• Engineering secure log ingestion pipelines across hybrid cloud and on prem environments
• Supporting onboarding of new clients into the SOC to ensure correct configuration and data flow
• Contributing to threat hunting and detection engineering initiatives
• Maintaining documentation, diagrams and configuration standards
• Mentoring junior engineers and analysts and sharing best practice

What You’ll Bring

• 3 to 5 years of experience in a SOC, security engineering or cyber operations environment
• Hands on experience with SIEM or EDR platforms such as Microsoft Sentinel, Splunk, Defender, CrowdStrike or Elastic
• Proven ability to build and tune detection rules, dashboards and automation playbooks
• Knowledge of scripting or automation using KQL, PowerShell, Python or similar
• Familiarity with log management, APIs and data normalisation
• Understanding of cloud security across Azure, AWS and M365

• Knowledge of MITRE ATT&CK mapping and detection engineering frameworks
• Experience using Infrastructure as Code such as Terraform, Bicep or ARM templates
• Integration experience with ServiceNow or ITSM tools
• Exposure to threat hunting, vulnerability management or red team automation

What You’ll Get
