Senior Post-Silicon Validation Engineer New Los Angeles, CA

K2 Space Corporation; Los Angeles (CA); Hybrid; USD 140,000 - 210,000; Full time

Job summary

K2 Space Corporation in Los Angeles is seeking a hands-on Senior Post-Silicon Validation Engineer to own silicon bring-up, characterization, and system-level validation of complex mixed-signal SoCs, enabling a smooth transition from validated silicon into product integration.

You will define the validation strategy, build test and validation capability from the ground up, and lead execution from first silicon through product readiness.

Responsibilities

• Own post-silicon validation strategy, test planning, execution, coverage, and sign-off.
• Lead first silicon bring-up across power, clocks, debug interfaces, processor/memory subsystems, peripherals, and high-speed interfaces.
• Define and execute the validation strategy and readiness criteria needed to enable product integration, ensuring silicon, firmware, test infrastructure, and system interfaces are ready for integration.
• Own system-level test planning and execution, including functional, performance, stress, and corner-case testing.

Job description

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.
