This is a hands-on engineering role, working with state-of-the-art mechanical and HVAC systems in a fast-paced, safety-first environment. You’ll play a key role in keeping our systems running efficiently, safely and reliably – and you’ll be empowered to share ideas, solve problems and take ownership of your impact.

What you’ll be doing:

  • Maintain and troubleshoot HVAC, mechanical and plant systems including chillers, boilers, compressed air systems, pumps and steam equipment
  • Use BMS, CMS and other systems to monitor, optimise and log system performance
  • 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.
