Technical Writer

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 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 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.

The Role

As a Technical Writer at K2 Space, you will own the words that win work and deliver it. You'll support the full arc of the business — from early business development and capture, through compliant and compelling proposals, to the technical data packages and deliverables we owe customers on contract. You'll translate complex spacecraft, payload, and mission engineering into clear, accurate, and persuasive documentation for commercial and US government audiences. Working shoulder-to-shoulder with program managers, mission engineers, and subject-matter experts, you'll turn raw technical inputs into polished narratives, manage document production under aggressive deadlines, and raise the bar on how K2 communicates in writing across every phase of a program.

Responsibilities

• Write, edit, and produce content across the full business lifecycle — business development and marketing collateral, white papers, proposals and proposal volumes, and on-contract technical deliverables

• Lead proposal writing and coordination: interpret solicitations (RFPs, RFIs, BAAs), build compliant outlines and compliance matrices, draft and edit technical and management volumes, and drive documents to on-time submission

• Distill inputs from mission engineers, program managers, and other SMEs into clear, accurate, and compelling narratives tailored to the audience

• Partner across the organization to ensure documentation is accurate, consistent, and delivered on schedule under competing priorities &lt
