Sr. Laser Welding Engineer

Join to apply for the Sr. Laser Welding Engineer role at Tesla

What To Expect

Tesla is seeking a highly motivated engineer to develop and scale up laser welding processes for Tesla’s high volume manufacturing lines. Specifically, this engineer is expected to be a Subject Matter Expert (SME) in the field of laser welding including metal welding (conductive, keyhole), transmission welding (plastics), laser ablation and in-line metrology. The engineer will work closely with Tesla’s internal Equipment Design, Product Design, Production and Quality Engineering teams, and coordinate cross-functional design activities with equipment vendors. This individual will assume ownership of the design and technical transfer of the laser welding tools to Tesla Operations, qualifying them for use with the highest standards of safety, quality, and output. This individual would be based in Markham, Ontario but would function as a global expert of these systems and some international travel will be required.

What You\'ll Do

• Lead development of innovative laser welding processes from proof-of-concept to full-scale production, including metals (conductive / keyhole modes), plastics (transmission welding), and hybrid joining techniques
• Conduct Design of Experiments (DOE) to optimize parameters (e.g., power, speed, focus) and perform sensitivity studies for robust, high-yield processes
• Select and integrate laser welding hardware (fiber, CO2, disk lasers) with external vendors, ensuring alignment with Tesla’s performance and scalability goals
• Develop in-line and offline metrology systems for real-time quality monitoring and post-process validation
• Serve as the subject matter expert (SME) for laser welding, guiding technical decisions including laser safety design and Design for Manufacturability (DFM)
• Support equipment qualification and ramp-up to high-volume production, troubleshooting defects, downtime, or scale-up challenges
• Develop alternate attachment methods (e.g., ultrasonic welding, resistance welding, adhesive bonding, swaging, crimping, press-fit) when laser welding is suboptimal
• Drive continuous improvement through data analysis, root cause investigations, and cross-functional collaboration
• Communicate technical findings effectively to peers, leadership, and external partners
