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.
