London
Senior Business Development Manager (aka the one who turns interest into revenue) Full-time, on-site â London with UK and international travel ÂŁ60,000âÂŁ80,000 base + uncapped commission; OTE ~ÂŁ130,000 Watergate helps buildings detect leaks, cut water waste, and reduce the carbon footprint of every litre, proving the impact with data. Weâre building the missing circuit breaker for water. Every building has fire protection. Every building has security. Almost none have proper water protection, despite leaks causing huge financial and operational damage. Weâre here to fix that. The market is wide open. Asset managers, developers, M&E specifiers, contractors, FM providers, distributors, resellers and insurers â across the UK and increasingly internationally â all have a real reason to care about what we do. We need someone to turn that demand into deals. Now we need a Senior Business Development Manager. This is the person who owns the sales process end to end: picking up qualified inbound, running discovery, building relationships with specifiers and asset managers, navigating large-account sales cycles, and closing. Youâll work directly with the founder and our Commercial Director on GTM strategy, and youâll be the one carrying the number. Weâre deliberately lean. Thatâs not code for chaotic. It means small team, high trust, high ownership and high output. We use AI tools heavily across the business, including how we generate and qualify pipeline. Youâll be expected to benefit from that and help shape it: telling us whatâs working, what isnât, and where to push next. Day to day, youâll use AI to research accounts, draft proposals, prep for meetings, summarise calls, refine outreach, and remove the admin friction that slows most sales teams down. If youâre not already using tools like Claude or ChatGPT regularly to do better work, faster, this probably isnât the right fit. This is a place for people who work hard, think clearly and use tools intelligently. Two out of three wonât cut it. If youâre the kind of seller who builds real pipeline and closes complex deals, keep reading. What youâll own End-to-end sales â Qualification, discovery, demos, commercial negotiation, contracting and close. You own the number and the process. Specifier and asset manager relationships â Building real, durable relationships with the people who decide what goes into buildings: asset managers, M&E consultants, contractors and developers. Youâll work directly with the Commercial Director on mapping and executing our specifier-led GTM strategy. Large-account sales â Multi-stakeholder deals, long cycles, real procurement, real contracts. You know how to navigate them and bring them home. Inbound conversion â Taking calls and enquiries from prospects, distributors, resellers and insurers, in the UK and internationally, and turning interest into qualified pipeline. The CRM and sales stack â HubSpot, LinkedIn Sales Navigator, Clay and whatever else helps you sell. Youâre disciplined with your data because you understand that a clean pipeline is a closing pipeline. If a deal isnât in the CRM, it doesnât exist. AI-enabled selling â Using AI to research accounts, prep for meetings, draft outreach, summarise calls, and shape proposals. Helping us improve the AI-driven inbound engine by feeding back whatâs working and what isnât. Marketing and content as commercial tools â Youâll have full access to marketing, design, video, PR, white papers and content. Youâll be expected to direct that support clearly and use it well. New verticals â Weâre focused on PBSA and BTR right now, but the opportunity is much bigger: new build, commercial, FM, hospitality, healthcare, education, data centres, public and more. Youâll help us prioritise and crack the next vertical.
