Job Objective:

The IP Network Planner is responsible for designing, planning, documenting and optimizing IP networks across core, aggregation and access domains. The role ensures scalable, resilient and high‑performance network infrastructure by producing high‑quality architectural designs (HLDs/LLDs), forecasting capacity, maintaining accurate network records and guiding end‑to‑end implementation in collaboration with cross‑functional engineering teams.

Reporting Line: Principal IP Architect

Key Duties and Responsibilities

IP Network Design and Architecture

• Plan, design and optimize IP/MPLS networks across core, edge, aggregation, and data‑center environments
• Develop resilient routing architectures including BGP, IS‑IS/OSPF, MPLS L2/L3 services, Internet transit and peering strategies
• Produce architectural deliverables such as capacity models, traffic‑engineering approaches, redundancy frameworks and service‑specific infrastructure blueprints

 High‑Level and Low‑Level Design Documentation (HLD/LLD)

• Create comprehensive High‑Level Designs (HLDs) describing architectural intent, technology selection, network topology, inter‑domain integration, performance assumptions and scalability plans
• Develop detailed Low‑Level Designs (LLDs) including IP addressing plans, interface‑level specifications, routing policies, protocol configurations, traffic‑engineering parameters and implementation workflows
• Ensure all design documentation adheres to internal engineering standards, quality controls and compliance requirements

Implementation Oversight and Delivery Assurance

• Oversee the full implementation lifecycle of IP network solutions
• Collaborate with Field Engineering, Network Operations, NOC, PMO and suppliers to validate deployments
• Conduct design sign‑off, engineering governance and post‑implementation verification
• Ensure implementation updates are reflected in planning systems and network inventory platforms

Capacity, Resource and Inventory Planning

• Forecast IP network capacity needs across routing, switching, traffic flows and peering/transit services
• Conduct audits on IP network utilization and resource allocation
• Maintain accurate network inventory including addressing schemes, interfaces, ports, configurations

Documentation, Compliance and Governance

• Maintain updated technical documentation including diagrams, routing policies, service delivery models
• Help refine company network planning standards, policies and procedures
• Ensure designs comply with security, operational and regulatory standards

Cross‑Functional Collaboration

• Work with Project Managers, Operations, Field Engineering and Network Architects.
• Support departments in alignment with organization planning responsibilities

Technical Analysis and Optimization

• Conduct network performance assessments
• Recommend improvements for scalability, efficiency and modernization
• Support troubleshooting escalations related to design concerns

Reporting and Stakeholder Management

• Prepare technical reports, capacity analyses and planning assessments
• Support budget planning, vendor evaluation and contract/PO management activities

Minimum Qualifications 

• Bachelor’s degree in Engineering, Telecommunications, Computer Engineering or equivalent
• Master’s degree is an advantage

Experience and Skills

• Strong proficiency in IP networking technologies
• Experience producing professional HLDs and LLDs
• Strong understanding of capacity planning and traffic engineering
• Experience with NMS/EMS/OSS/BSS tools and automation
• Strong documentation and analytical skills
• Ability to guide engineering teams during implementation

Competencies 

• Client focused, relationship builder
• Integrity, honest with high ethical standards
• Boundless, passionate and flexible
• Personal excellence, accuracy and attention to detail
