Mechanical Engineer - Precision Systems

Atomic Semi • Austin, TX

1d • $115,000 - $180,000 • Onsite

About The Position

Atomic Semi is building a small, fast semiconductor fab using today's technology with simplifications, building their own tools for rapid iteration. They are assembling a small team of exceptional, hands-on engineers across various disciplines to own the entire stack from atoms to architecture. The Positioning Team specifically focuses on nanometer-scale systems, creating lithography, metrology, and motion systems for chip patterning, inspection, and characterization to advance process nodes. The role requires a highly skilled and hands-on Mechanical Engineer to design, prototype, and build mechanical systems for semiconductor fabrication equipment, including stages, frames, and complete systems. The ideal candidate has a deep understanding of precision machine design, a proven ability to rapidly prototype complex precision systems, and a philosophy of building and testing in days or weeks, not months. A portfolio showcasing built projects is generally required.

Requirements

• 3 years designing and building precision mechanical systems that had to hit real accuracy and repeatability targets
• Working fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysis
• Hands-on prototyping, fabrication, assembly, and alignment experience — you're comfortable on a mill, on a granite surface plate, and behind an interferometer
• Experience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators)
• Experience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMs

Nice To Haves

• Formal training in precision engineering
• Experience at an early-stage startup
• Familiarity with firmware, controls, or electrical engineering
• Opto-mechanical design and alignment experience

Responsibilities

• Design and iterate on precision machines, motion stages, structural loops, metrology frames, opto-mechanical mounts, test fixtures, and inspection tooling targeting sub-micron to nanometer performance
• Lead mechanical system integration, alignment procedures, and cross-team coordination with electrical, controls, and optics engineers
• Drive mechanical design of frames, stages, and assemblies with GD&T, tolerance analysis, and a practical eye toward manufacturability and assembly
• Rapidly prototype, build and characterize new designs on the bench using a variety of tools and characterization equipment
• Select and integrate precision components: bearings, encoders, interferometers, actuators, isolators, and dampers
• Develop error budgets and tolerance stack-ups; identify and mitigate dominant error sources (thermal, vibrational, structural, kinematic)

Benefits

• Medical, Dental, and Vision insurance
• Generous Paid Time Off inclusive of Holidays and Sick Time
• Visa Sponsorship
• Life and Disability Insurance
• Paid Parental Leave
• 401(k) retirement plan
• Weekly Learning & Development opportunities
• Commuter Benefits including Parking and Late Night Uber rides from the office
• Lunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and Spindrifts
