Athens, Attica, Greece Paymentology Full time €60,000 - €120,000 per year

At Paymentology, we're redefining what's possible in the payments space. As the first truly global issuer-processor, we give banks and fintechs the technology and talent to launch and manage Mastercard and Visa cards at scale—across more than 60 countries.

Our advanced, multi-cloud platform delivers real-time data, unmatched scalability, and the flexibility of shared or dedicated processing instances. It's this global reach and innovation that sets us apart.

We're looking for a Cloud Network Engineer to design, implement, and govern Paymentology's global cloud network infrastructure. This role ensures the security, performance, and compliance of network environments across AWS, GCP, and OCI—powering the connectivity backbone for critical platforms such as PayHub and BL3.0. It blends deep technical expertise in networking, firewall administration, and Infrastructure as Code (IaC) to advance our cloud strategy.

What you get to do:
  • Architect and manage AWS cloud network infrastructure including VPCs, subnets, Transit Gateways, Direct Connect, VPNs, and PrivateLink.
  • Configure and maintain Palo Alto firewalls and Panorama, optimising security policies and integrating with hybrid cloud environments.
  • Develop, modularise, and govern Terraform-based IaC for multi-cloud networking infrastructure, ensuring secure, scalable, and repeatable deployments.
  • Implement AWS WAF, API Gateway, and Auth0/Authorizer configurations to secure and validate API access and traffic flow.
  • Collaborate with Platform, Security, and Cloud teams to align on network policies, compliance (e.g., PCI DSS), and operational reliability.
  • Maintain IAM, SCPs, and role-based access controls across multi-account AWS structures in line with governance frameworks.
  • Lead network incident troubleshooting, root cause analysis, and performance optimisation, ensuring uptime across regions.
  • Maintain Confluence documentation and operational runbooks for cloud networking, firewall configurations, and CI/CD pipelines.
Requirements

What it takes to succeed:

  • 7+ years in cloud infrastructure or networking roles with deep AWS experience.
  • Expert in AWS networking components: TGW, VPC, VPN, Direct Connect, Route 53, ALB/NLB.
  • Hands-on Palo Alto firewall administration and Panorama configuration.
  • Advanced Terraform usage, including module reuse, provider aliases, and IaC governance.
  • Proficiency in Python, Go, or Java for scripting and API integrations.
  • Familiarity with compliance frameworks (PCI DSS, ISO and secure cloud networking.
  • Bonus: AWS Advanced Networking Certification, experience with GCP or OCI.
What you can look forward to:

At Paymentology, it's not just about building great payment technology, it's about building a company where people feel they belong and their work matters. You'll be part of a diverse, global team that's genuinely committed to making a positive impact through what we do. Whether you're working across time zones or getting involved in initiatives that support local communities, you'll find real purpose in your work—and the freedom to grow in a supportive, forward-thinking environment.
