Job description

Want to deliver tech with purpose, with people who care?

Join us in our mission to create solutions that help keep children safe online.

Who are we?

Headquartered in Perth, Australia, with offices around the world, Qoria is an ASX-listed global leader in child digital safety technology and services. We are a purpose-driven business operating under the Linewize brand in North America and Asia Pacific, the Smoothwall brand in the UK, the Qustodio brand in EMEA, and Qoria LK in Sri Lanka.

Our solutions are used by schools, school districts, and parental communities to protect children from harmful online content, identify students at risk based on their digital behaviours, and help teachers maintain focus and safe learning environments in the digital classroom. Today, 30,000 schools and 7 million parents rely on our solutions to help keep 25 million children safe across 180 countries worldwide.

The role

We're looking for a DevOps Engineer to make our infrastructure more scalable, secure and reliable while improving our deployment cycles.

You'd be joining the Ops team at Qustodio in Barcelona as its third member. It's a small team with a broad surface: we own the platform that the engineering and product teams build on, end to end. That means real autonomy and real ownership — you will set and drive a good part of your own work rather than pick up assigned tickets — and it also means the platform's problems are yours to diagnose, including the unglamorous ones.

What you'll be doing

• Migrating our workloads from EC2 to Kubernetes (EKS). This is the team's active priority and where a large share of the first months will go.
• Operating and evolving our EKS platform: Helm, GitOps with ArgoCD, progressive delivery, autoscaling.
• Owning production reliability with us — you'll take part in an on-call rotation with real page volume, and you'll be expected to drive incidents to a root cause rather than to a restart.
• Building infrastructure as code and automation that replaces manual and click-ops work.
• Treating internal engineering teams as your users: documenting, sharing knowledge, and making their path to production faster and safer.

What we're looking for

• 5+ years operating business-critical systems in high-availability production environments.
• Strong Linux and networking fundamentals, and a structured approach to diagnosing production problems.
• Solid production experience operating Kubernetes (EKS or equivalent) with Helm and GitOps (ArgoCD) — not just deploying onto a cluster somebody else runs.
• Strong AWS expertise across core services (compute, networking, storage, IAM).
• Proven experience with infrastructure as code (Terraform, CDK, CloudFormation) and configuration management (Ansible).
• Strong automation and scripting skills (Python, Bash).
• Experience operating production messaging/queueing and caching systems (RabbitMQ, Celery, Redis).
• Experience with CI/CD and observability.
• An ownership, product-oriented mindset, with a proactive approach to documentation and knowledge sharing.
• Strong communication skills in English, collaborating closely with engineering and product teams. Working Spanish, or the intention to get there, since much of the team works in it day to day.

Bonus points for experience with

• Progressive delivery and advanced Kubernetes autoscaling (ArgoCD, KEDA, Istio).
• Modernizing or migrating legacy infrastructure to Kubernetes.
• SRE practices such as SLOs and error budgets.
• Python/Django.
• Systems/network security, secrets management, compliance standards, and AWS cost optimization (FinOps).

Our stack

• Cloud: AWS (multi-account) and GCP.
• Containers & orchestration: Kubernetes (EKS), Helm, ArgoCD — with Istio, KEDA and Argo Rollouts.
• Infrastructure/Configuration as code: AWS CDK, Terraform, CloudFormation, Ansible, Puppet.
• CI/CD: Jenkins, GitHub Actions (hybrid with self-hosted runners).
• Data & messaging: RabbitMQ, Celery, Redis (ElastiCache), RDS, DynamoDB, S3.
• Backend we support: Python/Django services, feature flags and configuration management.
• Networking & security: Tailscale VPN, Route53, SOPS, Upwind, Sentry, SonarCloud, Snyk, Crowdstrike.

Salary range : €60,000 - €70,000 plus benefits
