Position Description:

At CGI, we’re helping shape the future of national security, space, and defence through technology and collaboration that truly make a difference. As a Proposal Writer within our Space, Defence and Intelligence (SDI) business, you’ll craft compelling proposals that influence major programmes across the UK and beyond. Your words will capture innovation, precision and partnership—ensuring CGI’s unique capabilities and expertise stand out in a competitive landscape. This role offers the opportunity to be at the heart of our mission-critical bids, working with experts across disciplines to deliver solutions that keep the nation safe and our clients at the forefront of digital transformation.

CGI was recognised in the Sunday Times Best Places to Work List 2025 and has been named one of the World's Best Employers by Forbes magazine. We offer a competitive salary, excellent pension, private healthcare, plus a share scheme (3.5% + 3.5% matching) which makes you a CGI Partner not just an employee. We are committed to inclusivity, building a genuinely diverse community of tech talent and inspiring everyone to pursue careers in our sector, including our Armed Forces, and are proud to hold a Gold Award in recognition of our support of the Armed Forces Corporate Covenant. Join us and you’ll be part of an open, friendly community of experts. We’ll train and support you in taking your career wherever you want it to go.

Due to the secure nature of the programme, you will need to hold UK Security Clearance or be eligible to go through this clearance. This is a hybrid position.

Your future duties and responsibilities:

In this role, you will be instrumental in shaping CGI’s most strategic and high-value bids, producing engaging, client-focused proposals that showcase our innovation, capability, and value. You’ll collaborate closely with bid managers, technical SMEs and subject matter experts to translate complex ideas into clear, persuasive narratives that resonate with clients. You’ll also contribute to continuous improvement in proposal quality and mentor others in best practice writing standards—helping elevate the overall impact of our submissions.

You will take ownership of the full proposal process, from storyboarding through to submission, ensuring each bid reflects CGI’s excellence and creativity. Working within a supportive team environment, you’ll have the opportunity to grow your expertise, influence major defence and space programmes, and play a key role in CGI’s ongoing success.

Key responsibilities include:

Lead & Deliver: Take full ownership of high-quality proposal documentation from storyboarding to final submission.

Collaborate & Innovate: Work with SMEs and technical experts to translate complex ideas into clear, persuasive content.

Review & Enhance: Support proposal reviews (Pink, Red, Gold) to strengthen bid quality and consistency.

Develop & Mentor: Guide and coach other writers and team members in effective proposal techniques.

Create & Reuse: Produce compelling case studies and reusable content to strengthen future bids.

Required qualifications to be successful in this role:

You should have:

Proven experience in proposal writing within IT, systems integration, or defence sectors.

Strong ability to synthesise complex technical content into concise, client-focused language.

Excellent written and verbal communication and presentation skills.
