With an experienced team of aerospace, propulsion, and robotics engineers, Momentus has developed a cost-effective and energy-efficient in-space transport system.

Daring problems require daring solutions. We boldly charge into uncharted territory knowing that no matter the outcome we will benefit from the journey and move closer to our goals no matter what. Our teams know that working at Momentus means more than building innovative technology, it means creating entirely new markets in the space economy. We are level-headed, business-minded strategic thinkers intent on providing immediate value to our customers today while simultaneously preparing for the vast possibilities of the future.

If this sounds like you, we should talk.

We are seeking a Spacecraft Vehicle Manufacturing Engineer to support spacecraft Assembly, Integration, and Test (AI&T) for Momentus satellite bus programs with hosted payloads supporting commercial, scientific, and government missions.

This role is responsible for developing and sustaining end-to-end spacecraft manufacturing processes, including build sequences, tooling strategies, MGSE, and production methodologies. The ideal candidate thrives in a fast-paced environment, operates with a high degree of ownership, and bridges design, manufacturing, test, and quality to ensure scalable, compliant, and efficient spacecraft production.

• Develop, own, and maintain spacecraft-level manufacturing plans, including AI&T build sequences, work instructions, travelers, and standard work
• Define and implement production methodologies, tooling strategies, and MGSE, including fixture/tool design, validation, and lifecycle management
• Design assembly fixtures, mechanisms, and production support equipment using CAD; generate drawings and manage fabrication through vendors
• Propose and optimize sequence of operations, integration flow, and installation processes to maximize efficiency and minimize risk
• Perform DFM/DFA analysis, tolerance stack-ups, and manufacturability assessments to ensure design compatibility with production constraints
• Apply GD&T principles, tolerance analysis, and advanced metrology techniques to ensure compliance to engineering specifications
• Support and/or oversee non-destructive testing (NDT) activities (ultrasonic, radiographic/X‑ray, etc.) and ensure proper interpretation of results
• Lead Manufacturing Readiness Reviews (MRR) and ensure production system readiness for spacecraft builds
• Investigate and resolve technical, operational, and quality issues using structured root cause analysis and CAPA methodologies
• Interface with Production, Design Engineering, Test, Quality, EH&S, and Supply Chain to ensure safe, compliant, and efficient execution
• Support Test Operations by ensuring hardware readiness, configuration control, and manufacturability alignment
• Ensure configuration control, traceability, and documentation integrity across all manufacturing processes and hardware
• Mentor engineers and technicians and drive best practices for scalable spacecraft production
• Participate in Integrated Product Teams (IPTs) and technical reviews (PDR, CDR, TRR, LRR) to ensure alignment between design and manufacturing

• 10–15 years of experience in aerospace or space manufacturing, spacecraft AI&T, or complex electromechanical system integration
• Strong expertise in manufacturing process development, including work instructions, routing, build sequencing, and production flow optimization
• Proven experience with tooling and fixture design, including CAD modeling, drawing release, and vendor fabrication support
• Deep knowledge of GD&T, tolerance analysis, and precision measurement techniques
• Experience interpreting and working with engineering drawings, specifications, and inspection/test data
• Strong understanding of AS9100 / ISO
  9001 quality systems, including NCR, CAPA, FAI, and compliance enforcement
• Experience with root cause analysis, problem solving, and continuous improvement…
