Senior Technical Delivery Engineer – Network Infrastructure

Role Overview

The Senior Technical Delivery Engineer (Network Infrastructure) serves as the principal technical authority and hands-on lead for the architecture, implementation, and lifecycle management of enterprise network solutions. This role is responsible for driving complex client solutions across LAN, WAN, Wireless, SD-WAN, routing, switching, and application delivery/load balancing environments.

As a senior individual contributor, the role establishes network technical standards, leads end-to-end infrastructure projects from architecture to commissioning, and acts as the final technical escalation point for major incidents. Operating collaboratively alongside the Security and Systems & Storage practices, this position shares co-ownership of disaster recovery (DR) architecture at the network layer to ensure high availability, resilience, and business continuity.

Job Responsibilities

1. Network Architecture, Design & Implementation

• Solution Architecture: Lead the technical design and architecture of resilient, scalable enterprise networks across LAN, WAN, wireless, SD-WAN, and load-balancing technologies.
• Design Documentation: Produce and review comprehensive High-Level Designs (HLD), Low-Level Designs (LLD), Methods of Procedure (MOP), IP scheme architectures, and detailed topology diagrams. Validate that deployed environments align strictly with approved blueprints.
• Deployment & Integration: Configure, deploy, and validate core network components, including enterprise routers, switches, wireless controllers, load balancers, and SD-WAN devices.
• Implementation Leadership: Oversee physical and logical deployment activities, including site staging, structured cabling plans, patching schedules, and final site commissioning.
• Resilience & High Availability: Design and validate high-availability (HA) topologies, redundant transport paths, link/device failover mechanisms, and rapid routing convergence protocols.

2. Disaster Recovery & Business Continuity (Network Layer)

• DR Architecture: In partnership with the Systems & Storage team, co-design and maintain network failover architecture, disaster recovery site connectivity, and dynamic traffic redirection protocols.
• Execution & Validation: Plan and execute scheduled DR testing exercises; systematically document failover performance, latency metrics, and functional gaps.
• SLA Alignment: Validate that Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO) are consistently met at the network layer, escalating design limitations proactively where required.

3. Operations, Incident Management & Lifecycle

• Senior Escalation: Serve as the senior technical authority and highest internal escalation point (L2/L3) for major network incidents and operational outages.
• Root Cause Analysis (RCA): Conduct rigorous post-incident root cause analyses to implement permanent corrective actions and eliminate systemic failures.
• Performance & Capacity: Monitor estate health, throughput, and capacity trends across managed client environments to ensure optimal operational performance.
• Lifecycle Management: Manage software, firmware, and hardware life cycles, maintaining end-of-support (EoS) tracking and orchestrating scheduled upgrade windows.

4. Technical Leadership & Project Delivery

• Project Governance: Partner with Project Managers to scope, plan, estimate effort, and mitigate technical risks across the end-to-end project lifecycle.
• Cross-Domain Collaboration: Interface with Security and Systems & Storage pillars to deliver cohesive, cross-functional architectures subject to joint technical reviews.
• Mentorship & Quality Control: Set technical quality baselines and mentor engineering staff without carrying direct line-management administrative responsibilities.
• Vendor Management: Engagement with principal vendors and technology partners for solution validation, advanced technical escalations, and feature roadmaps.

5. Governance, Standards & Continuous Improvement

• Standardization: Define, maintain, and enforce enterprise network baseline configurations, design patterns, and Standard Operating Procedures (SOPs).
• Operational Handover: Deliver structured knowledge-transfer sessions, runbooks, and handover documentation to operational support teams prior to project sign-off.
• Process Automation: Identify opportunities to standardise designs across accounts and drive automation initiatives (e.g., scripting, configuration management) to increase operational efficiency.
• Technology Evaluation: Continuously assess emerging networking technologies to determine operational, architectural, and commercial value for managed accounts.

Job Requirements

• Education: Bachelor’s degree in Computer Science, Information Technology, Network Engineering, or equivalent practical enterprise experience.
• Experience: 5–8+ years of hands-on enterprise network engineering experience.
• Track Record: Demonstrated success leading complex, multi-site network infrastructure deployments from inception through operational handover.
• Problem-Solving: Exceptional analytical and troubleshooting skills with proven composure under operational pressure.
• Communication: Clear verbal and written articulation, with an ability to translate complex technical concepts for executive and non-technical stakeholders.
• Leadership & Influence: Ability to guide, influence, and align cross-functional technical teams without direct organizational authority.
• Accountability: Strong sense of ownership, driving tasks and projects to completion with minimal supervision.
• Maintenance Windows: Flexibility to support planned after-hours and weekend execution windows, along with periodic on-call escalation duty.
• Travel: Occasional local or regional travel to client facilities and data centres as project deliverables dictate.

Technical Proficiency

• Protocols & Routing: In-depth command of enterprise routing and switching protocols (BGP, OSPF, EIGRP, MPLS, VLANs, STP, VRRP/HSRP).
• WAN & Wireless: Hands-on experience with SD-WAN architectures, multi-path WAN optimization, site survey interpretations, RF planning, and controller-managed WLANs.
• Security & Hybrid Cloud: Solid understanding of firewall policies, IPsec/SSL VPNs, and hybrid cloud connectivity models (ExpressRoute, DirectConnect).
• Load Balancing & Automation: Working knowledge of Application Delivery Controllers (ADCs) / load balancing; familiarity with network automation tooling (Python, Ansible) and network management platforms.

Professional Certifications

• Required: Cisco CCNP Enterprise, Juniper JNCIP, Aruba ACMP, or equivalent professional-level networking credential.

• Preferred:

  • Expert-Level: CCIE or equivalent.
  • Security: Fortinet NSE 4+ or equivalent network security certification.
  • Cloud: AWS Certified Advanced Networking – Specialty, Azure Network Engineer Associate, or GCP equivalent.
