• Design, develop and refine automated incident response playbooks and Security Orchestration, Automation and Response (SOAR) workflows.
• Monitor, baseline and audit log ingestion pipelines to maintain telemetry health, identify gaps and ensure consistent security visibility.
• Build and manage API integrations and telemetry connectors across Ramsay’s security technology stack.
• Operationalise threat intelligence to support proactive threat hunting and the development of autonomous, agentic SOC workflows.
• Act as the technical quality assurance lead for our Managed Security Service Provider (MSSP), validating escalations, assessing detection effectiveness and driving continuous improvement.
• Lead root cause analysis, threat modelling and post-incident engineering improvements to strengthen detection and response capabilities.
• Collaborate with internal technology teams and external security partners to improve the integration and effectiveness of security platforms.
• What You’ll Bring

You are a highly technical cybersecurity professional with extensive experience in enterprise security operations, detection engineering and security automation.

You bring a hands‑on approach to solving complex technical challenges, a strong understanding of evolving cyber threats and the ability to translate security intelligence into effective detection and response capabilities.

You will bring

• Extensive cybersecurity experience within a large enterprise environment.
• Strong hands‑on experience across detection engineering, SIEM, EDR and SOAR platforms.
• Demonstrated experience designing, tuning and maintaining detection rules and security use cases.
• Experience developing automated incident response workflows and integrating security technologies through APIs.
• Strong technical knowledge of data parsing, log ingestion, telemetry pipelines and security monitoring.
• A sound understanding of the cyber threat landscape, adversary tactics, techniques and procedures (TTPs), and frameworks such as MITRE ATT&CK.
• Experience working with MSSPs, Managed Service Providers (MSPs) and hybrid SOC operating models.
• Strong analytical and problem‑solving skills, with the ability to investigate complex incidents and drive technical improvements.

Desirable but not essential

• A degree in Cybersecurity, Information Technology or a related discipline.
• Experience working within healthcare, critical infrastructure or another highly regulated environment.
