Hybrid: 2–3 days per week onsite in Co. Donegal

CompuStaff is recruiting a Senior DevOps / Platform Engineer for a major global financial services organisation undergoing significant technology transformation.

This is a senior, hands-on role focused on modernising CI/CD, building scalable cloud platforms and improving operational reliability across AWS, Azure and on-premises environments. You’ll help development teams adopt better engineering practices while shaping the tools, standards and automation used across the organisation.

What You’ll Do

  • Standardise CI/CD using GitHub Actions, including reusable workflows, composite actions, runner strategy, approvals and quality gates.
  • Automate infrastructure provisioning and configuration using Terraform, CloudFormation and Ansible.
  • Build secure, reliable deployment pipelines supporting blue/green and canary releases.
  • Implement GitOps deployment and environment-promotion patterns using tools such as Argo CD, Flux, Helm or Kustomize.
  • Work with engineering teams to understand technical challenges and deliver practical platform solutions.
  • Establish SRE practices, including SLIs/SLOs, error budgets, runbooks, automated remediation and service-health dashboards.
  • Improve observability across production services using metrics, logs and distributed tracing.
  • Embed security controls into CI/CD workflows and support incident response, platform hardening and audit readiness.
  • Help introduce effective FinOps practices covering cloud-cost visibility, tagging, budgeting, rightsizing and optimisation.
  • Develop automation using Python, Shell, PowerShell, JavaScript or Groovy.

What You’ll Bring

  • Approximately 4-6 years’ experience in DevOps, Platform Engineering, Cloud Engineering or SRE.
  • Strong hands-on experience with AWS and/or Azure.
  • Advanced CI/CD experience, ideally using GitHub Actions, with exposure to Jenkins migrations or integrations.
  • Experience with infrastructure as code, particularly Terraform or CloudFormation.
  • Strong knowledge of Docker, Kubernetes and cloud container platforms such as EKS, ECS or AKS.
  • Experience with production monitoring and observability tools such as Splunk, Dynatrace, Datadog, Prometheus, Grafana or OpenTelemetry.
  • Good understanding of networking, DNS, routing, messaging and microservices.
  • Working knowledge of cloud security, IAM, secrets management, logging and vulnerability remediation.
  • Automation or development experience using Python, JavaScript, Groovy, Shell or PowerShell.
  • Strong communication and documentation skills, with the ability to work effectively with engineers and business stakeholders.

Nice to Have

  • AWS or Azure certifications.
  • Experience implementing SRE principles and measurable service-level objectives.
  • Exposure to SAST, DAST, software composition analysis or cloud-security posture management.

This is an excellent opportunity to influence the direction of a major platform-engineering transformation rather than simply maintaining an established environment.

Please note that this is a hybrid position requiring attendance at the company’s Co. Donegal office 2–3 days per week. It is not a fully remote role.
