We are seeking an Infosec Analyst to serve as the primary operational interface into Era4's Security Operations Center (SOC). This role focuses on security monitoring, threat detection, incident response, and protecting our next-generation AI datacentre infrastructure, cloud platforms, and applications through proactive security operations.
You will be the key point of contact between security monitoring systems and engineering/operations teams, responsible for monitoring our datacentre security estate, identifying threats across network infrastructure and Era4's proprietary cloud platform, coordinating incident response, managing alerts, and continuously improving our security posture.
The successful candidate combines strong technical security knowledge with hands-on experience analysing logs from enterprise firewalls, datacentre networking, and proprietary infrastructure platforms, along with excellent communication skills and the ability to triage and escalate issues effectively.
Key Responsibilities
Security Monitoring & Alert Management

- Analyse firewall logs (Palo Alto, OpnSense), network traffic, system events, and GPU infrastructure telemetry to identify root causes and attack patterns.
- Conduct threat hunting activities to proactively identify indicators of compromise in datacentre traffic and network flows.
