Simulation Software Engineering Intern - Summer 2027

K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.

The rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.

With multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward 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 high-growth Series D-funded company, we'd love for you to apply.

The Role

We're looking for a stellar intern to join our team for a 3 month internship. Working closely with K2 engineers in a highly collaborative environment, you will be responsible for owning a software engineering project end-to-end and supporting actual on-orbit operations of our spacecraft. You will interact with advanced technologies like cyber-physical system simulators, satellite sensors and actuators, build systems, GNC algorithms, and more.

Responsibilities

• Develop physics-based software models for testing control of spacecraft subsystems, including propulsion, guidance/attitude control, thermal, power, and communications systems

• Author drivers for simulation hardware

• Create and utilize robust tools to allow for rapid deployment of quality code

• Perform data analysis and anomaly investigation to identify and resolve software bugs

• Support integration and testing of spacecraft subsystems

Qualifications

• Development experience in Rust, C++, or similar compiled language

• Coursework or experience in numerical methods, ordinary differential equations, mechanics, and electricity and magnetism

Additional Requirements

• Available for a minimum 12-week internship in person at our HQ in Torrance

Nice to Have

• Experience using scientific Python (NumPy, SciPy, etc.), Julia, MATLAB, or similar

• Experience defining and creating simulation systems for both hardware-in-the-loop and hardware-out-of-the-loop testing

• Experience with Monte Carlo simulations and probability/statistics

• Experience with linear algebra, signal processing, controls, and/or orbital mechanics

• Experience with continuous integration and continuous delivery systems

• Experience with Linux systems programming and driver development

• Basic knowledge of electronics, computer architecture, and control systems

Compensation

• Hourly pay range for this non-exempt role is $30 - $40 per hour

• Hourly rate will be based on several factors including, but not limited to: knowledge and skills, education, and experience level

• Housing and travel stipend may also be available

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 unlike any other and non-traditional career twists and turns are encouraged!

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.

Export Compliance

As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.”

The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a “U.S. person” as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.

Equal Opportunity

K2 Space is an Equal Opportunity Employer; employment with K2 Space is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
