Staff Facilities Design Engineer, Wet Mechanical Systems, Solar Manufacturing

What to Expect Project Crystal is Tesla's multi-GW solar manufacturing program spanning polysilicon refining, monocrystalline ingot growth, wafering, and high-efficiency cell manufacturing. We are building facilities where mechanical utilities are process-critical — not afterthought building services.

As a Senior or Staff Facilities Design Engineer focused on Wet Mechanical Systems, you will own the design direction for liquid-side utility plants and distribution that keep process tools running: chilled water, process heating water, cooling towers, industrial water, and closely related wet systems. You will translate process equipment utility demand into reliable, efficient, maintainable plant and distribution designs, and lead external design partners to deliver construction-ready packages.

What You'll Do Own wet mechanical basis of design (BOD), design criteria, and system architecture for Crystal manufacturing buildings (pilot through scale)

Own chilled water (including low-temperature process CW), process heating / hot water, cooling towers, chillers, heat exchangers, pumps, primary/secondary distribution, industrial process water, domestic water interfaces, sanitary and process waste, safety shower/eyewash systems

Convert process equipment utility matrices (EQM), vendor datasheets, and manufacturing layouts into plant capacity, redundancy (e.g., N+1), diversity, and distribution strategies

Lead and technically direct A&E / design firms; review calculations, P&IDs, one-lines, layouts, specifications, and IFC packages; drive quality and Tesla design standards

Identify and specify long-lead wet mechanical equipment (chillers, towers, pumps, heat exchangers, tanks) and support procurement technical evaluation

Partner tightly with Dry Mechanical, Plumbing, Process (UPW/DI, wastewater, bulk chemicals), Electrical, Controls, Architecture, Structural, Fire Protection, EHS/Process Safety, Tool Install, Construction, and Commissioning

Support construction RFIs, shop drawing review, field coordination, and commissioning planning for wet systems

Design for energy efficiency, operability, maintainability, and production uptime; document assumptions and residual risks clearly

Mentor junior engineers and set technical bar for wet mechanical design quality across the program (Staff expectation)

What You'll Bring Bachelor's Degree in Mechanical Engineering, or equivalent experience

8-12+ of experience years with demonstrated technical leadership of complex industrial mechanical design

Proven ownership of industrial wet mechanical / process cooling design packages from BOD through construction documents (not CAD-only or pure field ops)

Hands-on design experience with central utility plants and process chilled/heating water systems for advanced manufacturing, semiconductor, solar, battery, specialty chemical, or similar

Strong working knowledge of hydronic system design: pumps, control valves, expansion, water treatment interfaces, pipe materials for industrial service, insulation, and instrumentation basics

Ability to read and challenge process equipment utility data and vendor packages; comfortable with load calculations, diversity, and redundancy tradeoffs.

Experience directing or QC'ing external A&E deliverables

Working knowledge of applicable codes and standards (e.g., ASME B31.3, ASHRAE, IPC/UPC as applicable, local industrial codes)

Excellent written and verbal communication; ability to present technical recommendations to program leadership
