Salary: $23-$30hr

Role Summary:

Specter Aerospace is seeking aPropulsion Engineer Co-op(4-6+ month cycle) to be a significant contributor to the development and testing of hypersonic propulsion systems. Those in this role will have the opportunity to take ownership in the design, manufacturing, and test of advanced ramjet/scramjet engine hardware. A successful candidate will have a passion for both hands-on work and the analysis ofthermofluidsystems.

Note: Specter hires both Propulsion DesignEngineerCo-ops and Propulsion TestEngineerCo-ops from this application, depending on an applicants interestand experience. Pleasesubmitan application to this posting if you are interested in either position.

About Specter Aerospace:

Specter Aerospace is building the next generation of hypersonic vehicles for U.S. Forces and Allies. Specter is headquartered just north of Boston in Peabody, MA where itleveragesits advanced propulsion technologies, manufacturing, and testing capabilities to rapidly develop supersonic and hypersonic systems. Funded by a mix of government R&D organizations and private funding, Specter is expanding its team in preparation for flight testing and full-scale production.

Specter offers a wide diversity of tasks, projects, and technical exposure, all while providing co-ops with the same resources and project ownership as our full-time staff members.
