Manufacturing Engineer, Back-End Cell Assembly

About the role

• Manufacturing Engineer, Back-End Cell Assembly | Tesla (Manufacturing)
• Location: AUSTIN, Texas | Req ID: 285907 | Job Type: Full-time
• What to Expect

Gigafactory Texas is seeking a strategic, highly motivated Manufacturing Development Engineer to help define and scale Tesla’s next-generation 4680 cell assembly. You will lead the design, development, and optimization of advanced manufacturing equipment and systems, driving long-term architecture for scalability, flexibility, reliability, quality, speed, and cost. You’ll collaborate closely with Design, Process, Production, Controls, R&D, and global OEM/automation partners, provide technical mentorship, and champion innovative, high-impact approaches that push battery cell manufacturing forward.

What You'll Do

• You will own end-to-end Design For Manufacturing (DFM), leading change control, process qualification, commissioning, and formal handovers for new lines, first-of-kind and duplicate equipment, retrofits, and optimization projects. Including Prototyping/FAT/SAT/GR&R/Cpk sign-off, and delivering required packages (FMEA, BOM, LOTO, SOPs, build-as-print), remain engaged post-handover for change management, OEE ramps, fleet landing plans, vendor qualification, and escalation through Change Control Boards
• Deploy, validate, and continuously optimize automated cell assembly equipment for press-fit/swaging, ultrasonic welding, laser welding, helium leak testing, hi-pot testing, and X-ray inspection. Drive process characterization, root-cause analysis (5 Whys, 8D, DMAIC), DOE, SPC, GD&T, and statistical validation to achieve process capability, high yield, and low downtime
• Partner cross-functionally with R&D, Ramp, Quality, Maintenance, Automation, and vendors to introduce new cell designs/materials, standardize handover procedures, and close outliers. Optimize cell handling, vision inspection, and joining systems for speed, precision, and repeatability
• Design and integrate advanced automation (PLCs, motion control, real-time data, error-proofing), sophisticated vision systems (Keyence/Cognex), and pneumatic/mechanical/electrical systems (Bluebeam/AutoCAD/Eplan). Develop safety solutions and culture aligned with OSHA, ISO, TUV, NFPA-70E, and IEC standards
• Lead multidisciplinary projects (NPI, CAPA, RCA, OCAP) that integrate automation, predictive analytics, and quality systems (PFMEA/DFMEA, risk assessments). Mentor teams, apply Agile/OKRs, and drive improvements in safety, people, accuracy, rate, and cost
• This role sits at the intersection of process development, equipment qualification, and production ramp, giving you direct influence on how new and existing systems come online and stay capable

What You'll Bring

• Degree or Equivalent Experience in Mechanical, Manufacturing, Chemical, Materials, or Electrical Engineering (or equivalent experience) plus 5+ years in process/equipment development, preferably in lithium-ion batteries/energy storage, electronics, medical devices, automotive, or hermetic packaging. Hands-on lithium-ion cell design, assembly, testing, failure analysis, and R&D-to-production transfer. Demonstrated application of engineering fundamentals to manufacturing scale-up, including dry-room operations with dew-point control, ISO 7/8 cleanroom particle/contamination management, and electrolyte handling at ppb moisture levels
• Proven skills in DFM (including cell design input on fill ports and sealing features), equipment/tooling specification/qualification/validation (IQ/OQ/PQ, FAT/SAT), yield/cost/cycle-time optimization, automation integration, project management, and cross-functional collaboration with cell design, electrochemistry, quality, production, EHS, and suppliers
• Strong safety/EHS knowledge for flammable/corrosive electrolytes, high-voltage, pressure systems, automation interlocks and PPE. Proficiency with CAD (SolidWorks/AutoCAD/Eplan), GD&T, fixture/tooling design, FEA (thermal/pressure/deformation), statistical tools (DOE, SPC, Cpk/Ppk, Minitab/JMP), PFMEA, control plans, MSA/GR&R, Lean/Six Sigma, MES/Industry 4.0 data systems with QR/barcode traceability
• Electrolyte high-pressure filling (vacuum evacuation, precise dosing, inert-gas wetting, temperature/pressure profiles, and homogeneous distribution without overflow or dry spots). Cell weight measuring (inline gravimetric verification of fill mass with high-precision scales, SPC, GR&R, and rejection logic)
• Press fitting (hermetic sealing of fill ports via high-hardness components with force/displacement monitoring, leak-tightness, and post-press verification). Washing systems at controlled temperature and high pressure (aqueous/solvent sprays for residue removal, drying, and wastewater recovery)
• Vision inspection using 2D/3D systems (high-res cameras, laser triangulation/structured light, AI-assisted defect detection for dents, scratches, misalignment, seals, and labels). Hipot testing (AC/DC dielectric withstand for insulation failures, internal shorts, and leakage current with SPC)
• Leadership experience guiding mid-to-large multidisciplinary teams, mentoring others, and delivering company-wide impact. Comfort with Agile, OKRs, and high-performing, fast-changing environments. Strong problem-solving, decision-making, material compatibility knowledge (LiPF6-based electrolytes, Al/SS/Cu, polymers, sealing materials), and ability to manage multiple priorities under shifting requirements while closing the loop with formation, aging, and reliability
