Era4 develops, owns and operates AI infrastructure across the UK, powered by renewable energy. Converting legacy industrial and energy sites into modern data-centre facilities, Era4 is combining brownfield regeneration opportunities with cleaner, efficient, scalable compute capacity for healthcare, research, finance, enterprise, and public-sector organisations.
We are seeking a Technical Project Manager to join our fast-scaling team. In this role, you will deliver projects across our technology and infrastructure teams as we grow from one site to several. You will work with engineers to turn technical plans into clear delivery plans, keep several connected work streams moving, and support the PMO by keeping our projects in one clear view. This is an opportunity to join a mission-led AI business redefining infrastructure, intelligence, and impact for enterprise customers.
Key Responsibilities:
Delivery:
- Run technology projects across infrastructure, network, systems and internal tools.
- Work with engineers to translate technical designs into plans with clear steps, owners, dates and dependencies.
- Keep several connected workstreams moving in parallel, and understand how a delay in one affects the others.
- Roll out changes in stages, with a test group first, a rollback plan if needed, and support after go-live.
- Clear blockers and drive issues to resolution, rather than simply passing them on.
- Hold suppliers and contractors to their commitments.
PMO support:
- Keep plans, the risk log, actions, and the decision log up to date and consistent across projects.
- Help maintain a clear view of all projects: what’s being done now and what’s on hold, and why.
- Prepare updates for the weekly PM session.
- Spot recurring problems and help fix the root cause, whether that’s a process, a tool, or how teams hand work over.
Working with people:
- Be the main point of contact between the technology teams, operations, suppliers and the PMO.
- Explain technical details clearly to non-technical people.
- Distinguish real progress from activity, and flag slipping dates early.
Essential Experience:
- Junior to mid-level project or PMO experience in IT, technology or infrastructure.
- Sufficient technical understanding to ask engineers good questions, not just track their tasks.
- Proven ability to run multiple projects across several teams, managing dependencies simultaneously.
- Confident working with suppliers and contractors to support successful project delivery.
- Skilled in maintaining project documentation, including project plans, risk logs and action lists.
One or more would be an advantage:
- Experience in a fast-growing technology, cloud, infrastructure or AI company.
- Some understanding of data centre basics: power, cooling and networking.
- Experience using data, automation or AI to reduce manual status chasing.
- Agile, Waterfall or a mix of both. GPU experience is not required.
Why Join Era4:
You’ll be joining a mission-driven start-up building critical national infrastructure, where operational excellence directly enables growth. This role offers high visibility with leadership, real autonomy, and the chance to shape how a next-generation company operates at scale.
Diversity & Inclusion:
Era4 is an equal opportunity employer. We celebrate diversity and are committed to creating an inclusive environment for all employees.
