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).\n While no longer a startup - we have 250 people on board and have been operating since 2011 weve kept our people-oriented culture. Our values are simple:\nAct to deliver.\nDisrupt to grow.\nTeam up to win.\nThe project and the teamThe 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.\nThe project involves close collaboration with a team from our client (a global leader in networking) where 3 engineers are already engaged. On our side were building a team of mid and senior-level engineers who will take ownership of implementing new features and ensuring compliance with optical networking standards.\nWhat else you should know:\nWork is highly technical requiring a solid understanding of optical transceiver specifications diagnostic interfaces and low-level C development\nYoull work directly with specifications (SFF/SFP) and translate them into production-quality code\nYoull collaborate closely with experts on both the client and CodiLime side exchanging knowledge and driving innovation\nWe 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.\nYour roleAs a part of the project team you will be responsible for:\nImplementing networking features for fiber-optic networks in C\nWorking with SFF/SFP specifications and translating them into working code\nProgramming in user space developing logic on top of existing kernel drivers\nCollaborating with client-side engineers and other team members to deliver reliable standards-compliant implementations\nReading analyzing and applying industry specifications and technical documentation to real-world implementations\nDo we have a matchAs a Software Engineer you must meet the following criteria:\nStrong knowledge of C programming\nExperience in networking ideally with optical networking (fiber SFF SFP standards)\nAbility to interpret and implement technical documentation/specifications (e.g. SFF committee specs)\nExperience with user-space development and implementing logic on top of kernel drivers\nGood command of English (B2 level or higher)\nBeyond the criteria above we would appreciate the nice-to-haves:\nKnowledge of specific SFF standards (e.g. SFF-8472 SFF-8431 SFF-8024)\nExperience working with optical transceivers diagnostic monitoring interfaces or vendor-specific firmware\nFamiliarity with large networking environments and device ecosystems\nPrevious experience in a collaborative setup with cross-company teams\n\nMore reasons to join usFlexible working hours and approach to work: fully remotely in the office or hybrid\nProfessional growth supported by internal training sessions and a training budget\nSolid onboarding with a hands-on approach to give you an easy start\nA great atmosphere among professionals who are passionate about their work\nThe ability to change the project you work
