Job type: Permanent
Salary: €70,000 – €100,000
Role location: Hybrid or Remote (candidates must be based in Greece)

The company

A fast-growing company operating in the cybersecurity and data protection space, supporting global clients to safeguard critical information and maintain operational excellence. The platform sits at the intersection of cloud infrastructure, reliability, and security, operating at meaningful scale and complexity.

Role and responsibilities

I’m recruiting a Senior Site Reliability Engineer to take ownership of the reliability, performance, and scalability of mission-critical systems. You’ll play a key role in ensuring highly available, secure platforms while shaping best practices across cloud infrastructure, automation, and observability.

This is a high-impact role with real ownership, working closely with engineering teams to build resilient systems that operate at scale.

What You’ll Be Doing

  • Owning the reliability, availability, and performance of core production systems.

  • Designing, building, and maintaining scalable cloud infrastructure on AWS.

  • Driving automation across infrastructure, deployment, and operational workflows.

  • Supporting and evolving Kubernetes-based platforms (EKS) and containerised services.

  • Building and maintaining CI/CD pipelines and GitOps workflows.

  • Implementing and improving observability, monitoring, alerting, and incident response practices.

  • Troubleshooting complex, distributed system issues across microservices and multi-region environments.

  • Contributing to architectural decisions around scalability, resilience, and failover.

Job requirements

  • Proven experience as an SRE or DevOps Engineer in large-scale production environments.

  • Strong AWS expertise (Terraform, CloudFormation, CDK).

  • Hands-on experience with Kubernetes (EKS) and Docker.

  • Solid experience with CI/CD tooling (GitHub Actions, CircleCI, Argo) and GitOps principles.

  • Deep understanding of observability, monitoring, and system health.

  • Experience designing for scalability and failover across multi-region clusters.

  • Comfortable operating in high-availability, security-conscious environments.

Bonus skills

  • Experience with Kafka, Java (Spring), Python, APIs, and API Gateway.

  • Strong Linux systems knowledge.

  • Background in cybersecurity, fintech, or other data-sensitive industries.

Benefits

  • Competitive salary (€70–100k).

  • Hybrid or fully remote working (within Greece).

  • High ownership and influence over reliability and infrastructure strategy.

  • Work on complex, large-scale systems with real-world impact.

  • Collaborative engineering culture focused on quality, automation, and continuous improvement.
