Senior Software Engineer (Remote)

About the Team

We’ve grown rapidly. Today, we are serving billions of HTTP requests and sending over 12 billion messages daily. We achieve 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 a strong competitive edge.

The Core Services team enables product development by designing, developing, and operating cross-cutting horizontal services—the backbone of our technical stack. This includes a high-volume delivery pipeline sending billions of push notifications, SMS, and emails every day; gRPC services in Go and Rust; and Kafka consumers written in Rust. Our technology ecosystem includes Rust, Go, Ruby, gRPC, Redis, Kafka, Scylla, and PostgreSQL.

As a Staff Software Engineer, you’ll have the autonomy to drive significant projects and directly influence our platform’s performance and features.
