Providing audit, tax and advisory services, we empower clients through strategic insight, curiosity, and genuine partnership. And we empower our people with real opportunity, an inclusive culture and work life balance. A true alternative.

With over 5,000 people in the UK, and a presence in 150 global markets, we’re on an ambitious journey, from great to exceptional, and we need the best people to help us achieve our potential. And with that comes the opportunity to help redefine what our industry looks like, and what you want from your career.

Job Description:

MORE THAN YOU EXPECTED

Grant Thornton UK LLP is part of a global network of independent audit, tax and advisory firms, made up of some 58,000 people in over 135 countries. We’re a team of independent thinkers who put quality, inclusion and integrity first. All around the world we bring a different experience to our clients. A better experience. One that delivers the expertise they need in a way that goes beyond. Personal, proactive, and agile. That’s Grant Thornton.

NEW GROUND WON'T BREAK ITSELF.

Every day our teams help people in businesses and communities to do what is right and achieve their goals.

We are looking for a Bids and Pursuits Assistant Manager to join our Bids and Pursuits team on a 6-month fixed-term contract, supporting our Business Risk Services (BRS) practice. We’re keen to find someone who can start soon. If you enjoy working on a variety of proposals, and playing a key role in winning work and growing the business, you’ll fit right in.

You will take charge of the bids process, managing your own proposals from the initial kick-off meeting right through to managing the design process and the tender debrief stages. Working closely with senior colleagues, you will make sure tight deadlines and deliverables are met, and that supporting documents are compelling.

You will work closely with BRS Partners and Directors on proposals for new and existing clients. On larger, strategic pursuits, you’ll help shape the bid strategy and how we position ourselves to win, with the opportunity to develop creative and innovative ways to influence it. AI tools, including our Claude-based proposals tool, are already in place to support you, so more of your time goes into the work that makes the difference. The team has a history of developing internal talent to progress, so you will have the chance to grow your knowledge and build strong working relationships with key stakeholders across the firm.

This is a hybrid role based in the London office, with travel to see stakeholders as needed.

A look into the role

As a Bids and Pursuits Assistant Manager, you will:

• Manage your own proposals, from the arrival of a tender invitation to the final response and presentation
• Work with members of the wider team, owning elements of larger, strategic tender responses
• Produce high-quality documents, writing and reviewing compelling proposals, and providing input at different stages of the proposals process
• Take a hands‑on approach to supporting engagement teams with bid evaluation, project management, document production, meeting and presentation preparation, and process debriefs
• Make the most of our AI tools to produce strong first drafts quickly, freeing up time for strategy on larger pursuits
• Act as a point of contact for general bid‑related queries, including day‑to‑day support for client teams, and bring ideas to influence the proposals process by understanding internal and external stakeholders'' needs

Knowing you're right for us

Joining us as a Bids and Pursuits Assistant Manager, the minimum criteria you’ll need is previous proposals or bids experience, as well as confidence in managing internal stakeholders and projects to strict deadlines, with an ability to “get up to speed” quickly. It would be great if you had some of the following skills, but don't worry if you don’t tick every box, we’ll help you develop along the way.

• Demonstrable experience in writing proposals in a professional services environment, with attention to detail
• Experience in running meetings with senior internal stakeholders, and excellent communication skills
• The ability to build business relationships quickly and effectively
• Advanced‑level knowledge of Microsoft PowerPoint and working knowledge of other Microsoft Office tools
• Strong ability to challenge thinking, share ideas and articulate reasoning
