Senior Solar Design 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">Critical to achieving K2's vision of deploying at scale across MEO, GEO, cis-lunar, and deep space are the solar arrays.
