About us

Zenly started in 2011 as a small team of passionate designers, engineers, and entrepreneurs gathered around the idea that frictionless location sharing is the next mobile commodity. Our R&D has brought us to release the best location sharing app in the world ;)

And now, Zenly is the mobile application that lets you instantaneously see where your friends are. We believe that making maps more social and personalised is our opportunity to improve the way people live, communicate and share moments together. Our product empowers people to find themselves, enjoy improvised moments and have fun together.

We’re looking for a Data Platform Engineer to join us at Zenly! Working from our Paris, France headquarters, you’ll play a key role in building and shaping key features that millions of Zenlyers will use every day!

Our office is big and comfortable with a fully equipped kitchen (including unlimited snacks and drinks), rest areas and sound isolation booths. Everyone at Zenly is provided with a spacious desk and top of the line computer and phone to help you build your own workspace.

We also offer a great package to all our employees including:

  • Advantageous health coverage extendable to your family
  • Public transport reimbursement
  • Weekly lunch (and regular french pastry for breakfast!)
  • Flexible time off policy
  • Handling of relocation/visa procedure


As a Data Platform Engineer, you will be responsible for architecting, implementing and releasing pieces of infrastructure on top of which the entire company relies on when it comes to publishing, consuming, storing and overall sharing data within Zenly (Backend developers, Data Scientists, Mobile developers, etc.).

Our stack is currently almost entirely written in Go, coupled with some pieces of C++ and Java for bridging with the JVM ecosystem (Hadoop & al.).

We rely heavily on Protobuf, Kafka and a whole bunch of database systems (Redis, Scylla, Elasticsearch, HDFS, PostgreSQL, etc.) which you'll have to work with on a daily basis.

Tests, genericity and monitoring will be at the very heart of your work, even more so as we try to Opensource many parts of our data platform stack.

You will work with passionate infrastructure & software engineers in order to build pieces of infrastructure that every one uses at Zenly.

You will ensure a high standard of coding, following best practices and continuous integration processes (tests, monitoring, instrumentation). Tests will be an integral part of your work, as you will be responsible for the code you produce as well as the services you deploy into production.

You enjoy digging through the internals of complex systems (databases, kernels, language runtimes, etc.) to understand how they work, and why they sometimes don't.


  • Proven experience building scalable, highly-reliable systems
  • Experience maintaining high-traffic environments (RTB, HFT, etc.)
  • An appetence for distributed-systems and related problematics
  • Experience with software engineering best practices (testing, code reviews, continuous integration, design documentation…)
  • Self-organised, proactive with ability to prioritise tasks effectively


  • Experience with Docker and Kubernetes
  • Experience with low-level programming


We are more interested in your experiences and projects, past and current, than your résumé. We'd rather hear about these and what you think you'll bring to the team. GitHub and Twitter usernames are also useful to share. All applications should be made in English.

If you already work for us, your answer will not be used against you in any way. Because a person may become disabled at any time, we are required to ask all of our employees to update their information every five years. You may voluntarily self-identify as having a disability on this form without fear of any punishment because you did not identify as having a disability earlier.
