Sr. Mechanical Engineer II, Vehicle HV Distribution

Employer description

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 production happening in-house across our global offices and manufacturing facilities. Our teams come from industries around the world, united by a shared commitment to excellence. By refusing to settle, you can help redefine what’s possible and shape 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 the High Voltage Design team, you will lead the development of next-generation high-voltage distribution systems including HV connectors, vehicle harnesses, charge ports, and associated electromechanical components. You will be responsible for architecture development, component design, vehicle integration, validation, and launch of critical HV systems that enable safe and reliable power delivery across Lucid vehicle platforms. 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: Take ownership of in-house HV connector designs, routing and optimization of HV harnesses, and related components for next-generation vehicle platforms, ensuring successful implementation from concept to production and beyond 

• 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 designing and packaging vehicle wiring harnesses with consideration for routing, retention, serviceability, EMC, thermal environments, crash requirements, and manufacturing constraints. 

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

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

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

Preferred: 

• Experience with automotive engineering 

• Experience with battery disconnect units, HV junction boxes, and vehicle power distribution architectures 

• Strong understanding of high-voltage design principles including creepage and clearance, touch-safe architectures, HVIL systems, shielding, grounding, insulation systems, and electrical safety requirements.
