Job Description Role Overview The Staff Network Engineer is a senior individual contributor responsible for the technical direction, architecture guidance, design governance, implementation oversight, and operational support of enterprise WAN, LAN, wireless, and secure-connectivity solutions within a corporate network environment. This role provides technical leadership for the organization’s highest-complexity and enterprise-scale network initiatives. The Staff Network Engineer influences architecture, reference patterns, engineering standards, and technology roadmaps; provides end-to-end technical oversight across engineering, security, project, operations, and vendor teams; and serves as a senior escalation point for complex cross-domain issues. The Staff Network Engineer operates with a high degree of autonomy and uses technical influence, mentoring, and engineering leadership to improve network reliability, security, scalability, operational supportability, and long-term technology outcomes. Key Responsibilities Network Design & Implementation * Provide technical direction for enterprise WAN, LAN, wireless, remote-access, and secure-connectivity solutions. * Lead the design and technical delivery of the organization’s most complex, high-risk, or enterprise-scale network initiatives from requirements and architecture through implementation and operational acceptance. * Influence and develop network architecture principles, reference patterns, design standards, and reusable engineering practices in partnership with Architecture, Security, Operations, and other technology teams. * Produce and govern high-level and low-level network designs, technical decision records, implementation strategies, resiliency requirements, and supportability criteria. * Lead technical-design reviews and ensure solutions appropriately address reliability, scalability, capacity, security, observability, automation, and lifecycle requirements. * Assess network performance, capacity, resiliency, and technical debt and provide strategic recommendations supporting current and long-term business requirements. * Evaluate emerging network technologies and determine their potential applicability, benefits, risks, dependencies, and operational impact. * Provide technical oversight for design validation, testing, implementation readiness, rollback planning, and operational handoff. Operations & Advanced Support * Serve as a senior engineering escalation point for highly complex, cross-domain, recurring, or business-critical network incidents. * Lead root-cause analysis for significant network events and ensure corrective actions address systemic technical, process, monitoring, or supportability gaps. * Provide technical direction during major incidents and coordinate engineering analysis across internal teams, vendors, and service providers. * Establish expectations for network observability, operational readiness, troubleshooting procedures, resiliency testing, and support documentation. * Analyze incident, problem, performance, and capacity trends to identify systemic risks and prioritize engineering improvements. Security & Compliance * Provide senior technical guidance to ensure security and compliance requirements are incorporated into network architectures, standards, and major initiatives. * Lead technical analysis and remediation planning for significant network vulnerabilities, security events, and control gaps. * Evaluate proposed designs for security, resiliency, operational risk, and control effectiveness and recommend required improvements. * Promote secure-by-design practices throughout the network-engineering lifecycle. Vendor & Stakeholder Collaboration * Provide senior technical direction to vendors and service providers and evaluate proposed products, designs, implementation approaches, and corrective actions. * Provide technical leadership across Project Management, Account Management, Security, Network Operations, Enterprise Architecture, application teams, vendors, and service providers. * Communicate complex technical risks, decisions, tradeoffs, and recommendations clearly to technical and nontechnical stakeholders. Continuous Improvement & Automation * Define and advance technical practices for Python, network automation, configuration validation, testing, and operational analytics.  * Lead the development and adoption of reusable automation frameworks, engineering templates, validation controls, and standard implementation patterns.  * Develop recommendations and roadmaps addressing reliability, scalability, observability, security, technical debt, and lifecycle modernization.  * Measure whether engineering improvements deliver the intended technical and operational outcomes.  Knowledge Sharing & Mentorship * Provide technical mentorship and guidance to Network Engineers, Senior Network Engineers, and network-support engineers.  * Lead architecture reviews, design reviews, technical briefings, troubleshooting sessions, and post-incident engineering reviews.  * Create force-multiplier impact by transferring knowledge, improving engineering practices, and enabling other engineers to solve increasingly complex problems. * Provide technical leadership through influence and expertise without direct people-management responsibility. Visa requires at least 3 days in office, expectations of these days will be confirmed by your Hiring Manager. Qualifications Basic Qualification * Bachelor’s degree in engineering, computer science, information technology, or a related discipline or equivalent professional experience. * Progressive enterprise network-engineering experience, including demonstrated leadership of high-complexity or enterprise-scale network initiatives. * Expert‑level knowledge of routing protocols (BGP, OSPF). * Expert knowledge of Cisco routing and switching in large enterprise environments. * Advanced knowledge of Arista switching. * Advanced knowledge of enterprise WAN, LAN, wireless, MPLS, and TCP/IP networking. * Advanced experience with Cisco VPN networking. * Demonstrated experience developing or influencing network architectures, designs, technical standards, or reference patterns. * Experience serving as a senior technical escalation point for complex network incidents and leading systemic root-cause analysis. * Demonstrated ability to communicate complex technical decisions, risks, and recommendations to senior technical and business stakeholders. Preferred Qualification * Significant experience with SD‑WAN technologies, ideally Silver Peak. * Advanced understanding of SASE solutions. * Working knowledge of cloud networking concepts, including hybrid connectivity. * Working knowledge of Python and network automation tools. * Experience with Citrix NetScaler Access Gateways. * Experience developing reusable automation frameworks using Python, Ansible, APIs, or infrastructure-as-code practices. * Knowledge of Unified Communications and MS Teams solutions. * Cisco certification (e.g., CCNA, CCNP or equivalent experience). * Experience with network-performance, packet-analysis, configuration-management, modelling, and observability tools.
