What We Are Looking For

We are looking for a Junior DevOps Engineer to join our Engineering team and grow into a key contributor on our product critical path: deployment, orchestration, observability, and secure communication. Working alongside senior engineers, you will learn and apply modern DevOps practices while contributing to real-world production systems from day one.

What You Will Be Doing

• Write programs/scripts and automation to streamline routine operational tasks

• Assist in building, maintaining, and improving CI/CD pipelines and release processes across product teams

• Support cloud infrastructure management using Infrastructure-as-Code (Terraform/Terragrunt, Helm charts, Bicep/ARM) under senior guidance

• Help operate and maintain Kubernetes clusters (AKS) and supporting services

• Contribute to GitOps workflows using Argo CD for declarative, auditable deployments

• Help maintain observability tooling — metrics, logging, alerting, tracing (Prometheus, Grafana, Azure Monitor, OpenTelemetry)

• Manage on-prem and cloud resources, assist with cost monitoring, and support infrastructure health checks across Azure environments

• Participate in incident management — join on-call rotation with senior engineer mentorship, assist in triage, and contribute to post-incident reviews

• Collaborate with product engineering, QA, security, and support teams as part of cross-functional delivery

• Document procedures, runbooks, and learnings with clarity and consistency

What You Will Bring

Required

• 2+ years of hands-on experience in DevOps, SRE, or systems/cloud engineering

• Strong knowledge of at least one programming/scripting language (e.g., Python, Bash, PowerShell, Go)

• Good understanding of cloud platforms (Microsoft Azure preferred)

• Familiarity with containers and Kubernetes concepts (AKS preferred)

• Exposure to CI/CD concepts and experience with at least one CI/CD tool (Azure DevOps preferred)

• Exposure to Infrastructure-as-Code concepts (e.g., Terraform, Helm, or similar)

• Basic understanding of Linux systems and networking fundamentals (TCP/IP, DNS, firewalls)

• Eagerness to learn and grow in areas such as GitOps, observability, security, and distributed systems

• Willingness to participate in an on-call rotation with mentorship and support

• Good communication skills — you can explain what you did and ask for help clearly

• A collaborative, team-first attitude

• First-principles thinking — you break problems down to root causes before jumping to solutions

• Continuous learning mindset — you stay current, experiment with new tools, and share knowledge with the team

• You dare to ask questions and challenge decisions with solid reasoning; respectfully and constructively

• Collaborative, flexible, and friendly — you thrive in a diverse, globally distributed team and bring positive energy to every interaction

Bonus Points

• Relevant certifications in Azure (AZ-104), AWS, Kubernetes (CKAD), or Linux

• Exposure to GitOps practices and tools (e.g., Argo CD, Flux)

• Familiarity with monitoring and logging tools (Prometheus, Grafana, Azure Monitor)

• Experience with Microsoft Windows & Microsoft environments or Windows-based troubleshooting

• Knowledge of cloud and container security basics

• Coursework or personal projects involving microservices, event-driven architectures, or distributed systems

• A degree in Computer Science, Engineering, or a related field (or equivalent practical experience)

• Security-first and developer experience mindset — you care about doing things the right way, not just the fast way

Non-Negotiables

• Must be in Ireland with valid work visa or citizenship

• Must have solid hands-on experience with programming and foundational experience with cloud/infrastructure concepts — through work or valid internships

• Must demonstrate clear communication skills with team members, stakeholders, and the wider engineering org

• Willing to commute to office two/three days a week
