From the original posting

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.

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

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.

Qualifications

MS, or PhD in Electrical Engineering or a related field.
5+ years of experience in 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 the 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 a fast-paced environment and building new RF/MMIC capabilities from the ground up.

Compensation and Benefits:

Base salary range for this role is $170,000 – $250,000 + 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!
