DevOps – Site Reliability Engineer (SRE)

Because Antidot operates its own SaaS solutions, we are strong believers in the DevOps and Continuous Delivery strategies. Our Site Reliability Engineers (SRE) develop and operate software that automate system admin tasks.


  • Within an agile team, you contribute to developing the infrastructure that is used to operate Antidot’s software solutions, and to keeping it up-and-running.
  • You share Antidot’s philosophy that anything that can be automated, should be automated. You use state of the art technologies for software development, configuration management, and deployment. You are curious, continuously looking at new technologies, and not afraid to make suggestions.
  • You provide to developers all the information they need to understand how to use the infrastructure. You work closely with product engineering teams to improve the operability of solutions.


  • Do everything you can to have nothing to do! If needed, spend 3x more time but make sure you won’t have to do it again.
  • Automate everything, monitor everything and do “truly” continuous deployment.
  • Develop infrastructure software with the same tools, the same methods, the same quality and testing than our solutions.
  • Always question what you know, try new solutions, look at what is happening in the open source world and don’t hesitate to contribute.


  • Rigorous and efficient: working under pressure and deadline does not scare you.
  • Flexible and open-minded: you have no prejudice, you always look for the best solution, the best language, the best tool for each problem.
  • Passionate: about your work, about new open source technologies. You wouldn’t mind going to Fosdem.
  • Collaborative: you love to work in a team, you love to learn, share, review and even challenge each other’s code.
