Job description

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.

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
