or similar electromechanical systems.

• Experience with FEA tools (Ansys or similar software) for structural and thermal analysis.

• Experience supporting APQP, PPAP, DFMEA, and production launch activities.

• Experience working directly with automotive suppliers and contract manufacturers.

Education:

• Bachelor’s or Master’s degree in Mechanical Engineering or a related discipline.

Location:

• Role is on-site at Lucid HQ in Newark, California
