Gerakas, Greece

Upstream is leading the mobile internet revolution in high growth markets. Our pioneering platform provides 1.2 billion people with affordable and secure access to digital services.

In 2017 alone, we enabled over 100 million users to make digital purchases worth more than $210 million.

Our focus centers on streamlining the development, building, testing, integration, packaging, and deployment of our micro-services. We are seeking for a DevOps Engineer to help us maintain and scale our infrastructure in order to offer our users an even greater experience.

An ideal candidate would be a passionate engineer who loves Linux, who feels more comfortable in the shell rather than in an IDE, who is intimately familiar with cloud infrastructure.

  • Trouble-shoot and classify production issues
  • Support the capacity planning for new projects in terms of hardware requirements, using proven best practices.
  • Monitor and tune production systems performance
  • Develop command line tools that enable developers to quickly build, bake, and deploy images locally and to the cloud
  • Work directly with Upstream engineers to provide a polyglot-friendly experience and first-class support for platforms built on Java, Python, php and others


  • Great communication skills, both written and verbal.
  • Linux experience -- deep knowledge of Linux system administration
  • Cloud experience -- designing and building tools and infrastructure for cloud platforms (e.g. AWS)
  • Programming experience -- Go, shell, Python, Java amongst others
  • Operational experience -- comfortable providing support to other departments, optimizing deployments for availability and uptime, going deep on troubleshooting and remediation
  • Exposure to container technology (e.g. Docker), container-focused Linux distributions, and virtualization in the cloud
  • Good knowledge of Relational Databases (e.g. postgres), NoSQL DBs/systems (e.g. Redis, ElasticSearch)
