Mechanical Engineer, Fauna
Job Description
We’re looking for a Mechanical Engineer to design and develop mechanical systems for our robotic platform. You’ll own the mechanical design of enclosures, mounting systems, cable routing, sensor integration, and peripheral assemblies like our autonomous charging dock. This is a hands-on, CAD-intensive role. You’ll spend your time designing parts, building assemblies, and iterating quickly through prototype build cycles. You’ll work closely with electrical engineers on component packaging and thermal integration, with industrial designers on form factor and aesthetics, and with the broader platform team to solve mechanical problems that span subsystems. The right person for this role is a strong mechanical designer who moves quickly in CAD, thinks in terms of systems and constraints, and is comfortable owning the physical integration of electronics, sensors, and cables into compact assemblies. You’re equally at home designing a precision alignment feature for a charging interface and routing a cable harness through a tight volume. Key job responsibilities - Own mechanical design of peripheral systems and accessories for the robotic platform, from concept through prototype validation - Design and maintain complex assemblies in Onshape with clean parametric architecture that supports rapid iteration - Solve packaging and integration problems: fitting electronics, sensors, connectors, and cables into compact, serviceable enclosures - Develop cable routing and harness packaging solutions within tight volume and serviceability constraints - Drive rapid prototyping cycles using 3D printing, CNC machining, and other methods to validate designs quickly - Collaborate with electrical engineers on component placement, thermal paths, and mechanical interfaces to PCBAs - Work with industrial designers to resolve form, fit, and manufacturability tradeoffs without compromising design intent - Perform tolerance analysis and manage fit/function across multi-part assemblies - Manage prototyping vendor relationships and support DFM reviews as designs mature toward production - Maintain design documentation and participate in design reviews across the team About the team Fauna Robotics, an Amazon company, is building capable, safe, and genuinely delightful robots for everyday life. Our goal is simple: make robots people actually want to live and interact with in everyday human spaces. We believe that future won’t arrive until building for robotics becomes far more accessible. Today, too much effort is spent reinventing the fundamentals. We’re changing that by developing tightly integrated hardware and software systems that make it faster, safer, and more intuitive to create real-world robotic products. Our work spans the full stack: mechanical design, control systems, dynamic modeling, and intelligent software. The focus is not just functionality, but experience. We’re building robots that feel responsive, expressive, and genuinely useful. At Fauna, you’ll work at the frontier of this space, helping define how robots move, manipulate, and interact with people in natural environments. It’s an opportunity to solve hard problems across hardware and software with a team focused on making robotics accessible and joyful to build. If you care about making robotics real for everyone and building systems that are as delightful as they are capable, we’re interested in hearing from you.
