Head of Training and Business Development in London

Full-time, on-site – London with UK and international travel.

Watergate helps buildings detect leaks, cut water waste, and reduce the carbon footprint of every litre, proving the impact with data. We’re 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. Asset managers, developers, M&E specifiers, contractors, FM providers, distributors, resellers and insurers – across the UK and increasingly internationally – all have a real reason to care about what we do.

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. You’ll work directly with the founder and our Commercial Director on GTM strategy, and you’ll be the one carrying the number.

We use AI tools heavily across the business, including how we generate and qualify pipeline. You’ll be expected to benefit from that and help shape it: telling us what’s working, what isn’t, and where to push next. Day to day, you’ll 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.

• End-to-end sales – Qualification, discovery, demos, commercial negotiation, contracting and close.
• Specifier and asset manager relationships – Building real, durable relationships with the people who decide what goes into buildings: asset managers, M&E consultants, contractors and developers. You’ll work directly with the Commercial Director on mapping and executing our specifier-led GTM strategy.
• Large-account sales – Multi-stakeholder deals, long cycles, real procurement, real contracts.
• The CRM and sales stack – HubSpot, LinkedIn Sales Navigator, Clay and whatever else helps you sell. You’re disciplined with your data because you understand that a clean pipeline is a closing pipeline. If a deal isn’t in the CRM, it doesn’t exist.
• AI-enabled selling – 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 what’s working and what isn’t.
• Marketing and content as commercial tools – You’ll have full access to marketing, design, video, PR, white papers and content.
• New verticals – We’re 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. You’ll help us prioritise and crack the next vertical.

5+ years in B2B sales or business development, with a track record of closing large, complex accounts.

• Real experience selling into asset managers and/or M&E specifiers and contractors – this is core to the role.
• Familiar with, but also know how to shorten long sales cycles, multi-stakeholder deals and real procurement.
• Disciplined CRM operator – ideally HubSpot, with proper hygiene around pipeline, forecasting and notes.
• Fluent with LinkedIn Sales Navigator, Clay and other modern sales tools.
• Excellent written and verbal communicator with strong commercial instincts.
• Bonus if you’ve sold smart building, water, energy or sustainability tech.
• Bonus if you’ve sold into PBSA or BTR.
• Bonus if you’ve sold internationally, especially in the Middle East.
• Based in or able to work full-time from our London office.

Full-time and based in our London office. We’re currently in NW2 and moving to Waterloo in summer 2026. Expect regular travel to client meetings and sites across the UK, plus international travel as we expand, including to the Middle East, where we already have live demand.

We move fast and we don’t waste your time.

# Take-home task – a realistic commercial scenario you’d actually face here. Problem-solving interview – we’ll walk through your task and a live business scenario. Informal final stage with the founder and a senior team member – relaxed setting, outside the office. If you’re the kind of seller who loves the long game of large-account sales, and wants to do it on a product that actually matters, we’d like to hear from you.
