Avionics Systems Engineer

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.

The Role 

You will be the Responsible Engineer for system design, analysis, testing and integration of Avionics with specialized focus on spacecraft charging, radiation, EMI, and/or RF. You will have the unique opportunity to partner with a cross functional team of engineers to make impactful architecture trades, design new spacecraft hardware, and characterize the overall Avionics System performance on some of the largest, most powerful satellites. You will help establish production test infrastructure and qualify the spacecraft for the demanding environments of MEO and GEO. In your first two years, you will have qualified hardware for flight, completed Avionics integration on the satellite bus, and flown your first spacecraft. 

Responsibilities 

• Serve as Responsible Engineer for Avionics system design, performance, and hardware across the computing, power system, instrumentation, RF components, GNC sensors, and harnessing on the satellite bus 
• Collaborate closely within the cross functional Engineering teams to capture requirements, lead design trades, and integrate the design into the spacecraft systems 
• Create and update technical documentation including system diagrams, schematics, interface control documents, procedures, test/anomaly reports 
• Execute Avionics component and system testing on flight hardware through development acceptance, qualification, and integration testing
