Are you a strategic storyteller who thrives on balancing structure with creativity?

BerryDunn is seeking a proactive, detail-oriented, and success-oriented Senior Proposal Writer to join our growing Business Development team. In this role, you will lead the development of high-impact proposals that help drive the firm’s growth—working collaboratively and aligning to best practices to craft compelling, compliant, and visually engaging content that reflects our firm’s value and culture.

Our ideal candidate will produce high quality documents that blend templated structure with custom messaging— someone who is organized and adaptable, with the confidence to navigate structured processes, as well as creativity to push boundaries. In this role, you will manage multiple priorities and deadlines with professional poise, communicate clearly and effectively, and continually seek feedback to improve work quality and efficiency.

This is more than just a writing role—it’s a chance to shape how BerryDunn tells its story, wins meaningful work, and makes a lasting impact for our clients. This position reports to a Business Development Senior Manager and can be based in our Portland, ME office, another BerryDunn location, or remotely in select cases.
