Mechanical Engineer

About the role

About fab2 The fab2 team can build anything. We design all the hardware and software needed to make chips and we make the fabs, tools, and components ourselves. We're looking for exceptional, hands-on people who can iterate to the limits of what's possible.   fab2 was founded by Sam Zeloof https://www.youtube.com/@SamZeloof and Jim Keller https://en.wikipedia.org/wiki/Jim_Keller_(engineer). 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 team We're hiring for a range of experience levels across several specialized teams: - The Positioning Team focuses on systems-level engineering, designing, prototyping, and building semiconductor fab equipment and subsystems related to lithography, motion, and metrology. - The Vacuum Team is responsible for designing, prototyping, validating, and scaling core semiconductor fabrication equipment. Tool families include Anneal, Deposition, Etch, and Supporting Infrastructure, with goals for each ranging from fundamental design to automation readiness to manufacturing scale-up. - The Packaging Team is responsible for designing, manufacturing, and overseeing the fabrication processes for semiconductor packaging devices. This position emphasizes designing, iterating on, and building specialized equipment for the manufacturing flow, such as laser ablation machines, reflow ovens, and automated metal plating facilities. - The Automation Team develops robotic automation systems to rapidly produce semiconductor packaging devices. About the role As a Mechanical Engineer at fab2, you'll design, iterate on, and build specialized equipment for semiconductor fabrication. We're looking for hands-on engineers across various disciplines to design, iterate on, and build complex systems. Whether tackling heavy design challenges, integrating mechanical, optical, and electronic components, or automating production and manufacturing processes, our philosophy is to get things built and tested in days or weeks—not months—with a focus on viable solutions that meet real production needs. The ideal candidate moves through design cycles fast and can own the end to end process. Our philosophy is to get things built/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! Responsibilities - Design and iterate on machines and subsystems for semiconductor packaging fabrication - Create mechanical designs including frames, components, and assemblies - Integrate mechanical, electrical, and optical components in system assembly, including wiring, optics alignment, and electronics - Collaborate with cross-functional teams to continuously improve fabrication processes and equipment - Source components and materials while working with vendors to meet project specifications Required Experience - 2-7 years of professional experience in mechanical and electromechanical system design - 2-7 years of hands-on experience building, prototyping, and assembling complex systems - Degree in Mechanical Engineering, Electrical Engineering, Mechatronics, Automation, or Physics Nice-to-have - Master's degree and 3+ years of relevant experience - Home workshop/lab experience demonstrating passion for hands-on engineering - Experience building laser machines with comprehensive knowledge of laser system components - Experience working in both R&D and production environments with hardware - System integration expertise across mechanical, electrical, and software domains - Experience with opto-mechanical system design - Circuit design capabilities for custom control systems and instrumentation - Basic coding skills for equipment control Working at fab2 We’re an early-stage hardware startup with solid funding, world-class advisors, and labs/offices in Austin, TX, Lockhart, TX, and San Francisco, CA.
