Job description
Mechanical Engineer
Substrate is addressing one of the most important technological problems facing the United States. At the intersection of advanced manufacturing and cutting‑edge physics, we are developing technologies that will reshape the semiconductor industry and strengthen America's technological leadership. We are a team of world‑class scientists, engineers, and technical experts building technology for the United States.
Summary
As a Mechanical Engineer, you will design and develop ultra‑high vacuum (UHV) systems, precision mechanisms and high‑speed motion systems. This role requires deep hands‑on engineering experience in high‑precision manufacturing environments combined with the ability to work autonomously on complex technical challenges. You must be comfortable supporting scientists, engineers, and technical specialists working on parallel projects across multiple locations including external production sites. This is a full‑time, in‑office position.
Responsibilities
Design and analyze UHV-compatible mechanical systems, components, and assemblies for state‑of-the-art production facilities across distributed operational environments
Develop nanometer‑precision mechatronic systems for high‑speed, high‑acceleration applications
Conduct structural analysis, vibration and thermal modeling, and FEA stress/strain calculations for high‑acceleration mechatronic systems deployed in multiple locations
Design vacuum‑compatible mechanical assemblies and wafer handling robotics supporting autonomous production workstreams
Build and execute comprehensive testing protocols including UHV validation, precision measurement, and performance characterization for field deployments
Collaborate with electrical engineers and software teams on integrated mechatronic system design across parallel technical contributions
Implement vibration damping techniques and precision isolation systems for distributed production environments
Lead technical troubleshooting and root cause analysis for mechanical failures in systems across multiple installation sites
Develop manufacturing processes and work directly with specialized vendors for precision components and vacuum‑compatible materials
Support external site installations and provide technical guidance for UHV production facility deployments
Drive continuous improvement initiatives for precision mechanical systems across fluid organizational structures
Required Qualifications
6+ years hands‑on mechanical engineering experience, 3+ years in precision manufacturing or research environments at technology companies
Expert‑level CAD experience with complex precision assembly design and UHV-compatible components
Direct experience with finite element analysis (FEA) for stress/strain calculations in high‑acceleration mechatronic applications
Strong background in vacuum technology, UHV system design, and vacuum‑compatible materials
Cross‑functional collaboration experience supporting autonomous technical contributors
Built precision mechanical systems from concept through production in scaling technology environments
Bachelor's degree in Mechanical Engineering or related technical field
Preferred Qualifications
Basic knowledge or experience with semiconductor wafer handling robotics or equipment
Experience supporting scientists and researchers in autonomous technical environments with fluid organizational structures
Experience with nanometer‑precision actuators, motors, and positioning systems
Hands‑on experience with vibration damping techniques for high‑precision mechanical systems
Background in national labs, semiconductor equipment, or custom vacuum system design companies
Salary Range
$150,000-$400,000 USD
