Job Description

RF Test Engineer

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

You will own the success of Avionics testing involving the computing, data acquisition, RF, and power subsystems that are key to our satellite operation. In your first 6 months, you will be pivotal in developing production quality test hardware and software to deliver flight avionics through ATP and QTP for the first Mega satellite constellation. You will be working alongside the Electrical and RF Engineering teams to interface with Avionics hardware, validate prototype designs, define test requirements, and design test infrastructure to meet critical programmatic milestones such as delivery of flight hardware to vehicle integration. In your first year, you will lead multidisciplinary test campaigns, root cause investigations, and production improvements to ensure reliability and scalability.

Responsibilities

• Design and fabricate test hardware, harnessing, and test systems to support electrical and RF development testing
• Develop modular, reusable test automation software and drivers in Linux, Python, C++, Rust, etc.
• Execute development and production tests to meet internal and external customer needs
• Lead satellite subsystem test campaigns from kickoff, through test report, and beyond
• Develop data acquisition, control, and instrumentation systems to test at the integrated level
• Own the project management of multiple test assets and acceptance testing of flight avionics including upgrades to support hardware lifecycle
• Design device simulators deployed across component subsystem and HITL testbeds
• Collaborate with a cross-functional team to establish product requirements, testing methods, and project test schedules

Qualifications

• Bachelor's degree in electrical, computer, or other relevant engineering discipline or any equivalent combination of education and experience
• 2+ years of experience with test hardware design and software management
• Strong programming abilities (Python, C++, Rust)
• Experience with RF test equipment such as vector network analyzers (VNA), spectrum analyzer, etc.

Nice to Have

• Experience with data acquisition, controls, and dedicated test equipment
• Familiarity with SMC-S-016 or MIL-STD-810 testing methods, including vibration, shock, and thermal testing
• Experience with software-defined radio hardware development, including high-speed RF data converters (digital to analog and analog to digital converters), clock trees, and data converter interfaces
• Experience with calibration of RF equipment, dataflow testing, and radiated end-to-end validation
• Experience with the practical application of serial and ethernet communications
• Understanding of the failure modes of electrical systems in space environments
• Demonstrated ability to own electrical hardware test systems within an integrated engineering team
• Creative problem solver that can balance schedule, resource, and technical constraints

Compensation and Benefits:

• Base salary range for this role is $100,000 - $150,000 + 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.
