Job description

About The Role

Site Administrator - Parc Adfer, Deeside

Be at the heart of a facility that powers progress.

Are you an organised, people-focused problem-solver who thrives in a fast-paced environment? Do you want your work to help shape a cleaner, greener future? Then this might be the role for you.

At enfinium, we’re leading the way in energy-from-waste. Our facilities transform waste into sustainable power for the UK – and we’re proud to play a vital role in helping society reduce landfill and carbon emissions.

We’re looking for an enthusiastic Site Administrator to join our team. You’ll provide essential administrative support to our Plant Management and senior teams, acting as a vital link between operations, people, and performance. No two days are the same, and you’ll be involved in everything from document management and onboarding new starters to supporting health, safety, and compliance reporting, site tours, and stakeholder engagement.

What you’ll be doing:

• Keeping things running smoothly with day-to-day admin support for our Plant Manager, SHEQ, Operations, Maintenance, HR, Procurement, and Communications teams.
• Supporting the full employee lifecycle – including recruitment, onboarding, training logistics, and accurate record-keeping.
• Helping ensure compliance with company systems, health & safety procedures, and ISO standards (ISO 9001, 14001, 45001).
• Managing site documentation, reporting deadlines, training records, and audit support.
• Coordinating meetings, preparing agendas, and taking minutes for the senior team.
• Welcoming visitors, supporting site tours, and liaising with local authorities – you’ll be a friendly and professional ambassador for enfinium.

What you’ll bring:

• Experience working in a busy office environment – ideally within an operational or technical setting.
• Excellent organisational skills and the ability to juggle multiple tasks with accuracy and calm.
• Confident IT skills (especially Microsoft Office – Excel, Word, PowerPoint).
• Strong communication skills – written and verbal – and the ability to work with people at all levels.
• Familiarity with ISO standards and a basic understanding of HR or compliance processes would be a bonus.

You’ll love this job if you:

• Enjoy variety – one day you’re collating reports for regulators, the next you’re setting up a site tour for a local school.
• Get satisfaction from helping others work more efficiently.
• Are curious, proactive, and always willing to roll up your sleeves to help the team.
