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 Senior Manufacturing Engineer, Environmental Control and Life Support Systems, reporting to the Senior Manager, ECLSS Manufacturing, to support the development, production, and integration of the systems required for artificial-gravity human-rated space stations.

This will be a full-time, exempt position located in our Long Beach location.

Responsibilities:

Own the manufacturing development, production readiness, and build execution of environmental control and life support system hardware for our artificial-gravity space station
Develop, mature, and optimize manufacturing processes for ECLSS components and assemblies, from prototype builds through production and flight hardware
Partner closely with design engineering to ensure hardware is manufacturable, reliable, inspectable, and scalable from early design trades through final production
Create and maintain manufacturing plans, work instructions, assembly procedures, inspection plans, and production documentation
Drive hands-on fabrication, assembly, integration, and test activities in a fast-paced hardware development environment
Identify and resolve production issues through root cause analysis, failure investigation, corrective actions, and continuous improvement
Lead design-for-manufacturing and design-for-assembly reviews internally and with suppliers
Own manufacturing schedules, build sequencing, and production execution for assigned ECLSS hardware from early development through launch vehicle integration
Work with technicians, quality, supply chain, design engineering, test engineering, avionics, software, and mission operations teams to ensure successful system integration
Support supplier development and manufacturing readiness for externally produced components and assemblies
Evaluate and implement manufacturing techniques for metallic, fluid, thermal, and soft-goods hardware, including machining, welding, brazing, tube bending, cleaning, bonding, and assembly
Bring technical rigor, ownership, and continuous improvement to all aspects of manufacturing engineering

Basic Qualifications

Bachelor’s degree in an engineering or science discipline

Experience developing manufacturing processes, work instructions, build plans, or production documentation for complex hardware

Preferred Qualifications

Master’s degree in an engineering discipline.
Experience supporting production or build execution for aerospace, spacecraft, propulsion, ECLSS, thermal, fluid, or other high-reliability hardware
Strong experience with design for manufacturing and assembly, production readiness, process development, and manufacturing risk reduction
Proactive problem-solving skills, including failure analysis, root cause investigation, corrective action implementation, and design of experiments
Ability to perform trade studies using first principles and engineering fundamentals to make clear recommendations with partial information
Experience with rotating machinery, pumps, valves, heat exchangers, pressure vessels, fans, separators, or other fluid system components
Experience with soft goods, flexible ducting, seals, insulation, or other non-metallic flight hardware
Experience with NX
Solid understanding and application of geometric dimensioning and tolerancing, tolerance stack-up analysis, and inspection planning
Experience with structural analysis methods, including hand calculations, FEMAP, or ANSYS, to evaluate manufacturability, strength, life, and fracture considerations
Knowledge of metallic and fluid system manufacturing techniques, processes, equipment, and special processes, including machining, welding, brazing, tube bending, cleaning, passivation, leak testing, proof testing, and pressure testing
Experience working directly with technicians on the shop floor to troubleshoot builds, improve processes, and execute hardware efficiently
Ability to work well in an integrated, collaborative team environment, including frequent interaction with technicians, engineers, quality, supply chain, and managers
Highly self-motivated with strong organizational and written/oral communication skills; able to prioritize and execute tasks in a high-pressure environment with an ongoing drive for continuous improvement
