Network Designer

As a Network Designer, you will bridge the gap between business objectives and technical execution. This role demands deep technical expertise across routing, switching, WAN, and modern network architectures. You will take ownership of the end-to-end design lifecycle—producing both High-Level Designs (HLD) and Low-Level Designs (LLD), evaluating emerging technologies, and providing technical leadership on complex network transformation projects. This is an exceptional opportunity for a self-driven engineer looking to make a measurable impact on a large-scale enterprise network.

Advantages
Strategic Influence: Shape and modernize the long-term network strategy for a complex, large-scale enterprise environment.

Professional Growth: Act as a trusted technical advisor, balancing deep technical execution with high-level business priorities.

Collaborative Culture: Thrive within a forward-thinking engineering team that prioritizes standardized, optimized, and low-complexity designs.

Innovation-Driven: Gain exposure to next-generation networking trends, including SDN, intent-based networking, and cloud-connected ecosystems.

Responsibilities
1. Network Design & Architecture
Design and develop scalable, resilient network solutions across LAN, WAN, and Data Center environments.

Produce comprehensive High-Level Design (HLD) and Low-Level Design (LLD) documentation with explicit, actionable implementation guidance.

Evaluate and recommend cutting-edge network technologies, hardware platforms, and strategic vendors.

Ensure all technical designs strictly align with enterprise architecture standards and corporate security policies.

2. Project Delivery & Technical Leadership
Partner with project managers, cross-functional stakeholders, and operations teams to deliver seamless network solutions.

Lead or contribute heavily to the end-to-end design lifecycle, from initial requirements gathering to operational handoff.

Provide technical leadership and mentorship on complex initiatives and large-scale network transformation projects.

3. Security, Optimization & Standards
Integrate secure design principles into every architecture layer (e.g., Network Segmentation, Zero Trust, and Access Control).

Support capacity planning, network performance analysis, and identify opportunities to optimize reliability and cost efficiency.

Collaborate with operations teams to troubleshoot high-level escalated network issues when required.

Maintain accurate, up-to-date network diagrams, technical documentation templates, and design guidelines.

Qualifications
Required Experience
Industry Tenure: 5+ years of dedicated experience in network design, engineering, or enterprise architecture.

Scale: Proven track record designing enterprise-scale networks within multi-site, hybrid, or cloud-connected environments.

Education: Bachelor’s degree in Electrical Engineering, Computer Science, Information Technology, or equivalent professional experience.

Technical Skills Matrix
Routing Protocols: Strong, authoritative knowledge of BGP, OSPF, and EIGRP.

Layer 2/3 Technologies: Deep understanding of VLANs, STP, VXLAN, and MPLS.

WAN Engineering: Practical experience with IPSec, SD-WAN, and Internet-based VPNs.

Data Center Architecture: Familiarity with modern data center setups, including spine-leaf and fabric-based networking.

Security & Cloud: Hands-on or design-level exposure to firewalls, Network Access Control (NAC), and cloud environments (AWS or Azure).

Automation (Asset): Familiarity with scripting and automation tools such as Python and Ansible.

Preferred Certifications
CCNP / CCIE (Enterprise or equivalent vendor certification).

Explicit certification or deep architecture experience in SD-WAN platforms.

Nice-to-Have
Experience with Software-Defined Networking (SDN) and intent-based networking.

Practical exposure to network observability and advanced telemetry platforms.
