Connect to your opportunity

As a Cybersecurity Controls Testing Analyst, you will support DT's Controls Assurance Testing Programme by validating the design and operating effectiveness of security controls through a combination of automated and manual testing. Working closely with the Cyber Compliance Manager and technical stakeholders, you will help translate regulatory, policy, and industry-standard requirements into measurable controls, identify opportunities to automate testing through data and system integrations, and perform evidence-based assessments where automation is not feasible. You will also support the validation of remediation activities, helping drive control deficiencies through to closure and contributing to reporting and governance activities.

The ideal candidate will bring a combination of technical cyber security experience and GRC or compliance expertise. You will have hands-on experience in areas such as cyber operations, infrastructure, cloud, security engineering, or security administration, and the technical acumen to understand how controls are designed, implemented, and evidenced in practice. Experience supporting compliance, audit, controls assurance, or risk management activities is essential, along with the ability to assess whether technical controls effectively satisfy regulatory, policy, and industry-standard requirements.

Key Responsibilities

• Support the execution of DT's Controls Assurance Testing Programme through a combination of automated and manual control testing activities.
• Translate regulatory, policy, and industry standard requirements into measurable control objectives, helping define how compliance requirements should be implemented and evidenced within technology environments.
• Partner with technical teams to understand the design and operation of security controls across identity, endpoint, network, infrastructure, cloud, and security operations domains.
• Identify opportunities to automate control testing through integrations with security and technology platforms, leveraging system data wherever possible to support continuous assurance and reduce manual testing effort.
• Develop and maintain automated testing logic, technical validation queries, control mappings, and evidence requirements to support repeatable and scalable testing activities.
• Perform manual control effectiveness testing where automation is not feasible, including evidence collection, validation, sampling, and assessment against defined testing criteria.
• Assess whether implemented controls meet the intent of applicable policies, standards, and compliance requirements, documenting findings and testing outcomes.
• Validate remediation activities submitted by control owners, reviewing technical and procedural evidence to determine whether identified deficiencies have been effectively addressed.
• Track control deficiencies and remediation activities through to closure, proactively engaging with stakeholders and escalating overdue actions where appropriate.
• Maintain control testing documentation, findings, remediation records, and workflow activities within ServiceNow IRM.
• Collaborate with DT Cyber Risk, IT Risk Management, Cyber Security, Engineering, and Operational teams to ensure control testing activities are technically accurate, well evidenced, and consistently executed.
• Support the Compliance Manager in evolving and maturing the Controls Assurance Testing Programme, including the development of testing methodologies, automation capabilities, reporting, and quality standards.
• Contribute to management reporting, KPI development, dashboard production, and assurance insights for compliance and risk stakeholders.
• Stay current with emerging technologies, cyber security practices, control assurance methodologies, and relevant regulatory and industry standards.

Personal independence

Regulation and controls are standard practice in our industry and Deloitte is no exception. These controls provide important legal protection for both you and the firm. We are subject to a number of audit regulations, one of which requires that certain colleagues abide by specific personal independence constraints (e.g., in relation to any financial interests and employment relationships). This can mean that you and your "Immediate Family Members" are not permitted to hold certain financial interests (shares, funds, bonds etc.) with audit clients of the firm, and also prohibitions on certain employment relationships (e.g., you are not permitted to hold a secondary employment role with SEC audit clients of the firm whilst being employed by the firm).
