Senior Software Engineer, Software Defined Networking
About this role
At Verda, we're building a full-stack AI cloud, covering everything from data centers and hardware to our own cloud platform that the world's leading AI teams use to do serious AI work.
We strive to make a positive mark on the world through the infrastructure we build and give leading teams a service they can truly depend on. Headquartered in Helsinki, we operate globally with offices in London and San Francisco.
Join Verda while it's still being built - not once it's finished.
About the role
Verda builds and operates its own SDN stack. Both the control plane and the dataplane are developed in house by a dedicated team. As the platform grows, so does what customers expect from it, and this role exists to turn our networking layer into a complete set of products: private networks, load balancing, and firewalls that hold up under real traffic. The job spans both halves of the stack. You'll work in C on the dataplane and in Go on the distributed control plane that drives it. We're looking for someone who enjoys low level work and chasing performance, and who's fine picking up the parts they haven't done before.
Your responsibilitiesDesign and implement networking features end to end, from the packet path through to the API customers call.
Build and extend the dataplane, working close to the hardware.
Own control plane design in Go: how network state is stored, reconciled, and applied across the fleet without a window where a tenant's traffic ends up somewhere it shouldn't.
Take features from working prototype to product, with limits, quotas, and customer documentation.
Keep an eye on performance. Our customers run demanding workloads and notice small regressions.
Debug problems that run from hardware up through the control plane, often with a customer waiting.
Own the operational side: metrics, alerting, upgrades, rollback.
Work with neighboring teams on hardware specs and network design.
