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

The goal of the project is to develop and extend networking functions in optical networks (fiber optics) with a strong focus on SFF/SFP standards (e.g., SFF-8472, SFF-8431). Engineers will implement new features in user space, building on top of existing drivers, strictly following detailed technical specifications.

The project involves close collaboration with a team from our client (a global leader in networking), where 3 engineers are already engaged. On our side, we’re building a team of mid and senior-level engineers who will take ownership of implementing new features and ensuring compliance with optical networking standards.

What else you should know:

Work is highly technical, requiring a solid understanding of optical transceiver specifications, diagnostic interfaces, and low-level C development
You’ll work directly with specifications (SFF/SFP) and translate them into production-quality code
You’ll collaborate closely with experts on both the client and CodiLime side, exchanging knowledge and driving innovation

We work on multiple interesting projects at the time, so we may invite you to the interview for another project if we see that your competencies and profile are well suited for it.

Your role

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

Implementing networking features for fiber-optic networks in C
Working with SFF/SFP specifications and translating them into working code
Programming in user space, developing logic on top of existing kernel drivers
Collaborating with client-side engineers and other team members to deliver reliable, standards-compliant implementations
Reading, analyzing, and applying industry specifications and technical documentation to real-world implementations

Do we have a match?

As a Software Engineer, you must meet the following criteria:

Strong knowledge of C programming
Experience in networking, ideally with optical networking (fiber, SFF, SFP standards)
Ability to interpret and implement technical documentation/specifications (e.g., SFF committee specs)
Experience with user-space development and implementing logic on top of kernel drivers
Good command of English (B2 level or higher)

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

Knowledge of specific SFF standards (e.g., SFF-8472, SFF-8431, SFF-8024)
Experience working with optical transceivers, diagnostic monitoring interfaces, or vendor-specific firmware
Familiarity with large networking environments and device ecosystems
Previous experience in a collaborative setup with cross-company teams
