Senior MMIC Design Engineer

<div class="content-intro">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.</div>About the Role  We are looking for a Senior MMIC Design Engineer to develop high-performance RF and millimeter-wave integrated circuits for next-generation satellite communication systems. You will own MMIC designs from architecture and technology selection through tapeout, characterization, and product integration. Responsibilities  <ul> <li>Design and develop power amplifiers (PAs), low-noise amplifiers (LNAs), and RF switches in GaAs and GaN technologies. </li> <li>Own designs from architecture and topology selection through schematic design, layout, EM simulation, tapeout, and silicon/MMIC characterization. </li> <li>Optimize circuits for output power, efficiency, linearity, noise figure, bandwidth, gain, and robustness. </li> <li>Perform RF and electromagnetic simulations, including passive structures, matching networks, interconnects, and package/interface effects. </li> <li>Develop test plans and characterize MMICs using RF and millimeter-wave laboratory equipment. </li> <li>Correlate measured performance with simulation and drive design improvements. </li> <li>Work closely with RF systems, antenna, packaging, and transceiver IC teams to define interfaces and enable system-level integration. </li> <li>Contribute to technology evaluation, architecture trades, design methodology, and development of MMIC capabilities from the ground up. </li> </ul> Qualifications  <ul> <li>MS, or PhD in Electrical Engineering or a related field. </li> <li>5+ years of experience in designing RF/millimeter-wave MMICs in GaAs and/or GaN technologies. </li> <li>Demonstrated design experience with PAs, LNAs, and/or RF switches, with deep expertise in at least one of these areas. </li> <li>Strong understanding of RF fundamentals including impedance matching, stability, noise, linearity, power handling, and nonlinear behavior. </li> <li>Experience with Cadence, Keysight ADS, EM simulation tools, or equivalent RF/MMIC design environments. </li> <li><span da
