Mechanical Lead: Field-Ready Sensor Hardware

moss robotics; San Francisco (CA); On-site; USD 140,000 - 190,000; Full time

Job summary

moss.inc is seeking a Mechanical Engineering Lead in a full-time role on a seven-person team. You will own mechanical architecture, drive production of the sensor kit, and guide enclosure systems for thermal, weather, and vibration resilience, collaborating with electrical and perception engineers.

You’ll mentor engineers and interns, coordinate with manufacturers, and travel to customer sites and partners as needed to validate designs and ensure robust field performance.

Qualifications

• Shipped at least one hardware product from concept to production and can explain what broke and how you fixed it
• Proven thermal design projects (cooling electronics inside sealed enclosures, heat sinking and heat paths)
• Proven vibration and shock projects (mounting and isolation, fatigue, modal analysis)
• Designed sealed enclosures for outdoor use (IP rating, gaskets and seals)
• Deep CAD and FEA experience on real products
• Strong understanding of structural analysis and failure modes of complex mechanical systems
• Experience designing for production processes (machining, sheet metal, injection molding)
• Solid understanding of GD&T and tolerance analysis
• Comfortable making first-principles engineering trade-offs
• Experience integrating sensors, compute, and power systems
• Experience working with manufacturers (DFM reviews, contract manufacturers, sourcing, assembly and test)
• Comfortable building, assembling, and debugging physical hardware
• Experience leading other engineers or mentoring interns
• Able to travel to customer sites and manufacturing partners

Responsibilities

• Own mechanical architecture decisions, material selection, and detailed design for every moss product
• Take the current sensor kit through production: sourcing, DFM, assembly, failure analysis, and field repairs
• Design the next revision of the sensor kit and bring it to production
• Develop enclosure systems for thermal management, vibration resistance, and weather protection
• Validate hardware against IP, vibration, thermal, and fatigue failures, and fix what fails
• Perform tolerance analysis and DFM reviews with manufacturing partners
• Own prototype builds and field-test validation with customers
• Work with perception, robotics, and electrical engineers on how the full system fits together
• Own relationships with manufacturing partners and component suppliers, in the US and overseas
• Lead design reviews internally and externally with suppliers and partners
• Mentor interns and future mechanical engineers
