Principal Mixed-Signal Design Engineer, Data Converters

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.

About the Role We are looking for a Principal Mixed-Signal Design Engineer, Data Converters to lead the architecture and development of wideband, high-performance data converters and associated analog front-ends for advanced mixed-signal SoCs. This is a hands-on technical leadership role with significant ownership—from architecture and technology tradeoffs through circuit design, integration, and silicon validation.

• Architect and design high-speed, wideband ADCs and DACs targeting demanding RF and mixed-signal applications.

• Lead converter architecture selection and trade studies, balancing bandwidth, sampling rate, resolution/ENOB, linearity, power, area, and implementation risk.

• Design supporting wideband analog front-ends, including ADC input networks, track-and-hold/sampling circuits, DAC output stages, references, biasing, clocking, and calibration circuitry.

• Develop high-performance circuits in advanced FinFET CMOS technologies and address the unique analog design challenges associated with deeply scaled nodes.

• Own designs from concept and behavioral modeling through transistor-level implementation, layout, verification, and silicon characterization.

• Develop calibration and correction techniques for impairments and work closely with DSP/systems engineers on mixed-signal algorithms.

• Define converter specifications and interfaces in collaboration with systems, RF, digital, package, and verification teams.

• Drive converter integration into complex mixed-signal SoCs, including power, clocking, signal integrity, and physical implementation considerations.<span
