1. Role purpose

The Security Lead is our accountable security owner for the managed service. The role leads on, and has day-to-day operational responsibility for, service security — working in collaboration with the client's Information & Security function, the client Security Operations Centre (SOC), the internal delivery team, and the third-party software vendor. This is a contractually-named DV-cleared key role and is a PASS/FAIL requirement under the Conditions of Participation.

2. Context

The service processes HR, Finance and Project data including OFFICIAL-SENSITIVE personal and financial data of UK civil servants and locally-engaged staff across a large international footprint. The contractual security regime spans UK Government security policy, NCSC HMG IAS5, GDPR/DPA 2018, PCI-DSS where applicable, and the client's Cyber Security Incident Response Plan. The SOC is operated 24/7 by the client and the Supplier is required to integrate, report into and support it.

3. Key accountabilities

• Lead and own day-to-day operational responsibility for service security across OPERATE and DEVELOP.
• Advise the client on security status and matters; identify and address risks; continuously maintain and improve the security posture.
• Act as the authoritative security voice in the client's Design Authority and Enterprise Architecture forums for security-impacting changes.

3.2 Clearance, vetting and access

• Own the clearance pipeline: ensure all Supplier staff who hold, process or discuss client data are SC-cleared UK Nationals as a minimum, and that the named DV roles plus all 'full administrator' staff are DV-cleared UK Nationals.
• Manage client-sponsored SC and DV applications from the start of Transition, conducting reasonable diligence checks in advance.
• Oversee joiner/mover/leaver, privileged access management (PAM), role-based access control (RBAC), and the monthly audit report on RBAC and environment access.

• Support the SOC in resolving security incidents; document security use cases with the SOC; implement, maintain and support those SOC infrastructure components hosted within the cloud infrastructure.

3.4 Assurance, audit and compliance

• Treat information security issues, weaknesses or deficiencies identified by the client as Security Incidents under the client's Cyber Security Incident Response Plan.
• Provide client auditors with access to security documentation, configurations of security-enforcing technologies, standards and procedures.
• Collaborate with the client to plan and conduct annual PenTest and regular Disaster Recovery exercises.
• Ensure GDPR / DPA 2018 obligations are met; oversee data retention, secure disposal, lawful processing, and Data Protection Impact Assessments where required.

3.5 Technical security controls

• Define, document, agree and maintain Standard Operating Procedures for system administration and maintenance, with procedural controls per user role.
• Ensure authorisation controls prevent extraction of information assets without legitimate need.
• Ensure only client-issued devices are used to connect to the service in delivery.
• Maintain a data back-up policy aligned to Business Impact Assessment and the client's retention policy.

• Hands-on experience integrating with a UK Government SOC, including SIEM reporting, security use case design and incident response co-ordination.
• Practical experience of Oracle Cloud security — OCI IAM, vault, network security, audit, PAM — and Oracle SaaS application security (HCM/ERP/EPM RBAC, segregation of duties, data masking).

• Proven experience leading UK Government clearance pipelines: SC and DV sponsorship, due diligence, joiner/mover/leaver workflows.
• Strong written communication for government-grade audit, assurance and governance reporting.
• Comfortable as a named security accountable individual in formal governance and contractual reporting.
