Engineering Co-op

Engineering Co-op
About Us
Salient Motion is building a modular motion and actuation platform that is redefining how aerospace, defense, and industrial systems are designed, built, and deployed. We move fast, operate with high ownership, and expect real contribution from every member of the team. Co-ops are treated like engineers, not observers. You will own real work, ship to production hardware, and leave with a body of work you can point to.
Role Overview
As an Engineering Co-op, you will embed with our engineering team across mechanical, electrical, software, manufacturing, and systems-level work for six months or longer. Unlike a short summer internship, this role is designed for students who want to take a project from spec through qualification, see a full product cycle, and operate as a contributing member of the team.
This is a hands-on role in a fast-paced startup environment. You will be expected to ramp quickly, take ownership of a defined workstream, and ship work that goes into customer programs.
What You Will Do
Own a scoped engineering workstream from design through test and release, with support from a senior engineer
Design, build, and test electro-mechanical systems and subassemblies on active customer programs
Build, maintain and improve test fixtures, data collection infrastructures
Firmware bring-up, design validation tests for electronics boards
Lead prototyping, assembly, and hands-on lab and shop work
Plan and execute engineering tests, collect data, and present results to the team
Drive manufacturing and supplier activities including part preparation, first-article inspection, and validation
Build and improve engineering and documentation processes that outlast your co-op term
Partner with senior engineers and program leaders, and present progress in design and program reviews
What We Are Looking For
Enrolled in a Bachelor's or Master's program in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field, with the ability to commit to a minimum 6-month co-op rotation
Available for a full-time term, whether a full academic semester, summer plus a connecting semester, or two consecutive semesters
Strong curiosity and willingness to work across disciplines
Comfortable in a lab or shop environment with hardware and tools
Clear communicator who can document work, present results, and ask thoughtful questions
Prior hands-on experience through projects, labs, clubs, personal builds, or a previous internship or co-op is a strong plus
What You Will Gain
Ownership of real production-bound hardware over a long enough window to see it ship
Exposure to aerospace and defense engineering standards and practices through a full program cycle
Mentorship from experienced engineers and direct access to founders and program leadership
A portfolio of shipped work and a reference from a startup that moved on your contributions
Co-ops completing 9+ months in good standing are evaluated for a full-time return offer at graduation
