About the Role

You will lead proposal and capture work from teaming strategy and solicitation response through final submission, while translating complex technology into clear technical narratives, product documentation, and go-to-market content. The work crosses engineering, business development, contracts, and leadership. The standard is simple: understand the technology, make the case clearly, and get high-quality work out the door on time.

What We Value

• Care about the details — sloppy work costs us later, so do it right the first time.
• Move with urgency — every week matters more than it feels like it does.
• Be responsible for the outcome, not just the task; if it is not working, it remains your problem until it is fixed.
• Assume good intent — disagree openly, then commit fully once a call is made.

• Review and edit documentation to maintain a high standard of quality.
• Identify, triage, and resolve gaps in existing documentation.
• Maintain style guides and writing best practices across all content types.

General

• Prioritize, adapt, and operate effectively in unstructured, fast-moving startup environments.
• Manage and coordinate internal and external stakeholders to keep deals and projects on track.
• Stay curious and enthusiastic about learning and communicating new technology and concepts.

Minimum Qualifications

• 5+ years of experience in business, government, government contracting, or defense contracting, with direct experience writing or managing proposals.
• Excellent verbal and written communication skills, with the ability to distill complex ideas into digestible concepts for stakeholders at every level, and to produce large, high-quality documents on short timelines.
• Ability to spot technical or functional gaps and propose solutions using internal or external resources.
• Comfort working in fast-paced, deadline-driven environments across varied stakeholder groups, including design, engineering, program management, security, supply chain, and finance.
• A self-starter who can rapidly find information without clear guidance.
• Outstanding writing and editing skills across both persuasive (proposal) and technical (documentation) formats.

• 6+ years of experience in capture, proposal writing, or government contracting.
• Familiarity with traditional and non-traditional government contracting vehicles.
• Significant experience with government solicitation processes (RFP, RFI, RFQ, BAA, OTA, etc.).
• Experience writing for a startup or fast-scaling company, balancing structured proposal work with more flexible content needs.
• Active security clearance.
