About CND
Computer Network Defence Ltd (CND) is a trusted and growing cyber security business, helping public and private sector clients tackle complex security challenges with confidence. As a certified B Corp, we are committed not only to high standards of professional excellence, but also to doing business in the right way for our people, our community, and the wider world. We combine deep technical expertise with a supportive, collaborative culture, giving our people the chance to do meaningful work, develop their careers, and make a visible impact.
About the Role
We are looking for a proactive and highly organised Bid Writer/Administrator to support the Bid Manager in delivering winning bids, tenders, and framework submissions across the business.
