Get to know us better

CodiLime is a software and network engineering industry expert and the first-choice service partner for top global networking hardware providers, software providers and telecoms. We create proofs-of-concept, help our clients build new products, nurture existing ones and provide services in production environments. Our clients include both tech startups and big players in various industries and geographic locations (US, Japan, Israel, Europe).

The project and the team

We develop modern Software-defined Networking (SDNs) and network operating systems for leading networking equipment manufacturers. We work with cloud-native, containerized software and services, as well as with user-space and kernel-space drivers for advanced network equipment, including switches, routers, and smart network interface cards (smartNICs).

We are looking for an engineer with a background in device drivers, hardware offloading, and OS programming for an innovative project aiming at offloading a firewall to a hardware device.

What else you should know:

• We often work using client-supplied hardware and tools
• Our projects may be managed by our EMs or directly by the client
