Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich, and low-cost approach. Vast is rapidly developing its multi-module Haven Station 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. 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 in 2027, followed by additional Haven modules. Additionally, the company recently announced Vast Satellite , a high-power satellite product line leveraging its space station components and the heritage of Haven Demo. Headquartered in Long Beach, California , and with more than 1,000 employees and over a billion dollars in private capital, Vast has built...

Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We'd love for you to join us on our mission of providing humankind access to the galaxy beyond our planet. About the Role Apex is seeking a Chemical Propulsion Engineer to join our closely integrated team, driving the...

NX Design Engineer, Gas Turbine Propulsion Orange County, CA • U.S. Persons Only THE OPPORTUNITY The company is developing compact gas turbine engines built to hit demanding performance targets at a fraction of the size and cost of legacy designs. This is a hands-on role for a design engineer who can take a mechanical design from a blank sheet through to a producible part - someone who is genuinely excellent at CAD (NX strongly preferred), with a real track record of designing complex mechanical assemblies, ideally backed by a portfolio or patents that show what they've owned. Direct experience with rotating machinery, turbomachinery, or jet engines is a real plus and helps you ramp quickly, but the core bar is CAD depth and assembly-design ownership in a lean, fast-moving environment where engineers cover more ground than they would at a larger company. No new-grad or intern-level openings at this time. Must be a U.S. person. KEY RESPONSIBILITIES Own engine components...

Amca is building America's new industrial base. Since the 1990s, our ability to build new aviation and military systems and maintain the ones we already have has eroded. Today, the gap between what the nation needs to produce and what it is capable of producing is the largest it has been in generations. To help close that gap, Amca rapidly develops and manufactures new critical components and subsystems required to build and sustain the planes, military vehicles, and core infrastructure America needs. Today, we operate seven factories nationwide, including our advanced prototyping and testing headquarters in El Segundo, and deliver avionics, hydraulic, and electrical components for platforms such as the F-35, F-16, F/A-18, 737MAX, 787, A320neo, A321, Mk-48, and M1 Abrams. Overview The Senior Propulsion Component Engineer owns the design of Amca's propulsion control hardware, taking components and assemblies from concept through qualification. You will lead the design of valves,...
