The role

Our focus centers on streamlining the development, building, testing, integration, packaging, and deployment of our micro-services. We are seeking for a Senior 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. He/She has a strong networking background, is comfortable in a polyglot environment, thrives in true-agile, fast paced, production facing environments, and may not have all the answers but surely knows how to find them.

  • Help us define the future of our artifact and container-based deployment strategies.

  • Contribute in the design of high-volume, low-latency applications for mission-critical systems, delivering high-availability and performance.
  • Trouble-shoot and classify production issues.
  • Lead 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.
  • Offer inspirational coaching and mentorship to Upstream engineers on best practices.


  • 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).

... then don’t hesitate to contact us to talk to you about this opportunity.


We offer a competitive base salary and benefits, directly dependent on the candidate’s qualifications and skills. The real excitement comes from working closely with a dynamic, smart, agile and highly motivated team in a competitive and fast paced environment.
