Mechanical Engineer - Precision Systems

About Atomic SemiAtomic Semi is building a small, fast semiconductor fab.It’s already possible to build this with today’s technology and a few simplifications. We’ll build the tools ourselves so we can quickly iterate and improve.We’re building a small team of exceptional, hands-on engineers to make this happen. Mechanical, electrical, hardware, computer, and process. We’ll own the stack from atoms to architecture. Our team is optimistic about the future and we want to continue pushing the limits of technology.Smaller is better. Faster is better. Building it ourselves is better.We believe our team and lab can build anything. We’ve set up 3D printers, a wide array of microscopes, e-beam writers, general fabrication equipment - and whatever is missing, we’ll just invent along the way.Atomic was founded by Sam Zeloof and Jim Keller. Sam is best known for making chips in his garage, and Jim has been a leader in the semiconductor industry for the past 40 years.About The TeamThe Positioning Team operates on the nanometer scale. We make lithography, metrology and motion systems that pattern, inspect and characterize our chips in order to push our process to lower nodes.About The RoleWe are seeking a highly skilled and hands-on Mechanical Engineer to join our team. You will be responsible for designing, prototyping, and building the mechanical systems in our semiconductor fabrication equipment, from stages and frames up to complete systems.This role is for someone who has internalized precision machine design as a discipline and has a proven track record of rapidly prototyping complex precision systems and advancing them to the next stage of production. Our philosophy is to get things built and tested in days or weeks, not months. Because of this, a portfolio is generally required to apply: show us the things you’ve actually built!ResponsibilitiesDesign and iterate on precision machines, motion stages, structural loops, metrology frames, opto-mechanical mounts, test fixtures, and inspection tooling targeting sub-micron to nanometer performanceLead mechanical system integration, alignment procedures, and cross-team coordination with electrical, controls, and optics engineersDrive mechanical design of frames, stages, and assemblies with GD&T, tolerance analysis, and a practical eye toward manufacturability and assemblyRapidly prototype, build and characterize new designs on the bench using a variety of tools and characterization equipmentSelect and integrate precision components: bearings, encoders, interferometers, actuators, isolators, and dampersDevelop error budgets and tolerance stack-ups; identify and mitigate dominant error sources (thermal, vibrational, structural, kinematic)Required Experience3 years designing and building precision mechanical systems that had to hit real accuracy and repeatability targetsWorking fluency in precision machine design fundamentals: exact-constraint design, kinematic couplings, flexures, error budgeting, structural loops, tolerance analysisHands-on prototyping, fabrication, assembly, and alignment experience — you're comfortable on a mill, on a granite surface plate, and behind an interferometerExperience selecting and integrating precision components (bearings, stages, encoders, isolators, actuators)Experience with dimensional metrology: interferometry, LVDTs, capacitance probes, autocollimators, and CMMsNice-to-haveFormal training in precision engineeringExperience at an early-stage startupFamiliarity with firmware, controls, or electrical engineeringOpto-mechanical design and alignment experienceWorking at Atomic SemiWe’re an early-stage hardware startup with solid funding, world-class advisors, and offices in Austin, TX and San Francisco, CA.Compensation: Atomic Semi is committed to fair and equitable compensation practices. The annual salary range for this role is $115,000 – $180,000. Compensation is determined based on your qualifications and experience. Our total compensation package also includes generous equity in Atomic Semi.Benefits: Atomic Semi offers the following benefits, subject to applicable eligibility requirements:Medical, Dental, and Vision insuranceGenerous Paid Time Off inclusive of Holidays and Sick TimeVisa SponsorshipLife and Disability InsurancePaid Parental Leave401(k) retirement planWeekly Learning & Development opportunitiesCommuter Benefits including Parking and Late Night Uber rides from the officeLunches daily, Dinners 3x per week, Stocked Office Kitchen with Snacks and SpindriftsWe are an equal-opportunity employer and do not discriminate on the basis of race, religion, national origin, gender, sexual orientation, age, veteran status, disability or other legally protected statuses.Export Control Analysis: This position involves access to technology that is subject to U.S. export controls.
