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. Each day might involve investigating alerts, analyzing logs, or network traffic using tools like Splunk. You will monitor security alarms, create detection content, use threat intelligence, and respond to breaches. Daily team meetings will review investigations and plan next steps. You’ll lead efforts to improve processes, mentor junior analysts, and support digital forensics and incident response. You’ll stay updated on cyber security tools and techniques, review past alerts, and prioritize incidents based on severity and impact.

About You

You should have a background in cyber security analysis and a passion for IT. Experience with host intrusion detection is preferred but training will be provided. You should understand Windows and Linux OS. 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 and network teams. Strong communication and problem-solving skills are essential.

Training and Development

We support your growth with internal and external training, opportunities across cyber security specialisms, and industry qualifications like SANS and CISSP. Opportunities to travel, attend conferences, and stay current with industry innovations are available but not mandatory.

Rewards and Benefits

Starting salary of £44,044 plus benefits: 25 days annual leave rising to 30 after 5 years, public holidays, performance recognition, interest-free season ticket loan, pension, cycle scheme, onsite facilities, parental leave, and more.

We value diversity and inclusion, encouraging applications from underrepresented groups including women, ethnic minorities, disabled persons, and those from low socio-economic backgrounds. Learn more at our diversity webpage.

Disability Confident

GCHQ is a Disability Confident Leader, committed to fair recruitment and support for disabled applicants. To secure an interview, candidates should meet minimum criteria including 6 months relevant experience and, optionally, management or delegation experience. Support and adjustments are available during recruitment.

What to Expect

Our process is fair and merit-based: application review, virtual interview, conditional offer. The process may take 6-9 months, so continue current employment until final offer.

Before You Apply

You must be a British citizen or dual national, and pass Developed Vetting (DV) security clearance. Review eligibility requirements, consider travel implications, and prepare a secure email.
