About The Position

Tereina is an early-stage, well-funded startup supported by SAP that is building B2B payments solutions. Its platform supports cross-border payment processing, counterparty management, bank account administration, and compliance workflows for enterprise customers worldwide. The DevOps team builds and operates the cloud environments that power the platform, including build, CI/CD, development, staging, and production environments. Tereina runs Java and Spring Boot microservices on Google Kubernetes Engine, with infrastructure managed through Terraform and automated build pipelines under the reliability, security, and compliance expectations of a regulated payments business.

Reporting to the Head of Technology Operations, the Infrastructure Engineer will join the DevOps team to build and maintain infrastructure environments. The role begins with learning and maintaining the build, development, and production cloud environments, and expands to developing them as the company grows. The engineer will collaborate with development teams on infrastructure changes, improve and refactor Terraform, and expand self-service infrastructure provisioning. This role is intended for an engineer with 2–5 years of experience who wants to grow in a high-impact environment.
