About the Job

Requirements

A degree in Electrical, Mechanical, Mechatronics, Manufacturing, or Materials Engineering, or equivalent experience.
At least 3 years of experience industrializing, manufacturing, or qualifying electromechanical or electromagnetic devices such as contactors, relays, solenoids, actuators, motors, or switches.
Hands-on fluency with coil winding, contact welding, magnetic circuit stamping, plating, overmolding, potting, hermetic sealing, and functional testing.
Working knowledge of contact physics, including arcing, bounce, welding, and material transfer; electromagnetic actuation, including force versus air gap, coil heating, and residual magnetism; and high-voltage insulation and creepage.
Proven ownership of APQP/PPAP or equivalent, PFMEA, control plans, MSA, SPC, and process capability (Cpk) for electrical and mechanical special characteristics.
Ability to read drawings, GD&T, and electrical specifications; challenge a datasheet; and write clear process or test requirements.
Structured problem-solving experience using 8D, FTA, DOE, and 5-Why; Excel proficiency is required.
Experience auditing manufacturing quality systems such as IATF 16949, VDA 6.3, and ISO 9001, and driving sub-tier control.
Clear, direct written and verbal communication with suppliers and internal engineering, including on the factory floor.

Responsibilities

Own industrialization of electromechanical and electromagnetic devices from advanced development through PPAP or production part approval and stable mass production, including high-voltage contactors and relays, solenoids, actuators, pyro disconnects, switches, small motors, and related electromagnetic assemblies.
Plan, organize, and execute supplier process development for stamping and forming of magnetic circuits and contact systems; coil winding and termination; resistance and laser welding; plating; overmolding and potting; hermetic sealing; and final functional testing.
Lead Design for Manufacturability (DFM) and Design for Assembly (DFA) with Design, Reliability, and suppliers, and resolve air-gap, contact-force, weld, creepage/clearance, and tolerance stack-up issues before tooling kickoff.
Define and freeze process flows, PFMEA, control plans, and special characteristics, including contact resistance, bounce, dielectric withstand, coil resistance, pull-in/drop-out voltage, weld splash, leak rate, and insulation resistance.
Qualify supplier manufacturing lines, including equipment capability, MSA, SPC on critical dimensions and electrical parameters, poka-yoke, traceability, and end-of-line functional, hipot, and leak-test coverage.
Drive APQP deliverables and PPAP or equivalent for first-time-right launch; own capacity models, OEE, yield, and ramp plans aligned with production cadence; and manage engineering changes, second-source qualification, and localization industrialization without interrupting production.
Audit suppliers against IATF 16949, VDA 6.3, and Tesla process requirements; identify and close gaps in process control, change management, and sub-tier suppliers for contacts, magnets, coils, plastics, and platings.
Lead debugging when yield, reliability, or delivery issues arise; conduct structured problem solving using 8D, FTA, DOE, and Ishikawa; implement permanent countermeasures; travel to supplier sites and factories; and make technical decisions on the factory floor.
Translate application conditions such as inrush, inductive load, vibration, thermal cycling, salt, and high-voltage isolation into supplier process windows and validation plans, using ISO 16750, LV 124/VW 80000, AEC-Q200, and IEC/UL standards where applicable.
Partner with Purchasing, Quality, NPI, and Manufacturing to achieve cost, quality (PPM), and delivery goals; challenge suppliers on cycle time, scrap, automation, and material utilization.

Desired Qualifications

Automotive, industrial power, or high-reliability electronics experience.
High-voltage contactor, pyro-fuse, traction-inverter, or energy-product component experience.
Six Sigma or CQE qualification.
JMP, Minitab, or Python experience.
Mandarin, German, Korean, or Japanese language ability.

