Code Wizards Group is a world leader in backend and multiplayer infrastructure for the gaming industry. From high-scale AAA console and PC games to fast-paced mobile indie titles, we empower studios to bring multiplayer experiences to life.

We are looking for an organised, proactive IT Systems and Compliance Administrator to help maintain our internal IT infrastructure and support our information security and compliance activities.

You’ll also coordinate day-to-day ISO 27001 compliance activities, maintain evidence and documentation, support audits and help complete security assessments from clients and partners.

The role is primarily focused on internal systems and compliance, although you may occasionally support technical or security activities across the wider Code Wizards Group.

• Work with internal stakeholders to verify responses and gather evidence.

• Maintain a library of approved security responses and supporting documentation.

• Track deadlines, follow-up questions and resulting actions.

• Escalate gaps, unclear requirements or significant commitments for review.

Essential experience and skills

• Experience working in systems administration or an infrastructure-focused IT role.

• Experience with on-premises servers and virtualised environments.

Support and development

You’ll work closely with the Head of IT and have the opportunity to develop your experience across infrastructure, cloud technologies, information security and ISO 27001 compliance.
