About The Team:
OneSignal has grown rapidly. Today we are serving billions of HTTP requests and sending over 12 billion messages daily. We achieved this scale by leveraging bare metal cloud and writing scale-sensitive components in languages like Rust and Go. This potent combination of high-performance, low-cost hardware with efficient resource utilization has given us an incredible competitive edge.
The Core Services team enables product development at OneSignal through the design, development, and operations of cross-cutting horizontal services which form the backbone of our technical stack.

You will work with Rust, Go, Ruby, gRPC, Redis, Kafka, Scylla, and PostgreSQL
