Athens, Attica, Greece Sphynx Full time €40,000 - €80,000 per year

We are looking for a DevOps & IT Specialist with a strong background in Microsoft Azure, cloud infrastructure, and secure deployment practices. This role bridges the gap between infrastructure, security, and development by automating cloud operations, maintaining robust CI/CD pipelines, and supporting internal IT needs. You will be instrumental in ensuring our systems are secure, scalable, and reliable—both for internal use and for client-facing deployments.

Key Responsibilities
DevOps & Cloud Infrastructure
  • Design, implement, and maintain Azure-based infrastructure using Infrastructure as Code (e.g.,Terraform).
  • Manage and optimize CI/CD pipelines (GitLab CI) for secure and automated deployments.
  • Monitor infrastructure and application performance; set up alerts, logging, and incident response mechanisms (e.g., Azure Monitor, Log Analytics, Sentinel).
  • Collaborate with development teams to support cloud-native application delivery and microservices.
  • Monitor and troubleshoot production environments, ensuring high availability and performance.
  • Implement security best practices across cloud deployments (e.g., identity and access management, encryption, vulnerability scanning).
Network Engineering
  • Design and maintain virtual networks, subnets, NSGs, routing, and VPN gateways within Azure.
  • Implement hybrid networking (on-prem to Azure) and secure site-to-site or point-to-site VPNs.
  • Manage and secure Azure Firewall, Azure Front Door, Application Gateways, and WAFs.
  • Ensure network segmentation, traffic control, and zero trust principles are enforced across environments.
  • Support load balancing, DNS management (Azure DNS), and traffic optimization for high availability.
  • Work with security teams to ensure compliance with network-related controls and best practices (e.g., logging, IDS, encryption-in-transit).
Requirements
  • 3–5+ years of experience in DevOps, Cloud Engineering, or IT Operations.
  • Deep hands-on experience with cloud-native architectures (preferrably Azure)
  • Solid knowledge of routing, firewalls, VPNs, NAT, DNS, IPsec, and TLS.
  • Experience with infrastructure-as-code (IaC) tools such as Terraform, CloudFormation, or Deployment Manager
  • Strong proficiency in CI/CD tools such as GitLab CI/CD;
  • Experience with containerization and orchestration tools like Docker and Kubernetes;
  • Familiarity with container technologies (Docker, Kubernetes a plus).
  • Knowledge of cybersecurity principles and secure infrastructure practices.
  • Knowledge of Linux operating systems and networking concepts;
  • Effective communication and collaboration abilities.
Preferred Certifications
  • Microsoft Certified: Azure Administrator Associate
  • Microsoft Certified: DevOps Engineer Expert
  • Cisco CCNP or equivalent cloud-networking certifications
Benefits
  • Competitive remuneration package adjusted to proven skills and experience;
  • Excellent working conditions;
  • Exposure to training and professional development capabilities, including the ability to engage in cutting-edge research;
  • Exposure to international clients and collaborators.
