Proposal Strategist

WindBorne Systems is supercharging weather forecasts with a unique proprietary data source: a global constellation of next-generation smart weather balloons targeting the most critical atmospheric data. We design, manufacture, and operate our own balloons, using the data they collect to generate otherwise unattainable weather intelligence.

Our mission is to eliminate weather uncertainty, and in the process help humanity adapt to climate change, be that predicting hurricanes or speeding the adoption of renewables. We are building a future in which the planet is instrumented by thousands of our microballoons, eliminating gaps in our understanding of the planet and giving people and businesses the information they need to make critical decisions. The founding team of Stanford engineers was named Forbes 2019 30 under 30 and is backed by top-tier investors, including Khosla Ventures and Footwork VC.

WindBorne has won federal contract awards every year since our founding, and our written deliverables—proposals, white papers, and technical documentation—are core to that growth across federal, international, and commercial markets. We're hiring a Proposal Strategist to join our proposals team and help carry that work forward. Reporting to the Proposal Manager, you'll be a writer first, a project manager second, and a curious researcher throughout. The ideal candidate is an exceptional early-career writer ready to take on real ownership fast—within your first six months, you should be ready to own a proposal end-to-end.

We want to talk if you’re excited about translating technical depth into compelling prose for customers ranging from federal defense and civilian agencies to international weather services to commercial energy traders. You don't need a background in atmospheric science, meteorology, or aerospace, but you do need a real appetite to learn the material. Our best writing comes from people who got curious enough to ask the next question! To apply, please submit through our application portal and also send a short email to proposalhiring@windbornesystems.com with a brief description of a piece of writing you're proud of and why. We read every one.

Responsibilities

• Proposal Drafting: Compose bespoke narrative for federal, international, and commercial proposals, interweaving technical reference materials and original prose to produce compelling, compliant deliverables.

• Schedule & Deliverable Management: Own proposal timelines, track milestones, and keep cross-functional contributors on pace through submission.

• SME & Review Coordination: Partner with engineering, product, and growth teams to extract technical content, manage review cycles, and incorporate feedback efficiently.

• Research: Investigate agencies, solicitations, competitors, and regulatory landscapes to inform proposal strategy and messaging.

• Editing & Compliance: Perform proofreading, content checks, and formatting compliance on your own work and on team deliverables.

• Content Library Development: Help build out and maintain WindBorne's reusable content library—past performance, capabilities language, technical descriptions, boilerplate—so our writing scales smarter, not harder.

Skills and Qualifications

• 1-3 years of professional experience, with a strong portfolio of professional writing—published, professional, or otherwise demonstrably polished

• Project management or coordination experience that proves you can hit deadlines without dropping balls

• A sharp, adaptable writer who can shift register across audiences. Federal, international, and commercial customers each have their own conventions, and you should be eager to learn them

• Skilled at navigating feedback from technical reviewers while keeping the final prose clear and compelling

• Insatiable curiosity. Our work touches atmospheric science, AI, hardware, defense, and climate. You won't be expected to be an expert in any of these on day one, but you should be the kind of person who actually wants to learn

• A strong collaborator who thrives on building things with and for other people. Much of this role is about making the proposals team—and WindBorne's written content as a whole—more organized, more reusable, and more impactful over time

• Comfort using AI writing tools thoughtfully as part of your drafting and research workflow
