Job Description

Client proposals and contracts senior manager

In this role, you’ll play a pivotal part in Dot Dot Dot’s impact in London and beyond. Your primary responsibility will be to create the materials that help us win new contracts and partnerships. You’ll analyse the business and social value of each project, turning insights into persuasive cases for action. From there, you’ll craft compelling pitches and proposals, working closely with our senior leadership team to deliver them directly to clients and partners.

This is a collaborative, cross-cutting role at the heart of our business development work. You’ll help us respond to new enquiries, shape tailored proposals, and coordinate contracts - always ensuring our service stands out and reflects both our unique approach and the priorities of each client. Along the way, you’ll bring curiosity about what matters to clients, confidence with data, and the ability to coordinate people and processes to get things done.

You’ll be working closely with senior leaders, gaining cross-functional experience, and helping to shape how the role evolves over time. We’re an ambitious team with a social mission and a high bar for quality, and we’ll support you to learn as you go - through training, mentoring, and hands-on experience with friendly, knowledgeable colleagues across the business.

About you

We’re looking for someone who enjoys both the detail and the bigger picture - someone who takes pride in writing clearly and persuasively, and who can bring people and processes together to produce written outputs that truly resonate with clients.

You don’t need a background in sales or property; what matters most is a love of creating compelling, high-quality materials - whether that’s a persuasive pitch deck, a polished proposal, or a detailed report or contract.

If you’re motivated by translating ideas into action, spotting patterns, and helping good work shine, we’d love to hear from you.

You must have

• Excellent written communication - able to write clearly, persuasively and quickly, turning client conversations into compelling proposals and refining others’ content.
• Confidence with data - not necessarily a spreadsheet expert, but comfortable working with numbers, reviewing assumptions, and asking the right questions.
• Strong project coordination - experienced in bringing together people, information and deadlines to deliver pitches, proposals, or other complex work.
• Ability to prioritise and deliver - keeps work moving forward and meets competing deadlines without losing quality.
• Collaborative and client-facing - works well with colleagues across the business and represents Dot Dot Dot with professionalism and integrity.
• Curious and proactive - keen to learn, unafraid to ask questions, and willing to take initiative to fill gaps in knowledge.

You’ll have the opportunity to deepen your skills in:

• Using tools like Salesforce and financial models to track and assess opportunities.
• Understanding service design, legal risk, commercial assumptions, and client reporting
• Engaging senior leaders and external partners in strategic client conversations.
• Gaining hands-on experience with procurement, tendering, and contract negotiation.
• Public speaking - internally and externally
