Mechanical Engineer I

Longshot Space Technologies is at the cutting edge of low-cost space access and hypersonics. We are developing a novel space launch system that accelerates mass over a long distance. Using our technology, we plan to provide affordable launch services for satellites, cargo, and future space infrastructure. Our mission is to enable a future where humans can reach for the stars.

About the role

We're seeking a motivated Mechanical Engineer to join our core engineering team, supporting the design, development, and testing of hardware critical to our kinetic launch technology. You'll work across high-pressure gas systems, thermal protection systems, and structures, building and refining the hardware that powers our launch and vehicle platforms. This is a hands-on role with real growth potential on both technical and leadership tracks. You'll work closely with senior engineers and cross-functional teams spanning mechanical, electrical, fluids, and aerospace engineering, gaining exposure across the full system rather than a single narrow slice.

Responsibilities

• Assist in the design, testing, and integration of all systems for the accelerator and vehicle.
• Contribute to design, manufacture, and test for key subsystems.
• Participate in the assembly, testing, and troubleshooting hardware in lab and field environments.
• Support development and debugging of embedded firmware within our data acquisition systems.
• Create and maintain technical documentation for electronic and firmware systems.
• Collaborate with senior engineers to ensure electrical systems meet performance and reliability goals.
• Support integration of electrical systems with mechanical, fluids, and software components.

Requirements

• Bachelor’s degree in Mechanical, Aerospace, or Systems Engineering preferred.
• 0-2 years experience in a hands-on test, design, manufacturing or R&D setting.
• Experience with high-pressure gas/fluid systems in excess of 500 psi in large volumes.
• Exposure to hydrogen safety, rocket test, or propulsion lab environments a bonus.
• Strong organizational and executional skills, including documentation and planning.
• Passion for learning, problem solving, and working as part of a fast-moving team.
