The Opportunity
We are looking for a skilled Splunk Specialist to deliver end‑to‑end Splunk engagements, helping clients build and enhance their security monitoring capabilities. You will lead the full project lifecycle, from requirements gathering and stakeholder engagement through to data onboarding, alert development, and dashboard creation, ensuring solutions are aligned to both business and security objectives.

Work with the wider Splunk ecosystem, including tools like TrackMe, and contribute to automation and orchestration initiatives (including exposure to SOAR where applicable)
Leverage scripting languages such as Python and PowerShell to automate detection logic, enrich data, and integrate with security workflows
Provide mentorship and technical guidance to junior engineers, particularly on Splunk backend activities such as data ingestion, parsing, indexing, and troubleshooting
Collaborate closely with SOC analysts, incident responders, and global engineering teams to improve detection and response capabilities
Apply strong analytical and problem‑solving skills to translate threat intelligence into actionable detection use cases and continuously improve security operations

Demonstrable proficiency across a wide range of IT and cybersecurity technologies
Strong knowledge of key cybersecurity domains, including Identity and Access Management and Incident Management
High‑level analytical ability to solve unusual and complex problems
Ability to maintain up‑to‑date working knowledge of cybersecurity principles and best practices
