Senior DevOps Engineer - Operations
Job Description
Exceptional Senior DevOps Engineer - Operations required for our Managed Service Platform, focusing on AWS and Cloud infrastructure. This isn’t your traditional break/fix support desk. You will be leading a high-performing team of platform engineers dedicated to maintaining, securing, and religiously optimizing cloud platforms. As a Senior DevOps Engineer - Operations, you will own the complete lifecycle of medium-to-large platform components — from design through to continuous improvement. You'll balance operational excellence with deep technical strategy, acting as a trusted advisor and technical leader. 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. · Strong 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.
