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 Engineer to strengthen Paymentology’s cloud infrastructure foundations, with a strong focus on AWS multi-account governance, IAM security controls, and Infrastructure as Code automation.

What you get to do::

• Support and enhance Paymentology’s AWS cloud foundation, including multi-account governance using AWS Organizations, Landing Zone frameworks, and Service Control Policy guardrails.
• Design, implement, and maintain secure IAM roles, policies, and access controls aligned with least privilege and compliance requirements.
• Develop, modularize, and govern Terraform-based Infrastructure as Code to enable scalable, repeatable, and secure infrastructure deployments.
• Integrate infrastructure automation into CI/CD pipelines to ensure consistency across development, testing, and production environments.
• Implement and support core AWS infrastructure services such as API Gateway, Lambda, CloudFront, Route 53, and application and network load balancers.
• Collaborate closely with Platform Engineering and Security teams to align infrastructure standards, governance controls, and operational reliability.
• Support troubleshooting, incident response, and root cause analysis across cloud environments to maintain high availability and performance.
• Maintain clear Confluence documentation, operational runbooks, and infrastructure standards to support long-term platform sustainability.

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.
