Mechanical Engineer Location: Playa Vista, California (in-person, five days per week) The return lane isn't going to build itself. Come build it with us. Outpost is an orbital logistics company rewriting the rules of global logistics by building reusable Earth-return vehicles that unlock in-space manufacturing, on-orbit warehousing, and 60-minute global delivery through space. Our CarryAll vehicle family returns payloads ranging from 200 kilograms to 10 metric tons, lands within 10 meters of its target, and can then be refurbished and launched again. One vehicle, many missions: responsive logistics and precision delivery for national security; commercial cargo moved with real cadence; R&D payloads flown, tested, and refined across repeatable cycles; and critical aid delivered where roads and runways can't reach. The demand is already here, validated through defense and civil agreements and supported by a growing pipeline of government and commercial customers. We...

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 skilled Mechanisms Engineer, Payloads to join our satellite engineering team. In this...

The Role LettrLabs is reinventing direct mail. With our own in-house handwriting robotics, we're challenging traditional direct mail manufacturing from the ground up. We're looking for a Senior Mechanical Design Engineer to own the mechanical design and development of complex electromechanical systems from concept through production - and to be instrumental in building our next-generation production automation platform. You'll take projects end-to-end: translating requirements into robust, manufacturable designs, validating them through analysis and prototyping, and seeing them through to commissioning. You'll work closely with cross-functional partners in electrical, controls, manufacturing, and quality, as well as external vendors and suppliers. This is a hands-on, high-ownership position for an engineer who is equally comfortable at a whiteboard, in CAD, and on the shop floor. Why Join Us Design the machines that make our product possible - you're not supporting a...

About Us At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We're fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we're building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space. The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy. About the Role As a Level I or Level II Mechanical Design Engineer in the Mission Engineering team, you...
