Senior Cyber Security Analyst

Location: Cheltenham

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

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.

As a Senior Cyber Security Analyst, you’ll be key to protecting our organisation against a range of cyber threats. Your responsibilities include detecting, responding to, and mitigating risks from malware outbreaks, insider activity, denial-of-service attacks, and phishing. Daily tasks may involve investigating high-priority alerts, analysing logs, or network traffic using tools like Splunk. You will monitor security alarms, create detection content, use threat intelligence, and respond to breaches. Each day begins with a team meeting to review investigations and plan.

Continuous improvement is central to our work. You’ll lead efforts to streamline processes, mentor junior analysts, and provide expert guidance. Opportunities to explore Digital Forensics and support security incidents are also available. You will contribute to shaping the team’s future, stay updated with the latest cybersecurity tools and techniques, and review past alerts to prioritize incidents based on severity and impact.

You should have a background in cyber security analysis and a passion for IT. Experience with host intrusion detection analysis is preferred but training will be provided. A solid understanding of Windows and Linux OS is required. You need at least 6 months experience as a Cyber Security or SOC Analyst. As a leader, you should be comfortable working independently and collaboratively, working closely with IT teams and network administrators. Effective communication and problem-solving skills are essential.

We support your growth from day one through internal and external training. You’ll have opportunities to work across various cybersecurity specialisms, pursue industry-recognized qualifications like SANS and CISSP, and attend conferences. Travel opportunities are infrequent and not mandatory.

You’ll receive a starting salary of £44,044 plus benefits including:

• 25 days annual leave, rising to 30 days after 5 years, plus 10.5 days public holidays
• Employee recognition schemes
• Interest-free season ticket loan
