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).

While no longer a startup - we have 250+ people on board and have been operating since 2011, we’ve kept our people-oriented culture. Our values are simple:

• Team up to win.

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 such as switches, routers, and smart network interface cards (smartNICs).

We are looking for an engineer with a background in device drivers and OS programming to develop and tailor a network operating system for our clients devices.

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.
• Most of our clients are based in the US, so work in the afternoon may sometimes be required.

Your role

As a part of the team, your responsibility will be to:

• Research and define how to implement client requirements and ideas best.
• Take part in technical discussions with the team and the client.
• Develop software using mainly C/C++, but other programming languages such as Python or Go may be used occasionally.
• Create unit tests for your code, conduct code reviews, create documentation, and take part in other activities related to software development.
• Fix bugs efficiently and effectively and find workarounds for blockers.
• Occasionally, take part in technical pre-sales meetings.

Do we have a match?

As a Software Engineer with C and Linux Device Drivers, you must meet most of the following criteria:

• Proficiency in C programming language.
• Experience with other programming languages (C++, Go, Python).
• 2+ years of experience in Linux device driver programming (e.g., device driver model, platform, Multi-Function Devices - MFD, Auxiliary Bus, PCI, I2C, SPI, GPIO, LED drivers, device tree, ACPI).
• Good knowledge of git (submodules, subtrees, merging, rebasing) in large code bases.
• Build system knowledge (kbuild, make).
• Network knowledge (L3/L2/L1 ethernet).
• English at least B2 level, C1/C2 preferred.

Beyond the criteria above, we would appreciate the nice-to-haves:

• Experience with SONiC /yocto/buildroot.
• System and Service Manager knowledge (systemd, supervisord).
• Virtualization knowledge (docker containers).
• Experience with networking devices (switches, routers).
• Experience in working with Software Houses.

More reasons to join us

• Flexible working hours and approach to work: fully remotely, in the office or hybrid.
