K2 Space is building large, high-powered spacecraft for the next generation of space development. Backed by Lightspeed Venture Partners, Altimeter Capital, and many others ($200M raised to date), we intend to mass produce the highest-powered satellite platforms ever built for missions across LEO to Deep Space. The rise of launch vehicles like Falcon 9 and Starship enables the move from an era of mass constraint to one of mass abundance.

We believe this new era requires spacecraft with a fundamentally different design in order to fully utilize the massive rockets coming to market. We’re a team that believes the future lies in building large, high-powered satellites that can handle multiple orbits. This is a necessity if we ever want to develop the solar system, and become a Kardashev Type II (K2) civilization.

If you are a motivated individual who thrives in a fast-paced environment and you’re excited about contributing to the success of a groundbreaking Series B space startup, we’d love for you to apply.

You will own the successful implementation of Hall thruster development and production tests for both R&D and production. In your first 6 months, you will develop diagnostics and testing instrumentation for propulsion systems, vacuum systems, and test equipment. In your first year, you will validate flight hardware using your proven diagnostic tools, participate in multidisciplinary test campaigns, and play a critical role in qualifying the highest-powered Hall thruster system ever to fly in space.

In your first two years, you will take on larger propulsion test campaigns and ownership while directly supporting production and qualification testing.

• Setup, commission, and maintain state-of-the-art vacuum chambers, test stands, and data acquisition systems for Hall thruster propulsion systems
• Perform tests on a novel 20 kW Hall thruster, feed systems, power electronics, and hardware-in-the-loop electrical systems
• Develop testing and control scripts to conduct safe and reliable test campaigns of Hall thruster propulsion systems and components
• Create formal documentation for development and production: test procedures, test reports, standard operating procedures
• Troubleshoot electrical and mechanical test setups and hardware
• Document, compile, analyze, and present test data

• Bachelor’s degree in mechanical, aerospace, electrical, or other relevant engineering discipline
• +2 years of hands‑on electric propulsion system test experience
• Strong background in electronic test equipment and principles of electric circuits
• Good understanding and application of standard principles, theories, concepts and techniques in electric propulsion
• Strong background in scripting and programming languages, specifically Python
• Experience developing and maintaining thrust stands and plasma diagnostics
• Experience developing and operating vacuum chambers including operating support equipment such pumps, RGAs, and leak detectors
• Experience in test equipment build‑up and test operations
• Demonstrated proficiency with CAD software and ability to learn new software tools

• Experience with testing Hall thrusters
• Experience with Design of Experiments (DOE)
• Experience designing, writing, executing, and documenting flight hardware test campaigns
• Experience with finite element analysis for electromagnetic fields and/or fluid flow
• Experience with Siemens NX/Teamcenter, fluid schematics, Geometric Dimensioning and Tolerance (GD&T)

• Base salary range for this role is $90,000 - $135,000 + equity in the company
• Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
• Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team…
