Mach Industries, founded in 2023, is a rapidly growing defense technology company with ~350 employees developing next-generation autonomous defense platforms. The company operates with startup agility while focusing on scalable, decentralized defense systems for the US and its allies. You will join a small, high-ownership mechatronics and robotics team in San Francisco, operating as a startup within Mach. This role offers end-to-end mechanical systems development from ideation through deployment, with significant technical agency and cross-functional influence. Key Responsibilities: - Anticipate and solve challenges in actuation, kinematics, sensor integration, and embedded controls - Make early technical and design decisions, from part selection through manufacturability tradeoffs - Contribute to test plans, technical documentation, and engineering reviews - Validate designs and iterate hardware based on performance feedback - Build proof-of-concept designs, run experiments, and communicate findings to the team - Lead technical reviews and influence cross-functional teams on design decisions You will work on complex mechanical integration challenges, bridging theory and practical engineering to deliver products that scale from prototype to production. Requirements: - Foundational understanding of mechatronics, mechanism design, kinematics, and dynamics - Demonstrated hands-on experience turning ideas into hardware - Proven ability to tackle ambiguous, open-ended problems and create workable designs with minimal oversight - Intrinsic curiosity about hard problems and motivation to learn unfamiliar systems - Ability to lead reviews, influence cross-functional teams, and clearly communicate risks and solutions - Experience making design decisions around 3D CAD, 2D drawings, material selection, and manufacturability Preferred Qualifications: - BA degree or equivalent practical experience in electrical engineering, mechanical engineering, computer science, robotics, physics, or mathematics - Experience with rapid fabrication, tolerance analysis, and mechanical simulation - Ability to collaborate across disciplines and evaluate system-level tradeoffs - Understanding of high-volume manufacturing processes (injection molding, die casting, stamping, machining, bonding) - Proven record of mechanically integrating electronics (sensors, PCBs, antennas, batteries) in complex assemblies - 3+ years of experience taking hardware products from concept to production with a portfolio of shipped mechanical designs Note: This position may require access to information protected under U.S. export control laws (EAR and ITAR).
