About Nebius:
Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.
Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.
Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.

We're building a traffic delivery system for a variety of scenarios: IPv4 connectivity, Cloud Interconnect, Egress NAT, and a network load balancer. They serve tens of millions of packets per second.
We have a control plane microservice architecture with gRPC transport and our own Database as our data warehouse.
What we do:
- Increase service scalability

- Improve the internal architecture, optimizing interaction with related services
In this position, your responsibility will be to:

- Perform load testing for services
We expect you to have:
- Capable of writing reliable, high-performance code
- Proficient in C and ready to learn Go/C++
