Senior DevOps Engineer

We are working with a globally recognised media and technology organisation to hire a Senior DevOps Engineer into their Belfast engineering team. This is a hands-on senior role sitting at the heart of a live re-platforming project, migrating a legacy application into AWS and modernising it for cloud-native best practices. You will work alongside an experienced senior engineer to drive this forward, with real ownership and influence over architecture decisions, not a ticket-by-ticket delivery role. You will collaborate with cross-functional teams, lead infrastructure improvements, and help shape the DevOps practice across the organisation. If you want genuine end-to-end ownership of a production environment and the chance to leave a real technical mark on a meaningful project, this is a strong opportunity to do that. What you will be doing:

• Designing and implementing robust, scalable, and secure infrastructure on AWS
• Driving the migration of legacy systems into cloud-native architectures
• Developing and maintaining infrastructure-as-code using Terraform or comparable tooling
• Improving system reliability, observability, and cost-efficiency across environments
• Modernising CI/CD practices to enable safe, rapid delivery across multiple environments
• Supporting incident response and improving operational visibility through monitoring, logging, and tracing
• Mentoring junior engineers and contributing to engineering standards and design reviews

• Deep, broad AWS experience across the full ecosystem, not siloed knowledge of individual services
• Strong Linux fundamentals, considered essential for this role
• Strong networking knowledge and an understanding of distributed architectures
• A track record of owning and running production environments end to end
• Experience with containerised workloads in production using Docker, ECS, or Kubernetes
• Proficiency in Terraform or a comparable infrastructure-as-code tool
• Strong scripting skills in Bash, Python, Go, or similar

Useful but not essential:

• Experience with Ansible, Cloudflare, PostgreSQL, or MySQL in production
• Familiarity with observability platforms such as Datadog, Splunk, or ELK
• Exposure to multi-tenant SaaS architectures
• Experience leading or contributing to cloud migration projects
