Why BT? 

BT Group was the world’s first telco and our heritage in the sector is unrivalled.  As home to several of the UK’s most recognised and cherished brands – BT, EE, Openreach and Plusnet, we have always played a critical role in creating the future, and we have reached an inflection point in the transformation of our business.  

Over the next two years, we will complete the UK’s largest and most successful digital infrastructure project – connecting more than 25 million premises to full fibre broadband.  Together with our heavy investment in 5G, we play a central role in revolutionising how people connect with each other.  

 While we are through the most capital-intensive phase of our fibre investment, meaning we can reward our shareholders for their commitment and patience, we are absolutely focused on how we organise ourselves in the best way to serve our customers in the years to come.  This includes radical simplification of systems, structures, and processes on a huge scale. Together with our application of AI and technology, we are on a path to creating the UK’s best telco, reimagining the customer experience and relationship with one of this country’s biggest infrastructure companies.   

Change on the scale we will all experience in the coming years is unprecedented.  BT Group is committed to being the driving force behind improving connectivity for millions and there has never been a more exciting time to join a company and leadership team with the skills, experience, creativity, and passion to take this company into a new era.

• Experience working with large datasets and performing quantitative analysis  
• Ability to interpret technical data and translate it into planning recommendations  
• Strong attention to detail and structured problem-solving skills  

What you’ll be doing – your accountabilities 

• Assist with IP and optical network capacity planning, including traffic growth analysis and demand forecasting  
• Analyze utilization, throughput, latency, and error metrics from network elements and links  
• Build and maintain Excel-based planning models, including pivot tables, formulas, macros, and charts  
• Support the development and maintenance of network topology models, including routers, links, and optical paths  
• Assist in evaluating network expansion scenarios, upgrade options, and cost/performance trade-offs  
• Support planning activities related to router port utilization, interface capacity, and optics selection  
• Document planning assumptions, network designs, and engineering recommendations  
• Collaborate with network engineering, operations, and architecture teams to validate data and planning outputs  
• Support ad-hoc technical analysis and reporting requests  

Leadership accountabilities 

Communication and Stakeholder Engagement 

• Maintain open and transparent communication with all stakeholders. 
• Act as a liaison between departments, ensuring alignment and fostering positive relationships. 

Vision and Strategy 

• Clearly articulate project objectives and the broader vision for efficiency improvements. 
• Align project plans and efficiency initiatives with organisational goals and priorities. 

Decision-Making

• Basic understanding of optical networking, including:  
• Fiber types and basic optical link concepts  
• DWDM systems and transceivers (e.g., SFP+, QSFP+)  
• Familiarity with network diagrams, logical and physical topology representations  
• Exposure to planning, monitoring, or inventory tools  
• Experience with additional analysis tools such as Power BI, SQL, or Python  
• Understanding of network growth modeling and capacity thresholds  
• Familiarity with Microsoft Copilot (or similar AI tools) to help draft summaries, improve written communication, and speed up everyday tasks  
• Comfort using AI tools responsibly (e.g., avoiding sensitive data and double-checking accuracy)  

Key decisions 

•   Capacity planning and upgrade recommendations 
  Make recommendations on when and where to add capacity based on traffic growth forecasts, utilisation trends, and performance data. 
•  Network expansion and design options 
  Assess and recommend preferred network expansion scenarios and upgrade paths, balancing cost, performance, and scalability. 
•   Data quality and modelling assumptions 
  Determine planning assumptions, validate data sources, and decide acceptable thresholds for use in forecasting and modelling. 
•  Prioritisation of planning activities 
  Prioritise analysis, modelling, and planning work based on business demand, risk levels, and stakeholder requirements. 
•   Technology and equipment selection (supporting) 
  Contribute to decisions on router port utilisation, interface capacity, and optics selection based on technical and commercial considerations. 
•  Risk identification and mitigation 
  Identify risks related to capacity shortfalls, performance degradation, or design limitations and recommend mitigation actions. 
•  Trade-offs between cost and performance 
  Evaluate and recommend decisions where trade-offs are required between investment cost, service quality, and future scalability. 
• Planning outputs and recommendations 
  Decide the appropriate level of detail and confidence in planning outputs before presenting to engineering, architecture, or delivery teams. 
• Stakeholder alignment and challenge 
  Decide when to challenge data, assumptions, or requirements from stakeholders to ensure robust planning outcomes. 
• Process and tool improvements 
  Identify and decide opportunities to improve planning processes, data handling, and modelling approaches to increase efficiency and accuracy.
