At Vast, our mission is to contribute to a future where billions of people are living and thriving in space. Vast is developing next-generation space stations to ensure a continuous human presence in space for America and its allies, enabling advanced microgravity research and manufacturing, and unlocking a new space economy for government, corporate, and private customers. Using an incremental, hardware-rich and low-cost approach, Vast is rapidly developing its multi-module Haven Station. Haven Demo’s 2025 success made Vast the only operational commercial space station company to fly and operate its own spacecraft. Next, Haven-1 is expected to become the world’s first commercial space station when it launches, followed by additional Haven modules to enable permanent human presence by 2030. Our team is all-in, committed to executing our mission safely and on time. If you want to work with the most talented people on Earth furthering space exploration for humanity, come join us.
Vast is looking for a Mechanical Engineer, reporting to the Manager, Structures Design, to to support the development of the systems that will be required for the design and build of artificial-gravity human-rated space stations.
This role blends mechanical and systems engineering with human-factors-driven product development to shape the environments where astronauts will live and work aboard our stations.
This will be a full-time, exempt position located in our Long Beach location.
Responsibilities:
- Own end-to-end design, development, and integration of in-flight equipment—from concept and requirements through analysis, selection, qualification, manufacturing readiness, and flight verification.
- Develop and maintain packaging layouts for all cargo- optimize equipment placement to meet volume, mass, accessibility, and center-of-gravity constraints
- Own requirements, run trade studies, and drive decisions with clear engineering rationale
- Develop qualification and acceptance testing for all in-flight equipment. Design test fixtures, coordinate and execute all testing (off-gassing, flammability, mechanical loads, EMI/EMC, environmental exposure).
- Produce detailed CAD models, engineering drawings, analysis reports, test plans, and concepts of operations; lead hardware through manufacturing/procurement, test, integration, and verification
- Participate in human-in-the-loop evaluations, mockups, packing studies and fit checks
- Work cross functionally with teams (Flight Surgeons, Food Scientists, Thermal, ECLSS, Avionics)
- Ensure hardware, packaging, and stowage solutions meet mission requirements, human factors and safety through cross-functional ownership
Minimum Qualifications:
- Bachelor’s degree in mechanical engineering, aerospace engineering, or a related engineering discipline
- 5+ years of mechanical design and analysis experience, including development of mechanical components, systems, or safety-critical equipment
- 5+ years of experience with CAD and FEA tools
Preferred Skills & Experience:
- Experience developing spaceflight hardware or safety equipment in regulated or high-reliability domains
- Hands-on experience supporting environmental testing (structural, random vibration, thermal, EMI/EMC)
- Experience with aerospace, medical, or high-reliability packaging systems
- Experience with flexible packaging, barrier materials, or food-grade polymers
- Ability to lead trade studies using first-principles reasoning, even with limited data.
- Leadership experience on an engineering or project team
- Strong ability to use data and analysis to make fast data-driven decisions
- Demonstrated ownership of hardware from concept through design, build, integration, and verification.
- Excellent communication skills; ability to synthesize inputs across teams (avionics, materials, human factors, structural, safety, procurement).
- Comfort working in ambiguity; ability to move fast, take ownership, and deliver under tight schedule constraints.
- Highly organized individual with excellent documentation practices, attention to detail, and the ability to track information accurately across projects
Pay Ranges:
- Mechanical Engineer II : $110,000 - $142,000
- Senior Mechanical Engineer: $135,000 - $176,000
