Proposal Lead

About Poseidon Aerospace Poseidon Aerospace builds and operates unmanned planes for commercial logistics and defense missions. Our two full‑size fixed‑wing platforms - Heron, a seaplane, and Egret, a STOL aircraft - can carry two tons of payload over a thousand nautical miles. We are headquartered in San Francisco with satellite offices in Washington, DC and Maine. About the role Proposals are how Poseidon wins contracts, and contracts are how Poseidon builds aircraft. We're looking for a Proposal Lead to own that function from first response to submission and build the infrastructure that scales with us.

You will spend the majority of your time crafting the proposals that drive Poseidon’s growth Own proposal responses end‑to‑end as primary author, project manager, and final set of eyes before submission Produce white papers, quad charts, and concept briefs that reach customers before a solicitation drops and shape how they think about the problem Poseidon solves Run color team reviews, manage schedules, and deliver compliant packages on time with a small team and no inherited process Build the proposal infrastructure from scratch: content libraries, writing schedules, reusable prose, and documentation standards, with no bureaucracy slowing you down Establish how Poseidon tells its story to Government customers and refine that story with every submission Work directly with our engineering team and flight operations team to pull technical content and translate it for Government audiences Required Experience personally leading proposal submissions across multiple government contracting efforts, from RFP release through delivery Strong technical writing skills: you can translate complex engineering into clear, specific narrative without genericizing it Working knowledge of FAR/DFARS and proposal compliance requirements Experience developing compliance matrices, managing submission schedules, and owning document configuration Technical literacy in aerospace, autonomy, aviation, or adjacent engineering domains.
