Avionics Systems Engineer

Join to apply for the Avionics Systems Engineer role at K2 Space Corporation
.

K2 is building the largest and highest‑power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by $450M from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others – with an additional $500M in signed contracts across commercial and U.S. 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.

We’re a team that believes the future lies in building large, high‑powered satellites that can handle multiple orbits. With multiple launches planned through 2026 and 2027, we’re building bigger to develop the solar system and become 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 groundbreaking Series C space startup, we’d love for you to apply.

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.

• 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 manage 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.

• 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.

• 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,…
