You will bring creativity and constructive challenge to the proposal process, translating complex technical information into concise, engaging client-facing content and independently developing non-technical responses where appropriate.

Supported by an experienced collaborative team, you will also contribute to proposal reviews, mentor colleagues and create reusable case studies and content that strengthen future bids and support CGI's continued growth. ~ Lead
