Sr. Process Engineer, Lithography, Terafab

| Job Category | Terafab | | Location | Austin, Texas | | Req. ID | 267824 | | Job Type | Full-time |

What to Expect

We are building Terafab, a vertically integrated semiconductor factory at an unprecedented scale. The facility houses logic, memory, packaging, test, and lithography mask production under one roof, optimized for rapid iteration and maximum compute density per square foot.

Process engineering is where Terafab technology gets built, atom by atom, and lithography will define the limit of what we can build. You will develop and own patterning processes across three distinct chip families: edge-inference processors, space-hardened chips for orbital satellites, and high-bandwidth memory.  With mask production in-house, you'll have unprecedented feedback loops to co-optimize reticle and scanner strategies.

You should have deep expertise in optical lithography, but be ready to work across core process domains such as etch, metrology, and film deposition as integration evolves. This is a highly hands-on role at one of the most ambitious fab programs in the world.

What You’ll Do

• Develop and qualify EUV and ArFi resist processes, exposure parameters, and coat/develop optimization for critical layers

• Qualify scanners (EUV and DUV) from installation through production readiness, including dose-focus matrices, CDU, and overlay

• Own in-house mask shop process development (resist, etch, inspection, repair) and co-optimize reticle-scanner strategies using tight feedback loops

• Establish overlay and registration control strategies, scanner-to-scanner matching, and APC loop integration

• 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 lithography materials and process development

What You’ll Bring

• Degree in Chemical Engineering, Materials Science, Electrical Engineering, Physics, or related technical field, or equivalent experience

• 5+ years of hands-on lithography process engineering experience in a semiconductor fab, especially advanced logic, memory, or foundry environment

• Deep experience with scanner qualification, resist process development, and process of record (POR) establishment at advanced nodes

• Proficiency with lithography metrology tools, overlay metrology, defect inspection, and resist profile characterization

• Strong Design of Experiments skills and statistical analysis capability

• Ability to work closely and proactively across lithography, etch, thin films, integration, and equipment engineering teams

• Tesla is an Equal Opportunity employer. All qualified applicants will receive consideration for employment without regard to any factor, including veteran status and disability status, protected by applicable federal, state or local laws.

• Tesla is also committed to working with and providing reasonable accommodations to individuals with disabilities. Please let your recruiter know if you need an accommodation at any point during the interview process.
