Job description

About the company

At Kingsley Healthcare, we are more than just a care home group - we are a proud, family-run business driven by a passion to make a meaningful difference in people’s lives every single day. Our dedicated teams transform care into a calling, delivering excellence with compassion, integrity, and respect.

As the UK’s only large care home provider to achieve B Corp certification, we continue to lead the sector in responsible, values-driven care. In 2024, we were honoured to be named Health Investor’s Residential Elderly Large Care Provider of the Year, a testament to our commitment to quality and innovation.

For eight consecutive years, we’ve been recognised among the Top 20 Large UK Care Home Groups by carehome.co.uk, reflecting consistently high standards and resident satisfaction. We are also proud to be a Real Living Wage employer, ensuring that the dedication of our team members is valued and fairly rewarded.

Our commitment to people-first values has earned us outstanding workplace recognition, including a 4.7 rating on Glassdoor, a 4.5 rating on Indeed, and the No.1 ranking in the UK for wellbeing at work (Indeed’s Better Work Awards 2023).

If you're passionate about delivering exceptional care and want to be part of a forward-thinking organisation that puts both its residents and people at the heart of everything it does, we’d love to hear from you.

About the role

We’re on the hunt for a tech-savvy, proactive problem-solver with a passion for IT infrastructure, systems management and cybersecurity to join our dynamic team. You’ll have hands-on experience with Microsoft environments, including managing Active Directory, Exchange Server (on-premises and cloud), and Office 365. Your skills in PowerShell scripting, troubleshooting and securing enterprise systems will make you an invaluable member of our IT team.

We’re particularly keen on candidates with experience in Azure AD, Office 365 and hybrid setups. A strong understanding of cybersecurity tools and practices, Windows domain environments, networking concepts and experience in help desk ticketing and troubleshooting will help you thrive in this role.

While not essential, experience with Mimecast, LogMeIn Central, Duo MFA, and managing Linux servers would set you apart. If you’re familiar with SQL databases, web servers (like cPanel), scripting languages like Python and EDR/XDR platforms such as ESET, you’ll have an edge. Above all, we value someone eager to learn, adapt and grow with us as we migrate to Office 365 and strengthen our security posture.
