Develop and present detailed High-Level Designs (HLD) and Low-Level Designs (LLD), along with implementation plans, test plans, and bills of materials for client approval.
Act as the primary technical point of contact and trusted advisor for clients, managing expectations, providing expert guidance, and ensuring project objectives are met on time and within budget.
Architect, deploy, and manage advanced network security solutions, including next-generation firewalls (NGFW), intrusion prevention systems (IPS), VPNs, and Network Access Control (NAC) platforms like Cisco ISE or Aruba ClearPass.
Plan and execute large-scale network migrations, such as data center consolidations, cloud integrations (AWS, Azure), or transitions to SD-WAN fabrics, ensuring minimal business disruption.
Serve as the highest escalation point for troubleshooting and resolving mission-critical network issues, performing in-depth root cause analysis to develop permanent solutions.
Provide expert-level guidance on dynamic routing protocols, including BGP, OSPF, and EIGRP, in complex, large-scale enterprise and service provider environments.
Design and implement highly available and resilient network infrastructures by leveraging redundancy, failover mechanisms, and robust disaster recovery strategies.
Lead client-facing workshops and discovery sessions to thoroughly understand and document business and technical requirements, translating them into scalable and future-proof network architectures.
Automate routine network provisioning, configuration, and monitoring tasks using scripting languages like Python and automation frameworks such as Ansible.
Optimize network performance and user experience through the implementation of Quality of Service (QoS) policies, traffic shaping, and leveraging advanced network monitoring and analytics tools.
Design and deploy robust enterprise wireless solutions (Wi-Fi 6/6E), conducting site surveys and spectrum analysis to ensure optimal coverage, performance, and security.
Evaluate emerging networking technologies, vendors, and industry trends to provide clients with forward-thinking recommendations and maintain a competitive advantage.
Provide strong technical leadership and mentorship to junior engineers, client IT staff, and project team members, fostering a culture of technical excellence and knowledge sharing.
Create and maintain comprehensive network documentation, including detailed network diagrams, configuration standards, and operational runbooks for seamless client hand-off.
Design and configure public cloud networking components within AWS (VPCs, Direct Connect, Transit Gateway) and Azure (VNets, ExpressRoute, Virtual WAN).
Configure and manage advanced load balancing solutions (e.g., F5 BIG-IP LTM/GTM, Citrix ADC) to ensure application availability and performance.
Lead the technical response to Requests for Proposals (RFPs) and Requests for Quotes (RFQs), developing solution narratives and effort estimations.
Interface with various technology teams, including server, storage, security, and application groups, to ensure holistic solution design and successful project delivery.

Secondary Functions

Support pre-sales activities by serving as a technical expert during client meetings and solution demonstrations.
Contribute to the development and curation of internal knowledge bases, best practice documents, and reusable design templates.
Collaborate with business development teams to create compelling proposals and detailed Statements of Work (SOWs).
Participate in industry conferences, webinars, and training to maintain an expert-level understanding of the technology landscape.
