About Linnaeus

Linnaeus is a forward-thinking partnership of highly respected primary care and referral veterinary practices across the UK and Ireland. We bring together some of the best clinicians in the profession, united by two key principles: a commitment to excellence and a passion to make A BETTER WORLD FOR PETS.

We carefully select the practices we partner with to ensure the highest standards of patient care. Together, we form a growing community of like-minded veterinary professionals across all fields of veterinary medicine, including small animal, farm, and equine.

Our work is guided by our Five Principles, which shape every decision we make:

  • Commitment to quality of work and contribution to society
  • Responsibility to act now
  • Mutuality of benefit for all stakeholders
  • Efficiency in the use of resources
  • Financial freedom to make independent decisions

The Role

We are looking for an experienced Senior IT Infrastructure Engineer to join our Infrastructure Team on a 9-month fixed term contract, working 2 days per week, based primarily from our Shirley office and the rest of the time from home.

This is an exciting opportunity to play a key role in supporting and maturing Linnaeus’ IT infrastructure estate. You will balance business-as-usual support with project-based work, helping to standardise and future-proof a diverse and evolving IT environment following continued growth and acquisitions.

Working closely with the Infrastructure Team Manager, Principal Infrastructure Engineer, and wider IT stakeholders, you will act as a senior escalation point and contribute to the delivery of stable, secure, and high-performing infrastructure services across the Group.

Key Responsibilities

  • Act as an escalation point for complex infrastructure incidents and issues
  • Maintain, monitor, and proactively improve infrastructure availability and performance
  • Plan and deliver infrastructure maintenance, upgrades, and improvement projects
  • Support the transformation of a varied IT estate into a standardised, best-in-class platform
  • Contribute technical advice and proposals to strategic IT and business planning
  • Deliver infrastructure services aligned to ITIL best practice and project delivery aligned to PRINCE2 (or equivalent)
  • Provide clear, concise communication to technical and non-technical stakeholders
  • Support, coach, and mentor other engineers within the team

The role will occasionally require evening or weekend work to minimise disruption to practices. Overtime and expenses will be paid in line with company policy. Due to the nature of acquisitions, project work may sometimes be unpredictable.
