Mechanical Engineer I - Spacecraft Programs

Job DescriptionQuantum Space is redefining mobility and autonomy beyond Earth orbit. Our Ranger spacecraft deliver high delta-V and sustained on-orbit maneuverability, enabling missions across cislunar and geostationary space that were previously out of reach. We are building the vehicles, infrastructure, and operational expertise that connect and protect assets across the Earth–Moon system.Who We’re Looking ForQuantum Space is seeking a Mechanical Engineer I to support the development of flight hardware for our Spacecraft Programs. This role is designed for an early-career engineer who wants to build strong fundamentals by contributing to real hardware from concept through integration and test.You will work closely with experienced engineers, AIT, and manufacturing teams to execute well-defined scopes while learning how flight hardware is actually built, not just designed.Where You’ll Make an ImpactSupport design of mechanical components and simple subsystems under guidanceCreate CAD models and detailed drawings in Creo, applying GD&T with mentorshipAssist in interface definition: envelopes, mounting schemes, and basic alignment featuresSupport hardware builds and integration activities, including hands-on work when neededAssist with issue triage and root-cause investigations during integration and testContribute to verification efforts: fit checks, basic functional checks, and test documentationPrepare clear documentation for design reviews and configuration trackingSupport supplier coordination through drawing clarifications and basic review feedbackWhat It TakesBS in Mechanical Engineering or related field0–2 years of relevant experience (internships or project teams acceptable)Exposure to CAD (Creo preferred, but not required)Basic understanding of engineering drawings and GD&T principlesStrong fundamentals in mechanics, materials, and designWillingness to work hands-on with hardware in a lab/integration environmentWork location within the DMV areaNice-to-Have ExperienceInternship or academic project involving hardware build/testExposure to aerospace or space systemsFamiliarity with basic analysis tools (FEA, MATLAB, or Python)Experience with machine shop tools or prototypingWhat You’ll GetOwnership – Real contribution to flight hardware early in your careerMentorship – Direct learning from experienced spacecraft engineersGrowth – Clear path to subsystem ownershipCompensation – Competitive salary, equity, and comprehensive benefitsLocation: Rockville, MDCompensation: $75,000 to $125,000 Annual Salary Depending on ExperienceAdditional RequirementsTo comply with U.S. Government space technology export regulations, including ITAR, applicants must be a U.S. citizen, lawful permanent resident, protected individual per 8 U.S.C. 1324b(a)(3), or eligible to obtain required authorizations.
