The role involves developing and owning wet clean and etch processes for various chip families at Terafab, a large semiconductor factory. Candidates should have extensive experience in wet processing and be prepared to work across multiple process domains in a hands-on capacity.

• Degree in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or related technical field, or equivalent experience
• 5+ years of hands-on wet etch process engineering experience in a semiconductor fab, especially <7nm in a logic, memory, or foundry environment
• Deep experience with wet bench qualification, wet clean process development, and process of record (POR) establishment at advanced nodes
• Proficiency with wet process metrology tools: particle counters, defect inspection, film thickness measurement, and surface analysis techniques
• Strong DOE skills and statistical analysis capability (JMP, Python, or R)
• Ability to work closely and proactively across lithography, etch, thin films, integration, and equipment engineering teams

• Develop and qualify wet etch and wet clean processes for critical applications including oxide, nitride, silicon, and metal layer removal
• Own bath chemistry formulation, concentration control, temperature management, and process window optimization for both isotropic and selective wet etch steps
• Develop and qualify post-etch and post-CMP wet clean processes including single-wafer spin clean, megasonic, and dilute chemical clean steps
• Qualify wet process tools from installation through production readiness, including bench qualification, process chamber seasoning, and particle/defect control
• Analyze processes from a first-principles, physics-based approach to understand and manipulate mechanisms, not just recipes
• Lead root cause analysis, establish inline metrology and SPC control strategies, and drive systematic yield improvement
• Support 24/7 manufacturing operations through rotations, on-call availability, and rapid response to critical production issues
• Drive next-generation wet chemistry formulations and process development

• Employees at Tesla are often offered day-one coverage with multiple medical options (some at $0 paycheck cost), dental/vision, company HSA contributions, a 401(k) match, and equity programs. Most roles also include paid time off and holidays, family-building support, employee assistance, commuter and childcare benefits, and access to discounts and wellness programs.
