Job Description – Senior Cloud Engineer (SRE & AWS)
Dublin, Ireland
Overview
The Cloud Engineering team is responsible for managing, supporting, and continuously improving our cloud and hybrid infrastructure platforms.
We are looking for a strong hands-on Senior Cloud Engineer with deep AWS expertise to design, implement, secure, automate, and operate highly available cloud infrastructure across internal and client-facing environments.
AWS will be the primary cloud platform for this role. The engineer should also have a good working knowledge of other major cloud platforms such as Microsoft Azure and/or Google Cloud Platform (GCP), as some of our clients operate on these platforms or have hybrid/on-premises environments that integrate with our services.
The role focuses on production reliability, cloud infrastructure, automation, observability, security, incident management, disaster recovery, performance, cost optimization, and continuous improvement.
This is not a traditional infrastructure support role. The successful candidate is expected to use engineering and automation to reduce operational toil, eliminate recurring incidents, improve platform reliability, and continuously enhance operational efficiency.

- Working knowledge of core Azure and/or GCP services including compute, networking, storage, identity, security, and monitoring.
- Troubleshoot connectivity and integration issues across AWS, other public clouds, and on-premises infrastructure.
- Understand hybrid connectivity patterns including VPN, dedicated connectivity, DNS, routing, identity federation, and secure data integration.
- Participate in client technical discussions involving non-AWS cloud environments where required.
- Apply consistent operational, security, reliability, and governance standards across hybrid environments.
- AWS depth is mandatory.
- Azure/GCP experience is an advantage and should not substitute for strong AWS production experience.
3. Automation & Infrastructure as Code
- Develop and maintain reusable Terraform modules and infrastructure automation frameworks.
- Automate infrastructure provisioning, configuration, patching, compliance checks, and operational activities.
- Develop automation using Python and/or Shell scripting.
- Build self-service capabilities to reduce manual operational activities.
- Implement automated remediation and self-healing capabilities where appropriate.
- Continuously identify opportunities to eliminate operational toil through automation.

- Participate in security audits, vulnerability assessments, and closure of audit findings.
- Ensure cloud infrastructure complies with organizational, client, regulatory, and security requirements.
- Implement and maintain appropriate security guardrails and controls.
- Work closely with Security teams to identify and remediate cloud security risks.
7. Disaster Recovery & Resilience
- Design, implement, and maintain AWS disaster recovery solutions.
- Participate in DR and failover testing and validation.
- Ensure infrastructure meets defined RTO and RPO requirements.
- Identify and remediate BCP/DR gaps.
- Support multi-AZ and multi-region resilience initiatives.
- Develop and maintain DR procedures, runbooks, and recovery documentation.
8. Performance, Capacity & AWS Cost Optimization
- Monitor infrastructure capacity and performance and proactively identify bottlenecks.
- Conduct performance and capacity analysis and recommend improvements.
- Support scalability and resilience engineering initiatives.
- Identify and implement AWS cost optimization opportunities.
- Apply right-sizing, autoscaling, resource optimization, scheduling, and architectural improvements to reduce cloud spend.
- Identify idle and underutilized resources.
- Work with Architecture and Engineering teams to improve the cost/performance profile of the platform.
9. Production Operations & Reliability
- Own the operational health, availability, performance, and reliability of AWS cloud environments.
- Lead resolution of high-severity production incidents, including participation in client bridge calls where required.
- Troubleshoot complex infrastructure, networking, application, and cloud-platform issues.
- Lead technical Root Cause Analysis (RCA) for major incidents and drive corrective and preventive actions through to completion.
- Identify recurring incidents and implement permanent engineering solutions to prevent repeat failures.
- Establish and maintain cloud operational standards, guardrails, runbooks, and best practices.
