We are seeking a Senior Technical Support Engineer to provide expert support for Cortex XSIAM-focused services within a security-sensitive environment. This role will suit an experienced security professional who can investigate complex technical issues, guide customers and internal teams, and help maintain resilient, high-performing security operations.

You will act as a senior escalation point for incidents involving endpoint protection, detection and response, log collection, analytics, integrations and security operations workflows. Responsibilities will include diagnosing advanced product and platform issues, analysing logs and system behaviour, reproducing faults, developing practical workarounds, and coordinating resolutions through to completion. You will also contribute to service improvement by identifying recurring problems, documenting solutions and sharing technical knowledge.

The role will involve working closely with engineering, product, consulting and customer-facing teams. You will support onboarding and configuration activities, advise on best practice, assist with investigations and provide clear technical communication to both technical and non-technical stakeholders. You may also contribute to knowledge-base articles, operational procedures, training materials and customer reviews.

Strong knowledge of operating systems, networking, authentication, scripting and log analysis is expected. Experience with incident response, threat detection, APIs, cloud platforms and troubleshooting distributed environments would be advantageous.

You will need excellent analytical and problem-solving skills, a structured approach to prioritisation and the ability to manage multiple complex cases in a fast-paced environment. Strong written and verbal communication is essential, along with a collaborative, customer-focused attitude and the confidence to take ownership of escalated issues.

This position requires the successful applicant to hold, or be eligible to obtain and maintain, the necessary UK security clearance. Candidates must be willing to comply with relevant screening, security and operational requirements.
