About the Role

We are looking for ahighly experienced IT Infrastructure & Support Engineer to join the Development Tools IT Team at Sony Interactive Entertainment.

This is a senior hands‑on internal IT role supporting approximately 120 users across Bristol and Dublin, most of whom are developers and highly technical staff. You will work as part of a small IT team responsible for local support, infrastructure operations, security remediation, monitoring and project delivery.

You will act as a key senior technical person within the team. You will take ownership of complex support issues, support and administer local infrastructure, help improve patching and vulnerability remediation, contribute to infrastructure projects, and provide guidance to less senior team members where appropriate.

This is not a narrowly defined project‑only role. Because we are a small team, everyone gets involved where needed. While there is significant exposure to infrastructure and project work, you should also be comfortable helping with user‑facing support and advanced desktop issues.

• Troubleshooting issues involving DNS, DHCP, VLANs, routing, switching, VPNs and firewalls.
• Supporting a Juniper switching and Palo Alto firewall environment.
• Working with global SIE teams where services are centrally managed.
• Supporting vulnerability remediation and patching using tools such as KACE, Qualys and Domo.
• Investigating patch failures and working with users to resolve remediation issues.
• Supporting endpoint security processes involving tools such as Crowd Strike.
• Monitoring systems and alerts using Zabbix.
• Helping shape and improve IT alerting processes.
• Supporting backup and recovery processes using Commvault.
• Creating and maintaining documentation, troubleshooting guides and runbooks in Confluence.
• Working alongside wider internal IT functions.
• Helping guide and support the Desktop Support Engineer where appropriate.
• Helping reduce IT friction for a highly technical developer user base.

What We’re Looking For

We are looking for someone with strong technical support and infrastructure experience, excellent troubleshooting ability, and the confidence to act as a senior technical person within a small IT team.

• Proven experience in a senior 2nd line, 3rd line, infrastructure support, systems support or similar role.
• Experience collaborating with wider support and technical teams.
