About the company Our client is a robotics company. The role Raydar is recruiting for this role on behalf of our client. Take ownership of mechanical subsystems for autonomous machines, carrying each from early concept to a functioning prototype. The job mixes design work at the computer with hands-on building and testing in a workshop. You will partner with colleagues across electrical, software and robotics disciplines to bring complete systems together. What you'll do - Lead the design of mechanical subsystems from the first sketches through repeated prototype cycles, selecting materials, tolerances and production methods. - Create part and assembly models in CAD, supported by manual calculations and finite element analysis, with an eye to quick turnaround prototyping. - Fabricate your own test hardware in the workshop with additive and subtractive machines and hand tools. - Fit mechanical designs together with drive components, sensing, controls hardware and moving parts. - Work alongside electrical, software and robotics engineers to combine everything into complete systems ready for field use. What we're looking for - 2 to 5 years of experience in mechanical design. - A record of taking working machines from concept through to functioning hardware, such as mechanisms, joints, drivetrains or grippers. - Experience delivering hardware products within a startup or a small, hands-on team. - BS in Mechanical Engineering or a related field. - Proficiency with a mainstream CAD package such as SolidWorks or Fusion 360. - Practical fabrication skills across 3D printing, CNC work and general workshop equipment. - A strong ownership mindset: you drive subsystems from start to finish without needing direction. - Authorization to work in the US. Bonus points - Background in mechatronic systems that combine motors, sensors or actuators. - Familiarity with FEA or topology optimization. Compensation and benefits - Base salary: USD 150,000 to 250,000 per year - Equity - Health insurance - Retirement plan - Relocation assistance Location and work model - San Francisco, CA, United States - On-site, 5 days per week in office - Full-time
