Mechatronics Engineer

Huntington Beach, California, United States

Founded in 2023, Mach Industries is a rapidly growing defense technology company focused on developing next-generation autonomous defense platforms. At the core of our mission is the commitment to delivering scalable, decentralized defense systems that enhance the strategic capabilities of the United States and its allies. With a workforce of approximately 350 employees, we operate with startup agility and ambition.

Our vision is to redefine the future of warfare through cutting-edge manufacturing, innovation at speed, and unwavering focus on national security. We are dedicated to solving the next generation of warfare with lethal systems that deter kinetic conflict and protect global security.

We seek an Mechatronics Engineer to join our new and non-defense consumer robotics program. The engineer in this role will develop mechanical systems end-to-end, from ideation through deployment, working with your peers to make technical and design decisions in the early stages of the product development. High level responsibilities include (but are not limited to):

• Make early technical and design decisions, from part selection through tradeoffs to ensure we can build and manufacture at scale
• Anticipate challenges in actuation, kinematics, sensor integration and embedded controls in order to help keep the team moving forward
• Contribute to test plans, technical documentation, and engineering reviews
• Validate design and iterate hardware based on performance feedback
• Build proof-of-concept designs, run experiments, and communicate findings

• Foundational understanding of mechatronics, mechanism design, kinematics and dynamics
• Demonstrated hands‑on turning ideas into hardware, bridging theory and practicality
• Experience taking ambiguous, open‑ended problems and creating workable design with minimal oversight
• An intrinsic curiosity about hard problems and the motivation to learn unfamiliar systems
• Ability to lead reviews, influence cross‑functional teams, and convey risks and solutions clearly
• Experience making design decisions around 3D CAD, 2D drawings, material selection, and manufacturability

• 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 tradeoffs to get a complete system working
• 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
