About the role
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.
K2 Space's standard text
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
The software team at K2 is building our stack primarily in Rust because we believe modern programming languages should be fun, as well as correct. We see Rust as a key enabling technology that allows us to be more effective as software engineers across the entire stack whether that is contributing to the GNC algorithms, application software on flight computers, embedded software on microcontrollers, and many things in-between.
As a part of the team, you will be responsible for the development and verification of the software used to fly some of the largest spacecraft that have ever been flown. You will be able to write mission-critical code that controls propulsion systems, attitude control systems, and power systems to ensure safe and reliable operation of the vehicle. In your first 6 months you will develop core pieces of the software architecture including the strategies for fault tolerance, real-time control, and telemetry downlink.
In your first year you will implement larger software systems and begin verifying your code using both software and hardware in the loop simulators. In your first two years you will operate your code on multiple spacecraft, demonstrating robust performance in demanding missions.
Responsibilities
- Create software architecture for real-time, fault tolerant control of a 20kW+ spacecraft
- Develop software applications for control of spacecraft subsystems, including propulsion, guidance/attitude control, thermal, power, and communications systems
- Design and implement state machines for robust operation of the spacecraft
- Author drivers for microcontroller peripherals and external sensors.
- 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 the spacecraft subsystems
- Build and maintain infrastructure to increase reliability when developing and testing software
Qualifications
- Bachelor's degree in computer science, computer engineering, electrical engineering, math, or a STEM discipline or 3+ years of professional experience in software engineering
- Development experience in C/C++ or Rust
Nice to Have
- Experience with spacecraft flight software development
- Fluency with Linux systems programming and driver development
- Experience with continuous integration and continuous delivery systems
- Experience working with hard real-time embedded systems (bare-metal or RTOS)
- Experience authoring no_std systems in Rust
- Basic knowledge of electronics, computer architecture, and control systems
- Experience developing or working with state machines
- Experience with software verification and testing methods
- Experience with software and network performance analysis and debugging
- Experience working in Rust production environments
- Experience with fault tolerant software design and implementation
- Experience defining and creating test systems for both hardware-in-the-loop and hardware-out-of-the-loop
Compensation and Benefits:
- Base salary range for this role is $123,000 - $170,000 + 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
