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 responsible for system design, analysis, testing and integration of avionics on some of the largest, most powerful, rapidly designed and manufactured satellites. You will have the unique opportunity to collaborate with a cross functional team of engineers to make impactful architecture trades, design new spacecraft hardware, and manage the overall avionics system implementation. You will be the Responsible Engineer for Avionics interfacing, harnessing, instrumentation, RF components, and GNC actuators. You will help establish production test requirements and support vehicle avionics integration to enable high-rate production and constellation launch cadence. 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
Support spacecraft integration testing, production issue dispositions, troubleshooting failures, and managing overall spacecraft risk
Design, develop and build Avionics production infrastructure
Write modular, reusable test, analysis, and automation software in Python and Rust
Effectively manage and communicate project plan, milestones, and schedule execution

Qualifications

Bachelor’s degree in aerospace, mechanical, or electrical engineering or any equivalent combination of education and experience
2+ years of experience in the documentation, development, testing, and integration of space-grade avionics systems
Ability to work in a fast-paced and high velocity start-up atmosphere
Creative problem solver that can assess risk and make collaborative design and development decisions

Nice to Have

Hands-on experience with environmental testing for space electronics and harnessing such as thermal, thermal vacuum, vibration, shock, radiation, and EMI/EMC testing per SMC-S-016
Competence with electrical test equipment (multimeters, oscilloscopes, network analyzers, etc.)
Strong presentation experience in highly technical design forums and reviews (Preliminary Design Reviews, Critical Design Reviews, Flight Readiness Reviews, etc.)
