Role Overview

The Network Engineering Professional supports the design, modeling, and optimization of IP and optical transport networks. This role focuses on data-driven capacity planning, network performance analysis, and topology documentation. The ideal candidate has strong Excel and analytical skills combined with foundational knowledge of routing, network architecture, and optical systems, and is eager to grow into a more advanced network planning or engineering role.

Key Responsibilities

• 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

Required Technical Skills & Qualifications

• Bachelor’s degree in Telecommunications, Networking, Electrical Engineering, Computer Science, or related field
• Strong proficiency in Microsoft Excel for technical analysis (formulas, pivot tables, charts, data validation)
• Solid understanding of IP networking fundamentals, including:
• Layer 2 / Layer 3 concepts
• Routing and switching principles
• Basic routing protocols (e.g., OSPF, BGP – conceptual level)
• 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
• Fluent English is mandatory, as the entire recruitment process will be conducted in English.

Preferred / Nice-to-Have Technical Skills

• Introductory knowledge of router hardware, line cards, interfaces, and port speeds (1G/10G/100G+)
• 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)

Career Development

This role provides a strong foundation in network planning, capacity engineering, and data-driven decision-making, with clear pathways into senior network planning, network engineering, or network architecture roles
