Key Responsibilities: 

• 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 

 

Required Skills and Experience 

• 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 / ISO9001 quality systems, including NCR, CAPA, FAI, and compliance enforcement 
• Experience with root cause analysis, problem solving, and continuous improvement methodologies 
• Hands-on experience supporting production floor activities in cleanroom or controlled environments 
• Strong communication and collaboration skills across cross-functional engineering and operations teams 

 

Desired Skills and Experience: 

• MS in Mechanical, Aerospace, Manufacturing Engineering or related field 
• Experience in spacecraft or high-reliability aerospace environments (NASA, DoD, commercial space) 
• Experience supporting or leading Environmental campaigns (TVAC, Vibration) and integration with Test Engineering teams 
• Familiarity with non-destructive testing (NDT) methods and interpretation of inspection results 
• Ability to contribute to systems-level trades, requirements flow-down, and vehicle architecture decisions impacting manufacturability 
• Experience scaling hardware from prototype through production (rate manufacturing), including line balancing and cycle time optimization 
• Experience with PLM/MES systems, digital manufacturing, and configuration management workflows 
• Demonstrated ability to operate across disciplines, stepping into Test, Quality, Integration, or Operations roles as needed 
• Experience interfacing with customers and supporting technical/program reviews (PDR, CDR, TRR, LRR) 
• Leadership experience mentoring engineers and technicians in a high-growth or startup environment 
• Strong adaptability and ownership mindset with the ability to solve ambiguous problems with minimal guidance  

Education & Work Experience: 

1. BS in Mechanical, Aerospace, Manufacturing Engineering or related field (MS preferred) 
2. 5+ years of relevant experience in aerospace or space systems manufacturing 

Compensation: 

Annual Base Salary Range: $130,000.00 - $165,000.00/per year 
Base pay is one part of our total compensation package (base+bonus+equity) and is determined within a range. Your actual base salary will be determined on job-related knowledge and skills, education, and experience.
