About the job

Join Our Team as a Network Software Engineer

At blaxel, we are seeking an exceptional Network Software Engineer to spearhead the architecture and development of the networking infrastructure for the world's first AI-native cloud.

In this role, you will design and implement a comprehensive virtual networking stack for Blaxel’s Virtual Private Cloud (VPC), our cutting-edge Software-Defined Networking (SDN) fabric tailored for agentic AI workloads. Your contributions will encompass ultra-high-performance dataplane technologies, including VPP, DPDK, and eBPF, alongside distributed control-plane systems and traffic services developed in Rust and Go.

You will be responsible for enhancing our globally distributed networking suite, which includes our load balancer and HTTP proxies built in Rust, traffic routing systems, and data plane components that currently handle over 1.5 million requests daily. Your objective is to develop a VPC that significantly outperforms conventional cloud solutions in terms of throughput, latency, visibility, and security.

If you are a systems-oriented engineer with a passion for Rust, Go, networking concepts, and building cloud infrastructure from the ground up, this is the perfect opportunity for you.
