Software Engineer - Backend at Aircall
New York, US
Aircall is on a mission to redefine the business phone.
We are an advanced cloud-based phone system, complete business phone, and call center software — all wrapped up in one single tool.
But behind our product are the people driving it. Ambition, teamwork, transparency and community — these are the values we live by at Aircall. We know that success comes from hard work and deserves to be recognized and rewarded.
So if you’re a person that loves the challenge of a startup atmosphere, enjoys solving meaningful problems, and wants to feel like part of a family — then you just might be who we’re looking for.
At Aircall, we are looking for engaged and passionate Software Engineers to join our growing Engineering Team at NYC. Our technical challenge is to leverage a fully decoupled architecture and ultimately microservices at scale with a reliable, event-driven infrastructure behind the scenes. 
Volume: Store, aggregate and compute 1M+ events / day today, 100M+ by next year
Live: Analyze and take live decisions based on 1M+ events / day
Modularity: Make our stack scale and increase squads' productivity by featuring microservices based on event-driven architecture
Uptime: Keep a 99.99% uptime while dealing with an exponential activity growth
As a Backend Engineer, you will design, develop, deploy, operate business critical features that add customer value on top of Voice. Quality, excellence and agility drive our delivery processes and you will help us level these up. Our codebase is mainly built with Ruby, Sinatra, MySQL, Redis, and fully hosted on AWS.
About the team:
The Engineering team is composed of 40 international Software Engineers, between Paris & NYC. We are organized in Squads, working on Product features. The French team is focused on building the best phone system ever by building innovative features on our live call routing engine and ensuring a cross-channel experience from desktop to mobile.

    • You can understand and challenge front-end architecture
    • You are rigorous with code quality and other engineering best practices (testability, maintainability, design patterns)

    • You are pragmatic, data driven and you take initiatives to reach Business and Customer centric ambitious goals
