We're looking for a Cloud Network Engineer to design, implement, and govern Paymentology's global cloud network infrastructure.

  • 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.
