• Work with the maintenance team on site walk-throughs, risk assessments and permit-to-work processes
• Liaise with internal teams and contractors to ensure safe, compliant, and high-quality outcomes
• Act as first responder to any issues affecting critical systems, helping to resolve and learn from incidents
• Support planned and reactive maintenance schedules with documentation and continuous improvement in mind

What we’re looking for:

• A qualified engineer with at least 4 years’ post-certification experience in mechanical/HVAC environments
• Confident working independently or as part of a team in a high-integrity environment
• Someone who brings a proactive, problem-solving mindset and a desire to grow their expertise
• Strong communication skills and experience in customer-focused or regulated settings

Essential qualifications and experience:

• HND in Mechanical Engineering or equivalent
• F-Gas Cat 1 (City & Guilds)
• Professional certification such as NCC or REC (or national equivalent)
• Legionella awareness
• Experience maintaining HVAC systems in complex or critical environments (data centre experience a plus)

What we offer:

• The opportunity to join a growing, forward-thinking company at the cutting edge of digital infrastructure
• A supportive environment that values safety, inclusion, and professional development
• Structured progression and access to ongoing training and mentoring

At Pure DC, we value difference and welcome applications from candidates of all backgrounds and identities. We’re committed to building a team that reflects the diversity of the communities we serve – and to creating an environment where everyone can thrive.
