About FLX Solutions

FLX Solutions, Inc. builds robotic systems that make inspection and maintenance faster, safer, and more repeatable, especially in tight, hard-to-reach spaces. Our flagship platform, the FLX BOT, is a modular, handheld, snake-like articulating robotic system designed to solve one of the toughest challenges in maintenance: reaching the "last meter" in complex environments. It is already in use with the U.S. Navy, U.S. Air Force, a major DoD prime, and shipbuilders, with expanding applications across industrial, transit, and construction sectors.

We're at the build-and-scale stage. The FLX BOT has moved from prototypes to paying customers in defense, maritime, and industrial markets, and we're growing the team to keep up. If you want your work in the hands of real users within months, not years, and the room to shape how we build, this is the place. 

​

The Opportunity​

The Mechanical Design & Prototyping Engineer role sits at the intersection of technician and engineer, with a clear path to grow into a full design engineering role. You'll be hands-on in the lab every day, building and testing hardware alongside our Assembly team, keeping the 3D printers running, and managing parts inventory, while also doing real engineering work: designing jigs and fixtures in CAD, applying GD&T best practices, and generating the drawings that keep our builds accurate and repeatable.

 

This is a ground-floor seat on the FLX BOT platform as it moves from pilot programs into full-scale production. You'll work closely with the Electrical and Assembly teams and the Senior Mechanical Design Engineer, You'll start with the hands-on build, test, and lab work and take on more of the design as you build your track record, with a clear path toward a senior design role.
