Head of Infrastructure

Deployment governance and change visibility

• Create common deployment governance and production change visibility across DTS.
• Defining minimum standards for production deployment processes.
• Establishing central visibility of who deployed what, when and where.
• Supporting release gates, change records and deployment auditability.
• Enabling teams to use their own deployment tooling while reporting into a common deployment record.
• Supporting mechanisms to pause or control deployments during high-risk or sensitive periods.
• Ensuring deployment activity can be correlated with incidents, outages and platform instability.

Observability, monitoring and operational visibility

• Define common observability and monitoring expectations across DTS platforms.
• Establishing standards for logging, metrics, tracing, alerting and dashboards.
• Ensuring product teams provide the right operational and security telemetry.
• Supporting cross-platform visibility for incidents, chained attacks, service degradation and performance issues.
• Working with Security Operations on SIEM, SOC and threat detection requirements.
• Ensuring infrastructure and application events are visible to the right operational teams.

Reliability, resilience and operational readiness

• Ensure DTS platforms meet agreed reliability and resilience expectations.
• Defining standards for service-level objectives, availability, recovery, incident readiness and operational maturity.
• Working with platform teams to ensure services are designed and operated to appropriate reliability levels.
• Supporting disaster recovery, business continuity and operational readiness requirements.
• Ensuring teams have appropriate runbooks, escalation paths and incident response processes.
• Tracking recurring operational issues and ensuring they are addressed through the appropriate teams.

Infrastructure security alignment

• Work with Security and Compliance to ensure infrastructure standards support DTS security requirements.
• Ensuring infrastructure standards reflect security requirements around access control, network exposure, ingress/egress, secrets, logging and hardening.
• Working with the Cloud and Platform Security Lead where applicable.
• Ensuring teams provide evidence that required infrastructure security controls are in place.
• Supporting the reduction of unnecessary public exposure across DTS services.
• Ensuring infrastructure governance supports audit, compliance and client assurance requirements.

Cost visibility and capacity oversight

• Establish infrastructure cost transparency and capacity visibility across DTS.
• Defining standards for cloud cost reporting and allocation.
• Ensuring teams can report infrastructure cost by product, platform, client or workload where appropriate.
• Identifying areas of duplication, waste or inefficient infrastructure use.
• Supporting capacity planning across growing DTS platforms and AI/data workloads.
• Providing leadership with clear visibility of infrastructure cost drivers and optimisation opportunities.

Relationship with TechOps

• Work closely with the TechOps function while maintaining clear ownership boundaries.
• TechOps is responsible for day-to-day delivery operations, environment support, release coordination and operational support to engineering teams.
• The Head of Infrastructure is responsible for defining infrastructure standards, governance, shared visibility, reliability expectations and cross-DTS platform coordination.
• Partnering with TechOps to ensure infrastructure standards are practical in delivery workflows.
• Using TechOps feedback to identify recurring operational issues and improvement opportunities.
• Avoiding duplication of TechOps responsibilities.
• Ensuring delivery operations and infrastructure governance operate as a joined-up capability.
• Clarifying when issues should be handled by TechOps, product engineering, infrastructure teams, security or DTS leadership.

Common tooling and shared platform capabilities

• Identify and coordinate shared tooling where it benefits DTS.
• Assessing where common tooling should be used for deployment governance, observability, incident management, cost reporting, infrastructure inventory and operational reporting.
• Avoiding unnecessary standardisation where teams need specialist tooling.
• Supporting common integration points rather than forcing all teams onto identical infrastructure stacks.
• Defining central capabilities that allow teams to remain autonomous while providing DTS-wide visibility.
• Working with Architecture and Infrastructure teams to introduce shared services where there is clear value.

Who you'll be working with:

The Head of Infrastructure will be accountable for:

• Common DTS infrastructure standards and operating model.
• Federated infrastructure governance across DTS platforms.
• Alignment of infrastructure activity with DTS leadership direction.
• Deployment governance and production change visibility.
• Observability, monitoring and operational visibility standards.
• Reliability, resilience and operational readiness expectations.
• Infrastructure cost visibility and reporting.
• Clear distinction and partnership between Infrastructure and TechOps.
• Infrastructure alignment with DTS architecture, security and compliance requirements.
• Ensuring platform teams retain autonomy while meeting common DTS standards.

What you'll need:

The successful candidate will have:

• Multiple years of experience overseeing infrastructure, platform engineering, SRE, DevOps, cloud operations or technology operations leadership.
• Strong understanding of cloud platforms, deployment models, observability, reliability, infrastructure governance and operational resilience.
• Experience working in federated or matrixed technology organisations.
• Ability to define standards and operating models without over-centralising delivery.
• Strong understanding of CI/CD, deployment governance, incident management, monitoring, logging and production operations.
• Good knowledge of infrastructure security, access control, network exposure, cloud posture and operational risk.
• Ability to influence senior technical leaders and product/platform teams without relying solely on line authority.
• Strong stakeholder management skills across Engineering, Architecture, Security, Product, TechOps and Enterprise Technology.
• Ability to balance autonomy, consistency, security, reliability and delivery speed.
• Clear communication skills and the ability to create practical standards that teams can adopt.

Leadership expectations

The Head of Infrastructure is expected to:

• Act as a coordinator and enabler, not a central blocker.
• Respect the autonomy of specialist product and platform teams.
• Create clarity around infrastructure standards and expectations.
• Work closely with DTS senior leadership and take direction from agreed architecture and security strategy.
• Build trust with TechOps, Engineering, Infrastructure, Security and Product teams.
• Challenge teams where infrastructure practices create risk, poor visibility or operational weakness.
• Avoid unnecessary centralisation while reducing fragmentation where it creates risk.
• Provide clear reporting on infrastructure health, cost, reliability and operational readiness.

Success measures

Success in the role will be measured by:

• DTS having clear and adopted infrastructure standards.
• Product and platform teams operating autonomously while meeting common DTS expectations.
• Improved visibility of deployments and production changes across DTS.
• Better observability and monitoring across DTS platforms.
• Clearer understanding of infrastructure ownership and operational accountability.
• Improved ability to correlate incidents
