Day to day, the Senior Security Analyst will be responsible for identifying, prioritising, and reducing organisational cyber risk through proactive exposure management, investigating alerts and responding to incidents. The role will be maintaining and optimising Cyber Security tooling as well as contributing towards the increased use of automation and AI. The role’s analytical and risk skills will be applied across the whole Cyber Security team to ensure vulnerabilities and exposures are identified, prioritized by risk, and remediated efficiently and to assist with security improvements and risk management activities.

This role suits someone with broad cyber security experience who is looking to deepen their expertise and make a measurable impact in an exciting, fast-moving industry.

Work closely with system owners to help them manage their vulnerabilities. Assist them in implementing any resolution actions in a risk focused and timely manner.
Support the Security Risk Management function with risk analysis activities, including third party risk assessments.
Design and implement automation‑supported workflows and explore the practical use of AI‑assisted features within security tools to improve efficiency and consistency.
Maintain and enhance our tools and platforms to continuously improve our intelligence, detection and response capability.
Perform in-depth investigation and analysis of security alerts to identify and promptly respond to security events.
Collaborate with key stakeholders during investigations to gather further information and coordinate response actions.
Derive value from relevant threat intelligence to drive proactive action.
Influence the strategic direction of our team by presenting insight into the security events, alerts and incidents we handle.
Maintain a broad understanding of IT/online environments and key company assets to enhance decision making and response to incidents.
Support the detection of game specific abuses such as leaks, cheats, piracy, copyright abuse, player account compromise and rogue sites.

Interpersonal and Technical Skills

Effective communication skills with non-technical stakeholders and executives.
Able to stay focused during incidents and work methodically with the support of the wider team.
Curious about how automation and AI‑assisted capabilities can support Cyber Security work and improve ways of working.
Comfortable prioritising work, making sound risk-based recommendations, and knowing when to seek input or escalate.
Familiarisation with common Incident Response frameworks such as NIST.
Strong appreciation of attacker tactics, techniques and procedures.
Occasional flexibility may be needed for urgent incidents; we aim to plan work sustainably.
