Mechanical Design Engineer

We’re looking for a Senior Mechanical Engineer to take complete end-to-end ownership of our flagship product’s core subsystem: the End Effector . This is a true generalist role for a hands-on engineer who thrives in high-autonomy, fast-paced startup environments. You will drive designs from first-principles hand calculations and FEA analysis, build and machine your own prototypes in-house, and integrate complex electromechanical systems alongside world-class software and electrical teams. What You’ll Do Subsystem Ownership: Own the End Effector end-to-end—from initial CAD and trade studies to shop fabrication, assembly, and field validation. Electromechanical Integration: Package sensors, load cells, precision linear motion components (ball screws, linear stages, bearings), and actuation modules within tight spatial tolerances. Analytical Validation: Validate all designs upfront using hand calculations, FEA, and tolerance stack-up analysis before entering production. Rapid Fabrication: Work hands-on in our in-house machine shop using steel and aluminum fabrication to compress hardware iteration cycles from months to days. Cross-Functional Ownership: Collaborate directly with electrical, software, and controls teams to define sensing and control requirements. What We’re Looking For Location: Available to work 100% on-site 5 days/week in San Francisco, CA. Experience: 5+ years of mechanical engineering experience (including 1–4+ years specifically designing precision electromechanical systems in robotics, aerospace, or automotive). Robotics Track Record: Proven background designing and deploying complex robotic subsystems (actuation, motion, or perception integration). Analytical Discipline: Demonstrated fluency in FEA and first-principles hand calculations to validate physical models prior to manufacturing. Precision Motion Expertise: Deep experience with linear stages, ball screws, bearings, load cells, and multi-component tolerance stack-up analysis. Education: B.S. in Mechanical Engineering (or equivalent practical experience). Bonus Points Hands-on proficiency with steel/aluminum CNC machining and shop tool usage. Prior experience in early-stage startups or lean engineering teams. #J-18808-Ljbffr Brahma Consulting Group
