Fall '26 Intern - Mechanical Engineering
Moss
About Us At moss.ag, we build robots to go where humans won't, digitizing the physical outdoor world to make it machine-readable. Starting 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 autonomous field robots make harsh outdoor jobs easier and safer. 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 #J-18808-Ljbffr Moss
