Technical Project Manager

(aka the one who gets it built)

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

£55,000–£70,000

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. We’re here to fix that.

Our tech goes into real buildings – new builds and retrofits, residential and commercial. Mostly across the UK today, with growing demand internationally – including live opportunities in the Middle East, where you’ll likely run early proof-of-concept deployments before we build out local delivery teams. That means working with developers, main contractors, M&E consultants, building managers and end clients to turn signed contracts into deployed, working systems.

Now we need a Technical Project Manager to own that.

This is the person who makes deployments happen. You’ll plan them, run them, communicate them, fix them when they go sideways, and close them out properly. You’ll be the person who always knows where things stand when a developer asks, and the calm voice on the other end of the line when a contractor hits a snag at 4pm on a Friday.

We’re deliberately lean. That’s not code for chaotic. It means small team, high trust, high ownership and high output.

We also use AI tools heavily across the business. For this role specifically, we expect you to use AI to draft and refine RAMS, scopes of work, programmes, client updates, site reports and contractor comms – not because it sounds modern, but because it helps a strong PM move faster, communicate better, and stay on top of more work without dropping the ball. If you’re not already using tools like Claude or ChatGPT regularly to make your work faster and sharper, this probably isn’t the right fit.

This is a place for people who work hard, think clearly and use tools intelligently. Two out of three won’t cut it.

Deployment delivery – End-to-end project management for every Watergate installation: scoping, planning, scheduling, mobilisation, execution, commissioning and handover. New builds and retrofits, residential and commercial, UK and international.

Client and stakeholder management – You’re the face of Watergate to developers, main contractors, M&E consultants, building managers and end clients. Clear, calm, professional communication is non-negotiable.

Site coordination – Managing installers, subcontractors and site teams. Making sure people show up, do the right thing and leave the site properly. Site visits when they’re needed, not for the sake of it.

International proof-of-concepts – Running early deployments in new markets, starting with the Middle East, before we build out local delivery capacity.

Documentation and compliance – RAMS, scopes of work, programmes, O&M manuals, handover packs. Watergate’s deployment paperwork should be the kind contractors actually want to receive.

Risk and issue management – Spotting problems before they hit the critical path. Solving them early. Escalating only when you genuinely need to.

Process and playbooks – Building the deployment function as we scale. Templates, checklists and SOPs that make every project easier than the last.

Systems and delivery tools – Constantly looking for where AI can take grunt work off your plate: drafting RAMS, structuring SoWs, summarising site reports, generating client updates, prepping for meetings.

Internal projects where needed – Occasionally taking on important internal initiatives that need proper project management.

• 5+ years in project management, ideally delivering tech into buildings – smart building, AV, lighting controls, security, BMS, M&E, or similar
• PRINCE2, APM PMQ, PMP or equivalent – and the discipline that goes with it, not just the certificate
• Strong understanding of how construction and fit-out projects actually work: programmes, sequencing, snagging, handover
• Comfortable on a building site and in a boardroom in the same day
• Excellent written and verbal communication – clear, structured, and professional under pressure
• Genuinely AI-native – already using Claude, ChatGPT or similar tools regularly to do better work, faster
• Strong with Google Workspace, project management tools, and modern documentation practices
• Willing and able to travel internationally for early deployments – including stints in the Middle East
• Bonus if you’ve worked with smart water, leak detection, or sustainability tech specifically
• Bonus if you’ve delivered into both residential and commercial environments
• Bonus if you’ve run projects internationally, especially in the Middle East
• Hands-on, with no ego about the work
• Based in or able to work full-time from our London office
  

• Hate loose ends
• Believe a great RAMS is a competitive advantage, not a chore
• Can keep ten projects in your head and never drop one
• Stay calm when a contractor calls you with bad news
• Like building systems and templates that make the next project easier
• Can write a client email that ends a thread instead of starting three more
• Want to play a meaningful role in building a company, not just running someone else’s projects
  

• £55,000–£70,000 base salary, depending on experience
• Life and health insurance
• Whatever tools you need to do the job properly
• Professional development budget, including further PM qualifications if useful
• Real ownership of how Watergate gets deployed in the world
• Close partnership with the founder and the wider team
• Genuine room to grow, including building and leading a deployment team as we scale internationally. There may also be scope for equity as the role grows.
• A smart, ambitious team building something that matters
  

Full-time and based in our London office. We’re currently in NW2 and moving to Waterloo in summer 2026.

Expect regular travel to project sites across the UK, and meaningful international travel as we expand – starting with the Middle East, where we already have live demand. You may be the first Watergate person on the ground in a new market before we build out local teams.

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

1. Apply with your CV and a short cover note – tell us why this role, not just why you’re looking
2. Initial screening call – fit, motivation and practicalities
3. Take-home task – a realistic deployment scenario you’d actually face here. We respect your time and won’t ask for more than a few hours
4. Problem-solving interview – we’ll walk through your task and a live business scenario. We’re looking for structured thinking and clear judgement, not memorised frameworks
5. Informal final stage with the founder and a senior team member – relaxed setting, outside the office. The work questions are mostly answered by this point. This one is about whether we’d actually want to spend our days working together.
6. References and offer

If you’re the kind of PM who loves turning complex installs into clean handovers – and wants to do it with the best tools available, on a product that actually matters – we’d like to hear from you. Send your CV to careers@watergate.ai and tell us why this role fits you, and why you fit it.
