What you'll have here:
  • In-house products: Working on products that we use every day and have millions of users. Some of them are your friends, neighbors, family members. We are our own clients. Our opinions and experiences are directly shaping the products that we design and create. 
  • People: You will work with experts, community leaders and senior engineers who made these products from scratch. They will reveal to you how the whiteboard idea turns into a worldwide platform. 
  • Internal learning sessions and innovation challenges: We are an innovation center primarily and you can be part of initiatives, research and focus groups… and don’t miss to take a place in innovation challenges and hackathons. 
  • Engineering mindset: We are engineering our solutions from ground up using open-source tools and customizing them to our needs. We worry about performance, we analyze and observe our system. We are not throwing money at the problem, we actually care if things could be more optimal. 
  • Career growth: We strongly believe in feedback culture and development plans. 
  • Community: You wanna share your knowledge with the community? We are organize meetups and internal workshops. You are more than welcome to participate. If you are not a great speaker, that is also fine. 
Your Responsibilities:
  • Define technical requirements for GPON and XGS-PON home gateways, ensuring functionality, performance, and interoperability with OLT ecosystems and adherence to ITU-T standards. 
  • Collaborate with software engineers to develop in-house Open Source OS-based home gateways supporting advanced features and third-party applications, helping them with domain-specific tasks and challenges. 
  • Set up, test, and validate PON provisioning and configuration workflows using ACS systems (TR-069, TR-369) and maintain a cutting-edge UC lab test environment with necessary infrastructure and tools. 
  • Troubleshoot and resolve issues across the PON network, including OLT configurations, ACS communication, and gateway interoperability. 
  • Support product managers by providing technical input for product definition and aligning with industry standards and best practices. 
  • Document requirements, workflows, testing procedures, and interoperability cases while promoting best practices in network operations and access development 
What we're looking for:
  • PON Technology Expertise: In-depth knowledge of GPON, XGS-PON, NG-PON2 (ITU-T G.984/G.987) with hands-on experience in OLT/ONT configurations. 
  • Provisioning and ACS Systems: Proficient in managing multi-vendor environments with ACS platforms (TR-069, TR-369) for provisioning and device management. 
  • Testing and Validation: Experienced with tools like CD Router and setting up lab environments for performance and interoperability testing. 
  • Troubleshooting: Skilled in diagnosing and resolving issues across gateways, OLTs, and ACS systems. 
  • Collaboration: Strong ability to work cross-functionally and share domain knowledge to align team efforts. 
  • Network Operations: Knowledgeable in implementing best practices for network operations, adhering to industry standards and trends. 
  • Fiber Optics Fundamentals: Solid understanding of signal propagation, attenuation, dispersion, and optical network design. 
  • Documentation: Skilled in documenting requirements, test procedures and scenarios, and configurations to ensure standards compliance. 
  • Solid problem-solving skills with a proactive approach to challenges. 
  • Strong communication skills and ability to work in a team-oriented environment.
