Senior Identity and Access Security Engineer

Why we're hiring:

The Senior Identity and Access security Engineer is responsible for governing who, and what, can access DTS systems, data, APIs, tools, workflows and AI-enabled capabilities.

This is a hands-on governance and control role, reporting into the SVP Security and Compliance. The role ensures that access across DTS is appropriate, auditable, reviewed, least-privileged and aligned with security, privacy, compliance and client commitments.

The scope covers traditional human access, external users, privileged access, service accounts, machine identities, API keys, tokens, dataset access, and the emerging governance of AI agents and agentic workflows.

The role will work closely with Architecture, Security, Product, Engineering, Infrastructure, Privacy, Legal/DPO, TechOps, Enterprise Technology and the ISMS and Risk Officer to ensure DTS has a clear and controlled model for access across platforms such as WPP Open, Choreograph, InfoSum, Open Intelligence, Resolve and related DTS capabilities.

What you'll be doing:

1. Identity and access governance framework

Define and maintain the access governance framework for DTS.

This includes:

• Defining access governance standards, processes and control expectations.
• Establishing how access should be requested, approved, provisioned, reviewed, revoked and evidenced.
• Ensuring access governance covers internal users, external users, clients, partners, vendors, service accounts, machine identities and AI agents.
• Aligning identity and access governance with DTS architecture, security, privacy, compliance and data governance requirements.
• Ensuring access governance is practical for product and engineering teams to implement.

2. Access reviews and recertification

Own the process for regular access reviews and recertification across DTS.

This includes:

• Defining the scope, frequency and evidence requirements for access reviews.
• Coordinating access reviews for critical DTS systems, production environments, privileged roles, sensitive datasets, client-facing platforms and administrative tools.
• Ensuring access review outcomes are tracked, remediated and evidenced.
• Identifying stale, excessive, orphaned or poorly owned access.
• Escalating overdue, high-risk or unresolved access issues through the appropriate governance channels.

3. Privileged access governance

Ensure privileged access across DTS is properly controlled, justified and auditable.

This includes:

• Reviewing access to production systems, cloud environments, security tools, databases, CI/CD tooling, administrative consoles and sensitive platforms.
• Supporting least-privilege, just-in-time and time-bound access models where appropriate.
• Working with Cloud and Platform Security and Infrastructure to improve privileged access controls.
• Ensuring privileged access risks are visible in the DTS risk register where required.

4. External user, client and partner access governance

Govern access for external users, clients, agencies, partners and vendors.

This includes:

• Defining standards for external user onboarding, approval, permissions, expiry and offboarding.
• Ensuring external access has a clear business owner and justification.
• Supporting access governance across client workspaces, agency environments, partner integrations and shared collaboration areas.
• Working with Product and Engineering to ensure tenant, workspace and client-level isolation is appropriately governed.
• Tracking risks related to stale accounts, vendor access, partner permissions and external user overprivilege.

5. Service account, machine identity and API access governance

Govern non-human access across DTS systems and platforms.

This includes:

• Defining standards for service accounts, machine identities, automation users, API keys, tokens, secrets and integration credentials.
• Ensuring non-human access has clear ownership, purpose, scope, rotation, expiry and auditability.
• Working with Product, Engineering, Cloud Security and Infrastructure to reduce unmanaged credential risk.
• Ensuring service accounts and machine identities are included in access reviews.
• Supporting stronger governance of API access, token issuance, credential lifecycle and integration permissions.

6. AI and agentic access governance

Define and oversee the governance model for AI agents and agentic workflows across DTS.

This includes:

• Defining how AI agents are identified, permissioned, monitored, reviewed and revoked.
• Ensuring agents have clear ownership, scoped permissions and auditable actions.
• Defining which agent actions require human approval or additional control.
• Governing agent access to APIs, tools, datasets, workflows, client environments and production capabilities.
• Ensuring agents act within delegated authority and cannot exceed the permissions of the user, system or business process they represent.
• Working with Product, Architecture and Security to ensure agentic workflows are designed with clear action boundaries.
• Working with the Product, Application and Offensive Security Lead to test whether agent permissions and action boundaries can be bypassed.
• Working with Privacy Engineering to ensure AI access models support permitted use, minimisation and data protection requirements.

7. Data access governance

Govern access to sensitive, client, partner and WPP-owned data across DTS.

This includes:

• Defining standards for dataset access approval, review, revocation and evidence.
• Supporting data classification from an access-control and security-governance perspective.
• Ensuring access to sensitive data is role-based, purpose-based, least-privileged and auditable.
• Supporting controls for cross-client, cross-market, cross-agency and partner data access.
• Ensuring data access governance supports InfoSum, Open Intelligence, Resolve, WPP Open and other DTS data collaboration use cases.
• Working with Privacy Engineering on data minimisation, permitted use, retention and privacy-by-design requirements.
• Ensuring data access risks are surfaced through the DTS risk process.

8. Governance of access to tools, workflows and actions

Ensure access governance extends beyond systems and datasets into tools, workflows and actions.

This includes:

• Defining governance for access to operational tools, workflow automation, orchestration systems, AI tools and administrative actions.
• Ensuring high-risk actions are subject to appropriate approval, logging and monitoring.
• Supporting segregation of duties across sensitive workflows.
• Ensuring automated workflows and agents have clearly scoped authority.
• Working with Security Operations to ensure high-risk access and actions are visible in monitoring and detection processes.

9. Auditability, evidence and reporting

Maintain clear evidence of access governance and support audit and assurance requirements.

This includes:

• Producing access governance evidence for SOC 2, ISO 27001, client assurance, internal audit and risk reviews.
• Working with the ISMS and Risk Officer to ensure access controls, reviews, exceptions and remediation actions are documented.
• Reporting on access review completion, high-risk access, overdue actions and access control gaps.
• Supporting client and audit questions related to identity, access, privileged roles, service accounts, AI agents and data access.
• Ensuring access governance is repeatable, measurable and auditable.
