• Build, lead, and mentor globally distributed platform engineering teams.
• Instil a DevOps culture of ownership, automation, and continuous improvement.
• Oversee cloud infrastructure (AWS & GCP), Kubernetes platforms, and global networking.
• Drive automation-first practices, including infrastructure-as-code, GitOps, and immutable deployments.
• Establish and monitor SLOs, SLIs, and SLAs to ensure reliability and performance.
• Lead incident management, blameless postmortems, and resilience engineering initiatives.
• Own FinOps and cloud operations, ensuring platforms are cost-efficient and financially accountable.
• Partner with Finance and Product to forecast cloud spend and optimise resource usage.
• Own the end-to-end CI/CD ecosystem, ensuring all teams can release safely and quickly.
• Provide self-service pipelines, test automation, and deployment tooling.
• Embed security and compliance checks directly into the CI/CD process.
• Champion a paved-road developer experience to reduce friction and accelerate delivery.
• Partner with Security Engineering to embed zero-trust, modern IAM, and end-to-end TLS.
• Drive adoption of secrets management and certificate lifecycle automation.
• Ensure all platform services and pipelines are compliant with PCI DSS, GDPR, and local regulations.
• Lead global networking strategy, ensuring secure, resilient, low-latency connectivity.
• Build automation and observability into networking for proactive detection and rapid recovery.
• Collaborate with product and business leaders to anticipate scaling needs and influence technology strategy.
• Represent the platform function with external partners, regulators, and customers.

Qualifications

• Minimum 10 years of proven experience leading platform, SRE, or DevOps functions at scale in mission-critical environments.
• Deep expertise in cloud-native architectures (AWS, GCP), Kubernetes, CI/CD, networking, and distributed systems.
• Track record of driving automation with infrastructure-as-code, GitOps, and observability platforms.
• Strong SRE mindset with experience applying SLIs, SLOs, error budgets, and resilience engineering.
• Security-first approach with experience embedding compliance into automated pipelines.
• Strong leadership skills with a track record of building high-performing, distributed engineering teams (global or remote-first context).