Job Description

Tesla’s mission is to accelerate the world’s transition to sustainable energy. That mission depends on parts that switch, actuate, and isolate at high voltage, high current, and high cadence. The Supplier Industrialization Engineer (SIE) for Electromechanical and Electromagnetic Devices is the manufacturing owner for this commodity. You sit between Design, Purchasing, and the supplier. You are the resident process expert, the NPI lead at the factory, and the person who does not accept “the line has always run this way.” You will industrialize contactors, relays, solenoids, actuators, pyro disconnects, switches, and small electromagnetic machines from first samples through mass production. You will spend real time on supplier floors such as welding cells, winding lines, plating, overmold, and end-of-line test. You will make on-the-spot decisions that protect Tesla’s launch and the customer. The pace is high. The work is first principles, data, and process control, not slideware.

Job Responsibilities

Own industrialization of electromechanical and electromagnetic devices from advanced development through PPAP / production part approval and stable mass production — including high-voltage contactors and relays, solenoids, actuators, pyro disconnects, switches, small motors, and related electromagnetic assemblies
Plan, organize, and execute supplier process development: stamping and forming of magnetic circuits and contact systems; coil winding and termination; resistance / laser welding; plating; overmolding and potting; hermetic sealing; and final functional test
Lead Design for Manufacturability (DFM) and Design for Assembly (DFA) with Tesla Design, Reliability, and the supplier. Close air-gap, contact-force, weld, creepage/clearance, and tolerance stack-up issues before tooling kickoff
Define and freeze the process flow, PFMEA, control plan, and special characteristics (contact resistance, bounce, dielectric withstand, coil resistance, pull-in / drop-out voltage, weld splash, leak rate, insulation resistance)
Qualify manufacturing lines at the supplier: equipment capability, MSA, SPC on critical dimensions and electrical parameters, poka-yoke, traceability, and end-of-line functional / hipot / leak test coverage
Drive APQP deliverables and PPAP (or Tesla equivalent) to first-time-right launch. Own capacity models, OEE, yield, and ramp plans that match Tesla’s production cadence. Manage engineering change, second-source, and localization industrialization without interrupting Tesla production
Audit suppliers against IATF 16949, VDA 6.3, and Tesla process requirements. Identify gaps in process control, change management, and sub-tier (contacts, magnets, coils, plastics, platings) and close them with the supplier
Lead debug when yield, reliability, or delivery breaks. Run structured problem solving (8D, FTA, DOE, Ishikawa) and implement permanent countermeasure. Travel to supplier sites and Tesla factories and make technical decisions on the floor
Translate Tesla application conditions (inrush, inductive load, vibration, thermal cycling, salt, HV isolation) into supplier process windows and validation plans (ISO 16750, LV 124 / VW 80000, AEC-Q200, IEC / UL where applicable)
Partner with Purchasing, Quality, NPI, and Manufacturing to hit cost, quality (PPM), and delivery. Challenge the supplier on cycle time, scrap, automation, and material utilization — first principles, not tradition

Job Requirements

Hands-on fluency with the processes that actually make these parts: coil winding, contact welding, magnetic circuit stamping, plating, overmold, potting, hermetic seal, and functional test

Working knowledge of contact physics (arcing, bounce, welding, material transfer), electromagnetic actuation (force vs. air gap, coil heating, residual magnetism), and insulation / creepage at high voltage

About the Company

Tesla

Makes electric cars, robotaxis and grid batteries

Tesla makes electric cars and batteries that store power for homes and utilities, and it develops self-driving software and humanoid robots. In 2023, its Model Y became the first electric vehicle to rank as the world's best-selling car. Buyers order the Model 3 sedan, Model Y SUV, or Cybertruck pickup directly from Tesla instead of through dealers, and they charge on its Supercharger fast-charging network. It also sells Megapack and Powerwall batteries, runs a robotaxi service, and charges drivers a monthly fee for self-driving software that still needs their supervision. Tesla was founded in 2003, with Elon Musk as its lead early investor and a recognized co-founder, and it is based in Austin, Texas.
