Senior DevOps Engineer | Belfast | Hybrid | Up to £70,000
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

What we are looking for:

  • 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

The details:

  • Location: Belfast
  • Working pattern: Hybrid, with core office days on Monday and Thursday
  • Benefits include private medical and pension matching

Skills:
DevOps AWS Terraform Linux

Benefits:
Work From Home Pension + Healthcare
