Process Development Engineer, Laser Welding

What To Expect
We're seeking elite engineers to develop advanced manufacturing processes for next-generation battery cells — the beating heart of every Tesla product. These cells will help make clean energy more affordable and widespread, supporting our mission to speed up the shift to sustainable energy and abundance. 

 

In this role, you'll own and develop one or more laser welding processes for cell assembly. You will collaborate with teams from design, build & test equipment, quality, vendors, and others — to create fixtures, run experiments, measure, analyze, iterate, and validate. You'll turn parts into finished cell products that power real change. 

 

Expect a fast-paced environment with real challenges and tight deadlines, where your ideas matter and success depends on strong first principles problem-solving and teamwork. Our team values clear communication, understanding others' views, hands-on approach, and continuous learning. You'll work alongside experts, new talent, and leaders from across Tesla, growing your capabilities every day while staying focused on our shared goals. 

What You'll Do

Design and develop laser welding manufacturing processes starting at lab-scale to ultimately enable high-volume production of cell products with improved quality, reduced costs, and increased efficiency 

Hands-on engagement with manufacturing / test equipment and automation development 

Design and run experiments to identify key process parameters; optimize processes to improve process capability, quality, and yield; decrease cycle time

Use software tools to develop predictive insights into tool and process performance to unlock manufacturing performance and improve safety while reducing cost 

Work independently and with vendors to understand root cause of failures, propose design or component changes, equipment modifications, ultimately implement and validate process changes

Define, release, and maintain technical documentation including process specifications, manufacturing instructions, and PFMEA

Occasional travel to Tesla factories, satellite team sites, and suppliers (domestic / international as needed) 

What You'll Bring

Degree or equivalent experience in Mechanical Engineering, Engineering Physics, Mechatronics, or a related field

5 years of experience as a laser welding process engineer (process development, process capability, troubleshooting, testing & validation, data acquisition & analysis) 

Robust fundamentals in lasers, heat transfer, phase change, weldability of materials demonstrated application to solve thorny problems 

Demonstrated ability to design and execute experiments, analyze data, and apply structured problem-solving (DOE, FMEA, 5-Why)

Experience with evaluating a process for scalability and ultimately scaling the process into mass production

Hands-on experience with automated equipment, sensors, robots, PLCs, and material handling equipment

Proficiency with hands-on fabrication skills 

Proficiency in 3D CAD modeling (CATIA V5/V6 experience is a plus) 

Foundational knowledge in GD&T (proficiency is a plus) 

Great communication skills (interpersonal & technical); willingness to lead discussions with internal & external groups; a team-first attitude
