Job Description

Senior Cyber Security Analyst

Cheltenham

£44,044 (includes £2,658 non-concessionary payment)

Flexible working: We recognise the importance of a healthy work-life balance and offer full-time, part-time, and compressed hours. While hybrid working can be more restricted, due to the nature of the work, around 40% home working may be available depending on business needs.

About Us

GCHQ is an intelligence, cyber and security agency with a mission to keep the UK safe. We use cutting-edge technology, ingenuity and partnerships to identify, analyse and disrupt threats. Working with our intelligence partners MI5 and MI6, we protect the UK from terrorism, cyber-attacks and espionage. At GCHQ you’ll do varied and fascinating work in a supportive and inclusive environment that puts the emphasis on teamwork.

The Role

As a Senior Cyber Security Analyst, you’ll be key to protecting our organisation against a range of cyber threats. From malware outbreaks and insider activity to denial-of-service attacks and phishing, your role will be vital in detecting, responding to, and mitigating risks. You might investigate high-priority alerts, analyse logs or network traffic, and endpoint activity using tools like Splunk. Your daily tasks include monitoring security alarms, creating detection content, using threat intelligence, and responding to breaches. Each day begins with a team meeting to review investigations and plan.

Continuous improvement is central to all we do. You’ll lead efforts to streamline processes, mentor junior analysts, and provide expert guidance. You’ll have opportunities to explore Digital Forensics and support security incidents, contributing to the team’s future direction and staying updated with the latest cybersecurity tools and techniques.

About You

You should have a background in cyber security analysis and a passion for IT. Experience with host intrusion detection analysis is ideal but training will be provided. You should understand both Windows and Linux Operating Systems. A minimum of 6 months experience as a Cyber Security or SOC Analyst is required. You should be comfortable working independently and collaboratively, working closely with IT teams and network administrators. Effective communication and problem-solving skills are essential.

Training and Development

We support your growth through internal and external training, helping you refine skills and expand your expertise. You’ll have the opportunity to work across various cybersecurity specialisms and pursue industry-recognized qualifications like SANS and CISSP. Opportunities for travel, conferences, and staying current with cybersecurity innovations are available but not mandatory.

Rewards and Benefits

You’ll receive a starting salary of £44,044 plus benefits including 25 days of annual leave (rising to 30 after 5 years), public holidays, performance recognition, interest-free season ticket loan, pension scheme, cycle to work scheme, on-site facilities, and paid parental leave.

We value diversity and inclusion, reflecting society in our workforce. We welcome applications from underrepresented groups, including women, ethnic minorities, disabled individuals, and those from low socio-economic backgrounds. Find out more on our website: Diversity and Inclusion.

We’re Disability Confident

• Line management or delegation experience
