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.

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.
