Global migration is a 21st-century reality. Whether people are fleeing from something or racing towards better opportunity, following love or seeking new experiences, more and more are living in different environments and in new ways. We celebrate the power of people coming together. That’s why we connect ambitious people abroad with their families and friends back home so they can support each other emotionally and financially, and lead more enriched lives.

With international calling, money transfers, mobile top-up service and more we design products with the needs of modern migrants in mind.

Our ambitious team reflects our international audience. We are a diverse group of people from all over the world that come together every day—and we’re looking for others driven by the same desire to create meaningful products that bridge cultural and geographic distances.

Rebtel is looking for a Senior DevOps Engineer

About Rebtel’s infrastructure

Our infrastructure is entirely cloud-based and we have components in the 3 major cloud environments (AWS, Azure, GCP). Our infrastructure hosts our customer-facing business applications as well as support systems used internally by different teams. Given how long we have been around, we have some legacy applications and systems that run on VMs in the cloud, but our preference is for containerization orchestrated by Kubernetes.

In an environment as vast as Rebtel’s, it is important to maintain thorough documentation of our systems, but even better to persist our infrastructure as code using modern tools such as Terraform. Our work approach is well structured without being stifling. We use an agile workflow to handle day to day tasks. We strongly encourage collaboration as an excellent way to spread knowledge and to deliver universally relevant products and services.

Given our fast-paced journey and market ambition, you will find tasks that are demanding and that will trigger your creativity. At Rebtel, everyone contributes to our customer propositions - we have quick communication channels between teams and have regular hackathons to respond to opportunities and challenges as they come.

Rebtel is looking for a DevOps and Infrastructure engineer to join its team that is building new products and services in a modern, cloud-based ecosystem.
