RF Antenna Engineer

K2 Space • Los Angeles, CA

7h • $110,000 - $170,000

About The Position

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.

You will be responsible for the test & measurement of radiofrequency (RF) and microwave electronics to be hosted on some of the largest, most powerful, rapidly designed and rapidly manufactured satellites ever deployed in space. In your first 6 months you will develop the RF test and measurement infrastructure required to integrate and test new RF electronics and antennas for use in software defined radio (SDR) systems for satellite communications and beyond. You will work with a multidisciplinary team of antenna, RF, field programmable gate array (FPGA), digital signal processing (DSP), software, mechanical, and electrical engineers in order to prototype your systems and refine your designs. In your first two years you will have contributed to developing cutting-edge RF systems that will fly in space.
