Proposal Writer

Do you enjoy transforming complex technical information into clear, compelling, and compliant proposal responses?

BerryDunn is seeking a proactive, detail-oriented, and motivated Proposal Writer to join our growing Business Development team. In this role, you will lead the development of proposals from initiation through submission, partnering with business development professionals and subject matter experts to create compelling, compliant, and persuasive content that reflects BerryDunn's expertise, value, and culture.

Our ideal candidate is a strong writer who can quickly understand complex subject matter and translate technical concepts into clear, client-focused messaging. You are organized, adaptable, and comfortable managing multiple deadlines and competing priorities while maintaining a high standard of quality, accuracy, and attention to detail.

You are comfortable leveraging existing resources and proven content while tailoring responses to address unique client needs, and you take pride in producing polished work, communicating effectively with contributors, and delivering results in a fast-paced, deadline-driven environment.

This is more than just a writing role. It is an opportunity to shape how BerryDunn communicates its expertise, supports meaningful client work, and pursues new opportunities. As you grow in the role, you will continue to strengthen your proposal management, collaboration, and content development skills while contributing to increasingly complex pursuits and contributing to a culture of continuous improvement and shared success.
