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.
