Role summary

Salient Motion is seeking an Engineering Co-op to join their team for a minimum 6-month, full-time, paid rotation in Hawthorne, CA. This hands-on role treats co-ops as contributing engineers, allowing them to own real work from design through production release on aerospace, defense, and industrial systems. Responsibilities include designing, building, and testing electro-mechanical systems, firmware, test fixtures, and supporting manufacturing. Candidates should be enrolled in a relevant engineering program, comfortable in a lab/shop environment, and possess strong communication skills. Prior hands-on experience is a plus. Relocation support is available.

**Applicants must be U.S. Citizens or U.S. Permanent Residents (Green Card holders) to meet customer and regulatory requirements**About UsSalient 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 OverviewAs 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 specification 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

    • Co-op Details

  • Full-time, paid co-op, with pay tiered by commitment length:
  • 6-month rotation: $28 to $34/hr
  • 9 to 12 month rotation: $34 to $40/hr
  • Minimum 6-month commitment; 9 to 12 month rotations preferred
  • Start dates flexible to align with your school's co-op calendar. Common cadences include January to June, July to December, and July to June for full-year rotations
  • Onsite in Hawthorne, CA; relocation support includes a $1,200/month housing stipend for students relocating more than 50 miles
