About the role

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:

Act to deliver.

Disrupt to grow.

Team up to win.

The project and the team
We develop software for modern networking platforms and operating systems for leading equipment manufacturers, as well as various other cloud-native, containerized services and solutions. In our test engineering teams, we bridge the gap between complex physical hardware (advanced routers, NPUs) and high-velocity, AI-driven development
We are looking for an engineer who combines solid networking hardware intuition with an AI-first mindset to rapidly build, test, and maintain a Python testing tool across diverse router platforms. You don't need to write low-level code from scratch—your super-power is leveraging LLMs to code fast, flash hardware, and validate your code efficiently.
What else you should know:

We work using client-supplied hardware and tools

The project is managed by the client, but the Codilime manager is also involved

The client is from the US, so early evening meetings may be required

Your role
As a part of the project team, you will be responsible for:

Develop and debug Board Support Package (BSP) and low-level software for high-performance networking devices

Research and define how to implement client requirements and ideas best

Engage directly with client architects and end-users through design calls and syncs to gather requirements, clarify edge cases, and shape the future of the testing tool,

Use modern AI coding tools (LLMs, Copilot, Codex, etc.) as your primary workflow to rapidly generate, refactor, and expand test scripts

Do we have a match?
As a Network Software Engineer you must meet the following criteria:

Strong proficiency in C and Linux system/kernel programming, plus Python scripting skills.

Hands-on experience with agentic AI.

Experience with general hardware integration and bring-up.

Experience with networking hardware in at least one area, such as:

high-speed transceivers, network interfaces, and related industry standards.

integrating and configuring ASICs, NPUs, or specialized switching silicon using vendor SDKs.

Additionally:

Background in register-level programming and communication protocols such as I2C, PCIe, SPI, and MDIO.

Familiarity with network encryption protocols at the hardware/datapath level would be a plus.

More reasons to join us

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

Professional growth supported by internal training sessions and a training budget

Solid onboarding with a hands-on approach to give you an easy start

A great atmosphere among professionals who are passionate about their work

The ability to change the project you work on
