Your work goes beyond reactive support: you proactively prevent technical debt, drive cost optimization, automate manual toil, and apply ITIL best practices to ensure consistent, high-quality outcomes.
You'll work cross-platform (not domain-siloed), collaborate closely with networking, security, application, and DevOps teams, and lead vendor escalations when needed.
If you are passionate about DevOps culture, continuous improvement, and delivering world-class infrastructure reliability, this role is for you.
What you'll do · Lead the day-to-day operation, maintenance, and performance of complex AWS cloud environments.
· Act as the primary escalation point for platform issues, driving rapid incident response and resolution.
· Manage identity and access controls, ensuring secure provisioning and adherence to least-privilege principles.
· Drive continuous optimisation initiatives to improve platform performance, reliability, security, and efficiency.
· Identify and implement cloud cost optimisation strategies, leveraging FinOps best practices to maximise value.




· Review and evolve cloud architectures using the AWS Well-Architected Framework, delivering modernisation and scalability improvements.
· Oversee platform lifecycle management, including upgrades, patching, and security governance with minimal disruption.
· Lead, mentor, and develop a high-performing cloud engineering team while building trusted client relationships and delivering exceptional customer outcomes.
Ideally you'll have · Extensive hands-on experience designing, managing, and optimising AWS cloud environments at scale.
· Strong knowledge of Infrastructure as Code (IaC), developer experience best practices, and FinOps principles.
· Solid understanding of cloud networking, security, governance, and compliance frameworks.
· A proactive, outcomes-focused mindset with a passion for continuous improvement and operational excellence.
· Proven experience leading, mentoring, or managing technical teams within Cloud, DevOps, Operations, or Managed Services environments.
· Exceptional communication and stakeholder management skills, with the ability to translate complex technical concepts for diverse audiences.
· Robust troubleshooting, incident management, and problem-solving capabilities, with the ability to perform effectively under pressure.
· AWS certifications such as AWS Certified Solutions Architect Professional or DevOps Engineer Professional will be highly regarded.
