Mechanical Engineer - Precision Systems

About this role

Atomic Semi seeks a hands-on mechanical engineer to design and build precision motion systems and equipment for semiconductor fabrication, working on sub-micron to nanometer-scale machines. You'll prototype and iterate rapidly while collaborating across electrical, controls, and optics teams in an early-stage startup environment.

What you'll do

• Design precision machines, motion stages, and structural systems targeting nanometer-level performance
• Lead mechanical system integration and alignment procedures with cross-functional teams
• Drive mechanical design with GD&T, tolerance analysis, and manufacturability focus
• Rapidly prototype, build, and characterize designs using various fabrication tools
• Select and integrate precision components like bearings, encoders, and actuators
• Develop error budgets and tolerance stack-ups to identify and mitigate error sources

What they're looking for

• Precision machine design and exact-constraint design
• Tolerance analysis and geometric dimensioning and tolerancing (GD&T)
• Hands-on prototyping, fabrication, and assembly
• Dimensional metrology (interferometry, LVDTs, CMMs)
• Precision component selection and integration
• Error budgeting and structural analysis
• CAD and design iteration
• Kinematic couplings and flexure design

Benefits

• Competitive salary range: $115,000–$180,000 annually
• Generous equity package
• Work on cutting-edge semiconductor technology
• Offices in Austin, TX and San Francisco, CA
• Solid funding and world-class advisors
• Access to advanced lab equipment (3D printers, microscopes, e-beam writers)
