About Our Outside IR35 Splunk Contract Roles
What does a splunk contractor do?
Splunk contractors are engaged to implement, develop, and optimise the Splunk platform for security information management, IT operations monitoring, and log analytics use cases. Splunk's two primary use cases in the UK enterprise market are SIEM and security analytics within security operations centres, and IT operations and infrastructure monitoring within technology operations teams. Contract engagements involve implementing Splunk Enterprise or Splunk Cloud, developing custom searches and dashboards, building Splunk Enterprise Security correlation searches and notable event management, creating Splunk SOAR playbooks for automated response, managing data onboarding and indexer configuration, and optimising Splunk deployments for performance and licensing cost.
Splunk contractors are expected to have deep, hands-on expertise with the Splunk platform and strong proficiency in SPL (Splunk Processing Language), the query language used for all Splunk search, analysis, and dashboard development. For security-focused roles, experience configuring and tuning Splunk Enterprise Security, developing correlation searches that detect meaningful threat patterns while managing false positive volumes, and building risk-based alerting workflows is the primary technical requirement. For IT operations roles, experience building Splunk dashboards and alerts for infrastructure monitoring, application performance management, and operational intelligence is expected. Knowledge of Splunk architecture components including indexers, search heads, forwarders, and the Splunk Deployment Server for managing distributed environments is expected for roles with platform administration responsibility. Splunk certifications, particularly Splunk Core Certified Power User and the ES and SOAR certifications, are well regarded.
What is the market like for splunk contractors?
The Splunk contract market is a specialist and active segment within the cybersecurity and IT operations contractor market. Splunk has very deep penetration in the financial services sector, where it has been the dominant SIEM platform for many large banks and insurers, creating a consistent market for Splunk contractors in security operations and compliance use cases. While Microsoft Sentinel is growing rapidly and taking market share for new SIEM implementations, the large installed base of Splunk across existing enterprise customers will generate contractor demand for management, optimisation, and development work for many years. IT operations and observability use cases provide an additional and growing source of Splunk contract demand beyond the security market. Compensation reflects the specialist SPL expertise and platform depth required.
What does Outside IR35 mean?
IR35 is UK tax legislation that determines whether a contractor is genuinely self-employed or working in a manner that resembles employment. When a contract is classified as outside IR35, the engagement is treated as a business-to-business arrangement. The contractor operates through their own limited company, invoices for services, and manages their own tax affairs including corporation tax, self-assessment, and VAT where applicable.
Outside IR35 engagements are assessed against three key factors: the degree of control the client exercises over how the work is delivered, whether the contractor has a genuine right to provide a substitute, and whether there is a mutuality of obligation between the parties. Contracts that demonstrate contractor autonomy, project-based delivery, and the absence of ongoing employment obligations are more likely to sit outside IR35. Since April 2021, responsibility for making this determination sits with the end client for medium and large private sector organisations.
On QualityContracts.co.uk, approximately 28% of roles with a stated IR35 status are classified as outside IR35. The proportion varies by sector and role type, with some disciplines seeing a significantly higher or lower share of outside IR35 opportunities. Each listing on this page displays its IR35 status where provided by the hiring organisation.
What splunk roles are usually Outside IR35?
Splunk contracts can sit outside IR35 when structured around implementation projects: deploying Splunk Enterprise or Splunk Cloud, building dashboards and alerts for specific use cases, or migrating from a legacy log management tool. The implementation has defined phases and a go-live milestone. Security consultancies and organisations building new observability or security monitoring capabilities commission most outside IR35 Splunk work. Splunk certifications are a significant differentiator in this niche market.
How much do splunk contractors usually earn when working Outside IR35?
