K2 Space is building the largest and highest-power satellites ever flown, backed by over $1 billion in total funding and $1 billion in signed contracts across commercial and US government customers. The company is mass-producing high-power satellite platforms for missions from LEO to deep space, with multiple launches planned for 2027 and scaling to 100 satellites per year.
You will join as a Senior MMIC Design Engineer responsible for developing high-performance RF and millimeter-wave integrated circuits for next-generation satellite communication systems. You will own MMIC designs end-to-end, from architecture and technology selection through tapeout, characterization, and product integration.
Key responsibilities include:
- Design and develop power amplifiers (PAs), low-noise amplifiers (LNAs), and RF switches in GaAs and GaN technologies
- Own designs from architecture and topology selection through schematic design, layout, EM simulation, tapeout, and silicon/MMIC characterization
- Optimize circuits for output power, efficiency, linearity, noise figure, bandwidth, gain, and robustness
- Perform RF and electromagnetic simulations, including passive structures, matching networks, interconnects, and package/interface effects
- Develop test plans and characterize MMICs using RF and millimeter-wave laboratory equipment
- Correlate measured performance with simulation and drive design improvements
- Work closely with RF systems, antenna, packaging, and transceiver IC teams to define interfaces and enable system-level integration
- Contribute to technology evaluation, architecture trades, design methodology, and development of MMIC capabilities from the ground up
This is a high-growth Series D-funded company building spacecraft and RF capabilities from the ground up in a fast-paced environment.
REQUIREMENTS:
- MS or PhD in Electrical Engineering or related field
- 5+ years of experience designing RF/millimeter-wave MMICs in GaAs and/or GaN technologies
- Demonstrated design experience with PAs, LNAs, and/or RF switches, with deep expertise in at least one of these areas
- Strong understanding of RF fundamentals including impedance matching, stability, noise, linearity, power handling, and nonlinear behavior
- Experience with Cadence, Keysight ADS, EM simulation tools, or equivalent RF/MMIC design environments
- Hands-on experience with RF/mmWave characterization and equipment such as VNAs, spectrum analyzers, signal generators, power meters, and load-pull systems
- Experience taking designs through tapeout and measured hardware validation
PREFERRED QUALIFICATIONS:
- Experience with wideband RF/mmWave circuit design techniques
- PA experience spanning high efficiency, high linearity, and broadband operation
- Experience designing circuits into Ka-band and higher millimeter-wave frequency ranges
- Familiarity with MMIC packaging, RF module integration, thermal considerations, and antenna/array interfaces
- Experience developing MMICs for phased arrays, satellite communications, aerospace, or other high-reliability applications
- Experience working in fast-paced environments and building new RF/MMIC capabilities from the ground up
