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

Qualifications

Bachelor's degree in English, communications, journalism, engineering, a science discipline, or related field

5+ years of professional technical writing experience, ideally in aerospace, defense, or another complex engineering domain

Demonstrated experience writing and coordinating proposals, including responses to US government solicitations

Exceptional written and verbal communication skills, with a portfolio that shows the ability to make complex technical content clear and persuasive

Ability to interview subject-matter experts and independently produce accurate technical content from sparse or rough inputs

Ability to manage multiple documents and deadlines simultaneously in a fast-paced, autonomously driven, and demanding startup atmosphere

Nice to Have

Experience with spacecraft, satellite, or payload programs

Familiarity with government contracting vehicles, CDRLs, DIDs, and proposal compliance practices

Proficiency with graphics and layout tools (Adobe InDesign, Illustrator, or equivalent)

Experience building and maintaining content libraries, style guides, and documentation templates

APMP certification or equivalent proposal-management credential

Additional Requirements

Ability to travel up to 25% of the time

Active Top Secret or Top Secret SCI clearance preferred; willing to pursue and maintain a clearance if not already cleared

Ability to work irregular business hours to support proposals or critical project timelines

Compensation and Benefits

Base salary range for this role is $100,000 - $140,000 + equity in the company

Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level

Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks

If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!

If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.

Export Compliance

As defined in the ITAR, “U.S. Persons” include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a “U.S. Person.”

The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR).
