Benchmark Space Systems delivers proven in-space propulsion, High-Test Peroxide systems, ASCENT monopropellant systems, and electric propulsion systems, with 15+ missions launched and less than 12 months concept to delivery.,.

Job Purpose and Primary Objectives:

Benchmark Space Systems is looking for a Propellant Chemistry Intern to join our team for the summer of 2027.

In this role, you will work closely with engineers and chemists to design, build, and test technologies supporting the next-generation of in-space propulsion products for small satellites and other missions. Interns will gain valuable knowledge in industry best practices, propulsion engineering and propellant chemistry, use of engineering software, and documenting and presenting engineering results.

This internship is onsite at our Pleasanton, CA location.

About Benchmark:

At Benchmark Space Systems, we’re pioneering the future of in-space mobility. Our propulsion technologies provide satellites the ability to maneuver, avoid collisions, and maximize mission potential-all while contributing to a safer, more sustainable space environment.

Backed by recent funding and a growing slate of new flight contracts for government and commercial customers, we’re building a workplace where bold ideas and passionate people thrive. Engineers, innovators, and problem-solvers at Benchmark tackle some of the toughest challenges in spaceflight, working together to turn cutting-edge concepts into real-world solutions. If you're ready to help shape the next era of spaceflight, there's never been a better time to join Benchmark Space Systems.
