Principal Mechanical Engineer Build the Future of High-Performance Connectivity At ThinKom, we don't just build antennas - we design high-performance, next-generation mechanical systems that connect the world across air, land, sea, and space. From Inflight Connectivity (IFC) to High-Power Microwave (HPM) systems to Defense SATCOM, our technology operates in some of the world's most demanding environments. We're looking for a Principal Mechanical Engineer who loves hands-on engineering, thrives on solving hard hardware problems, and wants to see their designs go from napkin sketch to physical deployment. If you're ready to lead critical programs, mentor rising talent, and push the limits of advanced satellite communications, this is your platform. Position Summary As a Principal Mechanical Engineer, you will lead the mechanical design, analysis, development, and manufacturing of advanced stationary and mobile antenna systems and related mechanical assemblies. You'll work closely...

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly. Who We're Looking For We are seeking a Mechanical Engineer III to lead the design and development of electric propulsion hardware and associated subsystems, from concept through flight. This role is intended for an experienced engineer who can own propulsion-related hardware, drive design decisions, and deliver flight-ready systems. You will operate at the intersection of mechanical design, thermal management, and high-performance hardware development, working closely with propulsion, systems, and test teams. Where You'll Make an Impact Own mechanical design of electric propulsion subsystems (thruster assemblies, structural interfaces, feed systems, thermal management hardware) Lead architecture and packaging trades for...

Quantum Space is redefining mobility and autonomy beyond Earth orbit. Our Ranger spacecraft deliver high delta-V and sustained on-orbit maneuverability, enabling missions across cislunar and geostationary space that were previously out of reach. We are building the vehicles, infrastructure, and operational expertise that connect and protect assets across the Earth-Moon system.

Mechanical Engineer (Structures) - Space Solar Position Details Location: Los Angeles (Hawthorne), CA Employment Type: Full-time Department: Structures Travel: Occasional About Starpath Starpath develops and manufactures the technologies that will enable humans to live on the Moon and Mars. Today, we are building robotic systems that locally produce the essential commodities a lunar civilization will require at extreme scale: water, power, and oxygen. Our ultimate goal is to build and operate a self-sustaining city on Mars. The Role The Structures team designs and builds the mechanical backbone of Starpath's hardware - the primary and secondary structures, mechanisms, and interfaces that must survive the punishing loads of launch and the extreme environments of space and planetary surfaces. From the systems that produce water, power, and oxygen on the Moon to the equipment bound for Mars, every subsystem depends on structures that are light, strong, and manufacturable at...

About Starpath Starpath Robotics is developing a full-stack solution for commercial scale rocket propellant production on the Moon and Mars. We are building one of the key enabling technologies that will make humans a multi-planet species. If high ownership, fast pace, working with hardware, and solving challenging technical problems sound like a dream come true, come join the team! Senior/Principal Mechanical Engineer In this role, you will be responsible for the development of critical mechanical systems on Starpath's Rover platform. Depending on your prior work experience, you may work on a variety of systems, such as: (1) low-cost, high-reliability electromechanical actuators, (2) various structures and passive mechanisms, or (3) thermal control systems and autonomy hardware integration. You will own these systems from developing design requirements through to flight. Responsibilities: Own architectures, systems, subsystems, and components from requirements to...
