Backend Operations Developer (m/f/d)

Wire’s backend is hosted on Kubernetes and managed by Terraform and Helm charts. Our goal is that anyone can self-host the backend — including tricky setups like on-premise, closed network, and no AWS allowed. Your help is needed to take this to the next level and support our customers to set up their own environment!

You will be responsible for the backend’s continuous integration and deployment infrastructure, including process automation, roll-outs, and maintenance of backend services. You will work with Kubernetes, Terraform, Helm, Nix, Ansible, and upgrade these to the most recent version when available. You will deploy Cassandra and ElasticSearch clusters and keep them up-to-date. You will also talk to customers running our on-premise solution and help them to track down and solve issues when necessary. You should expect to spend 20% of your time improving our Haskell services, for instance (but not limited to) improving the interaction between services and deployment infrastructure.

Wire is transforming the way businesses communicate at the same speed that our founders disrupted telephony with Skype. Recognized by IDC, Forrester, and Gartner as one of the most secure collaboration platforms on the market, Wire offers messaging, audio/video conferencing, file-sharing, and external collaboration – all protected by the strongest end-to-end encryption. Headquartered in Berlin with offices in Switzerland and San Francisco. Our people come from a wide range of backgrounds, united by shared passion for communication, design and technology as well as privacy, security, and open source software.

Work with experts, multicultural team from 20 nationalities, competitive salary, relocation support, career growth opportunities, beautiful office with a rooftop terrace in the heart of Berlin.


Functional programming languages, adjustable standing desks, high quality chairs, regular tech talks, developer meetups in the office, bike storage, table tennis, foosball, yoga, breakfasts and lunches.
