The successful candidate will remotely access the customer's Legacy Infinera DNA Network Management System (NMS) to extract network inventory, service and traffic data, analyse optical network performance, develop migration strategies and Method of Procedure (MoP) documentation, and support the execution of live migrations during planned maintenance windows. This is a hands-on engineering role requiring strong technical expertise in optical transport networks, Infinera platforms and live service migration. Responsibilities Network Discovery & Analysis Access and interrogate the Legacy Infinera DNA Platform to extract network inventory, configurations and service information. Perform traffic profiling, service utilisation analysis and dependency mapping. Analyse optical network topology, wavelengths, circuits and fibre paths. Identify migration constraints, critical services and migration risks. Produce technical discovery reports and migration assessments. Migration Planning Develop migration strategies and implementation plans for live production networks. Produce detailed Method of Procedure (MoP) documentation, including rollback plans. Use traffic profiling and dependency analysis to sequence migration waves and minimise customer impact. Support migration readiness reviews with customers and project teams. Migration Delivery Execute remote migration activities during planned maintenance windows. Perform pre-change validation and post-migration service testing. Troubleshoot technical issues and support rollback where required. Produce migration completion and acceptance documentation. ## Related Videos - [A Developer's Framework for Any Tool Migration](https://www.wearedevelopers.com/videos/2035-a-developer-s-framework-for-any-tool-migration) - [Solving Architectural Entropy With Runnable Diagrams](https://www.wearedevelopers.com/videos/100144-solving-architectural-entropy-with-runnable-diagrams) - [Navigating the AI Wave in DevOps](https://www.wearedevelopers.com/videos/853-navigating-the-ai-wave-in-devops) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [AWS Migration within 3 months](https://www.wearedevelopers.com/videos/196-aws-migration-within-3-months) - [Exploring the Potential of Decentraland](https://www.wearedevelopers.com/videos/583-exploring-the-potential-of-decentraland) ## Related Articles - [5 Reasons Why Attending Conferences in 2026 Matters More Than You Think](https://www.wearedevelopers.com/magazine/692-5-reasons-why-attending-conferences-in-2026-matters-more-than-you-think) - [How to land a developer job in Amsterdam](https://www.wearedevelopers.com/magazine/36-how-to-land-a-developer-job-in-amsterdam) - [Finding Jobs in Germany](https://www.wearedevelopers.com/magazine/375-finding-jobs-in-germany) - [The Best Job Search Websites of 2025](https://www.wearedevelopers.com/magazine/368-the-best-job-search-websites-of-2025) - [Mastering Remote Work: Tips for Developers](https://www.wearedevelopers.com/magazine/558-mastering-remote-work-tips-for-developers) - [A Guide to Green Tech and Green IT Careers](https://www.wearedevelopers.com/magazine/374-a-guide-to-green-tech-and-green-it-careers)
