We’re looking for an IT Security Engineer to join our Security Operations team. You’ll help protect the systems, services and information that support the National Trust and the millions of people who engage with us every year. Working alongside experienced security professionals, you’ll play a key role in maintaining the confidentiality, integrity and availability of our digital services, helping to identify and respond to security threats, investigate incidents and strengthen our overall security posture. This is an excellent opportunity for someone who enjoys problem‑solving, continuous learning and working in a collaborative environment where their expertise can make a meaningful impact.
What it’s like to work here
You’ll be joining a collaborative and supportive Technology team based at Heelis, the National Trust’s award‑winning central office in Swindon. Home to around 500 colleagues from across the organisation, Heelis is a unique and sustainable workplace, designed using materials sourced from National Trust land and recognised nationally for its environmental credentials. Within Security Operations, you’ll work closely with Information Security, Infrastructure, Networks, Service Management and specialist technology partners, helping to protect critical services and support the delivery of secure, resilient technology across the Trust. Whether you’re investigating incidents, implementing new security solutions or contributing to continuous improvement initiatives, you’ll be encouraged to share ideas, build your expertise and develop your career in an environment that values collaboration and learning.
Your contractual location will be our head office in Swindon and there will be an expectation for you to attend the office. However, there is flexibility on where you are based at other times. You will be required to work at a National Trust location for 40‑60% of your working week. This will be discussed in more detail at interview.
What you’ll be doing
You’ll help ensure the National Trust operates in a safe and secure way by monitoring security systems, investigating alerts and responding to security incidents. Working with colleagues across Technology, Information Security and strategic suppliers, you’ll identify and communicate risks, support remediation activities and help maintain effective security controls and standards.
You’ll play a key part in investigating security incidents escalated through our Security Operations processes, analysing activity within our SIEM platform and using security data from across the technology estate to identify unusual behaviour and potential threats. You’ll also contribute to technical design and implementation activities, supporting the delivery of approved security solutions into operational environments. Alongside day‑to‑day operational responsibilities, you’ll support continuous improvement initiatives, assist with security reporting and share knowledge with colleagues to strengthen capability across the wider team.
