Site Reliability Engineer (AWS)

Job Title: Site Reliability Engineer (AWS)

Location: Dublin / Hybrid (2 days)

Type: Permanent

We’re looking for a Site Reliability Engineer (Mid-Level) who loves solving complex problems, automating everything possible, and keeping systems running smoothly. You’ll be right in the mix of building reliable, scalable, and high-performing cloud environments — mainly in AWS — while helping our dev teams ship great products faster and with fewer headaches.

This is a hands-on role for someone who values automation, ownership, and collaboration over silos and manual fixes. You’ll also join our on-call rotation (don’t worry, it’s shared and well-supported).

What you’ll be doing

• Build and manage robust, highly available AWS infrastructure using tools like Terraform or CloudFormation
• Maintain and improve CI/CD pipelines (Azure DevOps) for automated deployments and testing
• Work with Docker and Kubernetes (EKS/ECS) to orchestrate containerized workloads
• Automate as much as possible — from monitoring and alerting to deployment workflows
• Define and track reliability metrics (SLIs/SLOs/error budgets)
• Dive into incidents, lead root cause analysis, and make sure they don’t happen again
• Build out observability solutions (CloudWatch, Prometheus, Grafana, ELK, etc.)
• Partner with development and security teams to improve app reliability and platform performance
• Keep security tight — IAM roles, secrets management, and network boundaries are second nature

What makes you a great fit

• Around 5–7 years in IT, with 3+ years in SRE, DevOps, or Cloud Engineering
• Deep hands-on experience with AWS (EC2, VPCs, IAM, S3, RDS, CloudWatch, ALB/ELB, Route53)
• Solid experience building CI/CD pipelines with Azure DevOps
• Comfortable managing Linux and/or Windows environments at scale
• Strong background in Docker and Kubernetes — you know your way around clusters, scaling, and deployments
• Skilled with Infrastructure as Code (Terraform, CloudFormation)
• Confident scripting in Bash or Python for automating all the boring stuff
• Experienced in monitoring, logging, and alerting — you believe in metrics, not guesswork
• Understand the core of SRE: SLIs/SLOs, incident management, postmortems, capacity planning
• Always exploring ways to make cloud systems faster, more resilient, and more cost-efficient

Who you are

• Obsessed with uptime, reliability, and automation
• Open communicator who thrives in cross-team collaboration
• Takes full ownership of what you build and run
• Always curious about the latest in SRE and cloud-native tech
