Spring '27 Intern - Mechanical Engineering

moss robotics; San Francisco (CA); On-site; USD 28,000 - 55,000; Full time

Job summary

moss.inc is seeking a Mechanical Engineering candidate to drive hardware development for robotic sensor kits. You will own projects across structural design, thermal management, and packaging for rugged deployments in field environments.

You will guide the full hardware development cycle from concept CAD through rapid prototyping, testing, and supplier coordination, collaborating closely with perception, robotics, and electrical teams. Interns and full-time engineers are welcome to apply.

Qualifications

• Hands-on hardware experience demonstrated outside classwork.
• Understanding of structural analysis and failure modes in mechanical systems.
• Proficiency with CAD and FEA modeling tools.
• Solid understanding of GD&T principles.
• Ability to make engineering trade-offs with partial information.
• Experience integrating sensors, compute, and power into hardware.
• Experience building, assembling, and debugging hardware.

Responsibilities

• Conceptualize new mechanical architectures for robotic systems in harsh environments.
• Lead design reviews with suppliers and partners.
• Develop enclosure systems for thermal management, vibration resistance, and weather protection.
• Perform tolerance analysis and DFM reviews with manufacturing teams.
• Own prototype builds and field-test validation.
• Collaborate with perception, robotics, and electrical teams for full-system integration.

Job description

About Us

At moss.inc, we are making the physical world searchable. Our sensor kits mount to vehicles our customers already drive, and turn every drive into a measured 3D record of their site, across agriculture, construction, and energy. Our AI models then parse through those 3D maps and decipher important information for each of our customers. We started with tree farms, where a single field holds millions of plants no human has ever fully inventoried.

We're a small team of practical engineers with a long-term vision. We focus on real, messy, on-the-ground problems today, while working toward a future where AI agents understand the physical world.

If our mission aligns with how you work and think, we'd love to learn more about you.

The Role

Join us as a Mechanical Engineering Intern on a fast-moving team of seven. Here, you’ll build things that actually get deployed. You’ll own projects across structural design, thermal performance, and packaging for our next-generation robotic sensor kits.

Be ready to work through the full hardware development cycle: concept CAD, rapid prototyping, FEA, DFM iteration, supplier coordination, assembly, and field validation in live farm environment.

We're looking for both a full time engineer, and intern candidates for co-ops, summer, and/or part-time roles.

Minimum Requirements

• Track record of hands-on personal projects (outside the classroom) demonstrating hardware skills
• Demonstrated understanding of structural analysis and failure modes of complex mechanical systems
• Proficiency in CAD software and FEA modeling
• Solid understanding of GD&T
• Comfortable making first-principles engineering trade-offs, even with partial information
• Experience integrating sensors, compute, and/or power systems into physical assemblies
• Comfortable building, assembling, and debugging physical hardware

What You'll Do

• Conceptualize new mechanical architectures for robotic systems in harsh environments
• Lead design reviews internally and externally with suppliers and partners
• Develop enclosure systems for thermal management, vibration resistance, and weather protection
• Perform tolerance analysis and DFM reviews with manufacturing partners
• Own prototype builds and field-test validation
• Collaborate closely with perception, robotics, and electrical teams to optimize full-system integration
