K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M 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 planned through 2026 and 2027, we're Building Bigger 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 C space startup, we’d love for you to apply.
The Role
You will be responsible for simulating and verifying the software used to fly and orchestrate the behavior of some of the largest satellites that have ever been flown, using both hardware-in-the-loop and hardware-out-of-the-loop testing. Where needed, you will be able to step into different parts of the software stack to drive solutions end-to-end and even make changes to vehicle control software.
In your first 6 months you will generalize simulation software architecture to allow testing and designing multiple spacecraft, demonstrating robust performance in demanding missions. In your first year you will design many-agent simulations and design tools for operating entire constellations of satellites, informing critical company decisions.
Responsibilities
- Create and maintain simulation software infrastructure for our 20kW+ spacecraft
- Develop physics-based software models of spacecraft subsystems, including propulsion, attitude control, power, and communications systems.
- Perform analyses of constellation capabilities and performance to support business and engineering decisions, including network coverage and beam planning.
- Create and utilize robust tools to allow for rapid deployment of quality code.
- Perform data analysis and anomaly investigation to identify and resolve on-orbit problems.
- Support integration and testing of spacecraft subsystems.
Qualifications
- Bachelor's degree in physics, aerospace/mechanical/electrical engineering, computer science, math, or a STEM field or 3+ years of professional experience in software engineering or relevant professions
- Development experience in Rust, C++, or similar compiled language
- Experience using scientific Python (NumPy, SciPy, etc.), Julia, MATLAB, or similar
- Coursework or experience in numerical methods, ordinary differential equations, and mechanics
Nice to Have
- 3+ years of professional experience in software engineering
- Master’s or PhD in physics, aerospace engineering, or a STEM field
- Experience working in Rust production environments
- Experience defining and creating simulation systems
- Experience with Monte Carlo simulations and probability/statistics
- Experience with linear algebra, controls, and/or orbital mechanics
- Basic knowledge of electronics, Linux, and computer architecture
- Experience with space communication modeling (RF, ground stations)
- Experience with continuous integration and continuous delivery systems
Compensation and Benefits:
- Base salary range for this role is $123,000 - $200,000 + 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 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

The Role
As a Senior Navigation & Guidance engineer, you will be a core driver of the overall spacecraft GNC architecture. You will execute detailed trade studies to find new and novel ways to implement the spacecraft’s guidance, attitude control, and attitude and orbit estimation systems. In the first 3 months, you will support the development of the control infrastructure, from discrete filter design in the time domain to thorough analysis in the frequency domain. Additionally, you will support the development of autonomous orbit raise for a vehicle to MEO and the associated navigation to support an autonomous orbit raise. In the first 6 months, you will own and execute the Verification and Validation plan for the GNC stack, driving the system to flight readiness via a robust and thorough analysis of vehicle performance in both nominal and off nominal environments. This push for flight readiness will motivate thorough analysis, leading to updates to both the GNC stack and the K2 6-DOF simulation. The expectation is that all GNC team members commit code to the 6-DOF sim as well as owning a portion of the GNC flight software.
In the first year, you will support launch and on orbit operations of the first full demonstration of the K2 spacecraft bus – the Mega. In parallel, you will support the block 2 upgrades of the GNC stack and 6-DOF sim, taking lessons learned from on orbit operations to increase the fidelity of the simulation and the vehicle performance of the GNC stack.
Responsibilities
- Work with other engineering leads to develop and validate a novel high level vehicle architecture
- Develop novel algorithms for precise pointing of very large, flexible structures in earth orbit and beyond
- Develop novel slewing algorithms of very large, flexible structures in earth orbit and beyond
- Develop simulation and modeling tools to support vehicle and GNC trade studies. This includes mission design, controls analysis, and 6-DOF simulation development.
- Contribute to building the GNC organization by recruiting, hiring, and mentoring other engineers
Qualifications
- Experience with GNC actuator or sensor sizing, selection, and system design
- Experience with implementing attitude control and/or estimation algorithms on spacecraft
- Experience with verification and validation of GNC flight software in an integrated environment, leveraging 6-DOF simulation and HITL testing.
- Experience with Python, Julia, C/C++, or Matlab for algorithm development, implementation, and simulation
Nice to Have
- Experience with early-stage spacecraft conceptual design, i.e. “clean sheet” design work
- Experience with control algorithm development
- Experience with reaction wheel, control moment gyroscope, or thruster sizing and algorithm implementation
- Experience with navigation, specifically Extended Kalman Filters
- Experience with trajectory analysis, modeling, and mission design
- Experience with Rust software development
Compensation and Benefits:
- Base salary range for this role is $160,000 - $235,000 + 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
