Senior Proposal Writer

Brillient is seeking an exceptional Senior Proposal Writer who doesn't just produce compliant responses — they produce winning ones. This individual will serve as the cornerstone of our proposal development effort, partnering with capture managers, technical SMEs, and leadership to craft compelling, evaluator-focused narratives that differentiate Brillient in competitive federal procurements. This is a hands-on, high-impact role for a practitioner who thrives in deadline-driven environments, can rapidly absorb complex technical solutions, and knows how to translate dense technical content into prose that scores. You will own proposal volumes end-to-end — from strategy and outline through final production — across FedCiv, Health, DoD, and product/software sales opportunities.

This position follows a hybrid schedule, candidates must be local to the National Capital Region.
