As a DevOps engineer at Aircall, you’ll be interacting day by day with 30+ talented people in the tech team highly motivated, skilled and passionate by what they do.

DevOps architecture vision

• Our vision this year is to leverage fully decoupled architectures and ultimately microservices at scale with a reliable, event-driven, auto-healing infrastructure behind the scenes.

• We also need to track and identify activities to take actions in real-time. It can be about raising alerts, switching to a dedicated feature, routing to different providers.

• To ensure that, we plan to create a very rich and secure data lake with AWS S3, Kinesis, DynamoDB, Lambda, Athena, and other cool serveless stuff. You’ll be part of this challenging but sexy project !

“Every things fails all the time”, we want to embrace that thought and be prepared for when it arrives with performance testing and regular chaos engineering. Think about graceful degradation.
