Principal Avionics Systems Engineer

About this role

<div class="content-intro"><p class="p1">K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by <a href="https://www.forbes.com/sites/aliciapark/2025/12/11/this-startup-is-building-huge-satellites-for-an-underused-interstellar-sweet-spot/?ctpv=searchpage">$450M</a> from leading investors including Altimeter Capital, Redpoint Ventures, T. Rowe Price, Lightspeed Venture Partners, Alpine Space Ventures, and others <span class="s1">– </span>with an additional $500M 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.<span class="Apple-converted-space"> </span></p> <p class="p1">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.<span class="Apple-converted-space"> </span></p> <p class="p1">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. <span class="TextRun SCXW79998266 BCX0" lang="EN-US" data-contrast="auto"><span class="NormalTextRun SCXW79998266 BCX0">If you are a motivated individual who thrives in a fast-paced environment and </span><span class="NormalTextRun SCXW79998266 BCX0">you're</span><span class="NormalTextRun SCXW79998266 BCX0"> excited about contributing to the success of a groundbreaking Series C</span><span class="NormalTextRun SCXW79998266 BCX0"> space startup, </span><span class="NormalTextRun SCXW79998266 BCX0">we’d</span><span class="NormalTextRun SCXW79998266 BCX0"> love for you to apply.</span></span><span class="EOP SCXW79998266 BCX0" data-ccp-props="{"335559738":240,"335559739":240}"> </span></p></div><p><strong><span data-contrast="auto">The Role</span></strong><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><span data-contrast="auto">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.</span><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <p><strong><span data-contrast="auto">Responsibilities</span></strong><span data-ccp-props="{"335559738":240,"335559739":240}"> </span></p> <ul> <li><span class="TextRun SCXW220382721 BCX0" lang="EN" data-contrast="auto"><span class="NormalTextRun SCXW220382721 BCX0">Serve as Responsible Engineer for </span><span class="NormalTextRun SCXW220382721 BCX0">A</span><span class="NormalTextRun SCXW220382721 BCX0">vionics </span><span class="NormalTextRun SCXW220382721 BCX0">s</span><span class="NormalTextRun SCXW220382721 BCX0">ystem design, performance, and hardware across the computing, power system, instrumentation, </span><span class="NormalTextRun SCXW220382721 BCX0">RF components, </span><span class="NormalTextRun SCXW220382721 BCX0">GNC sensors, and harnessing on the satellite bus</span></span><span class="EOP SCXW220382721 BCX0" data-ccp-props="{"335559738":240}"> </span></li> <li><span data-contrast="auto">Collaborate closely within the cross functional Engineering teams to capture requirements, lead design trades, and integrate the design into the spacecraft systems</span><span data-ccp-props="{}"> </span></li> <li><span data-contrast="auto">Create and update technical documentation including system diagrams, schematics, interface control documents, procedures, test/anomaly reports</span><span data-ccp-props="{}"> </span></li> <li><span data-contrast="auto">Execute Avionics component and system testing on flight hardware through development acceptance, qualification, and integration testing</span><span data-ccp-props="{}"> </span></li> <li><span…
