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
As a Hardware-In-The-Loop (HITL) Testbed Engineer, you’ll own designing, implementing, and maintaining critical test assets integrating flight-like hardware and high-fidelity simulation. You will support critical tests validating system design, verifying flight and ground software, and operations related in active missions in space. Your attention to detail and preparation will ensure that the flatsat testbed is ready for tasks that could directly impact mission success. Knowing how to scale these testbeds using automation and flexible configuration will enable teams to have accurate results and parity with flight vehicles with various mission objectives.
Responsibilities
- Work with responsible engineers and software engineers to design a high-fidelity vehicle testbed ensuring high technical rigor and associated documentation.
- Operate the HITL testbed in support of system validation, verification, and investigations, including on-orbit operations.
- Receive, integrate, and test flight representative hardware into HITL testbeds.
- Collaborate with design and systems engineers to create and build hardware simulation equipment.
- Own, maintain, and document HITL table configuration and build out, including the supporting GSE racks.
- Create and release harness drawings for required ground support and test equipment.
- Investigate and troubleshoot testbed issues and drive further actions to improve future designs.
- Design, maintain, and operate HITL racks deployed to customers for integration.
- Support training events for mission operators for constellation management.
Qualifications
- Bachelor’s degree in electrical, aerospace, mechanical, computer, or other engineering discipline
- 2+ years of experience in an integration/test/automation engineering role (includes internships and design/build/compete extracurricular projects)
- Hands-on experience with HITL or Flatsat software verification testbeds.
- Experience designing, building, and maintaining test racks and harnessing.
- Experience testing and troubleshooting integrated avionics systems and their related components.
- Hands-on experience using electrical test equipment (PSU, Oscilloscope, DMM, etc.) and with ESD sensitive equipment.
- Excellent conflict resolution and negotiation skills
Nice to Have
- Proficient in Python and/or Rust
- Experience with Linux systems
- Experience managing contractual interfaces (e.g. customer, launch vehicle)
- Experience with containerized solutions like Docker.
- Desire to continually raise the bar of “good enough” and innovate novel solutions for scaling HITL.
Compensation and Benefits
- Base salary range for this role is $100,000 - $140,000 + 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.
