Original job description

Job Description:

We are seeking an experienced Senior Network Engineer to design, implement, and operate our global network infrastructure across on-premises data centers and cloud environments. This role requires deep expertise in core networking technologies as well as hands-on experience with cloud networking. You'll leverage your strong understanding of routing, switching, security, and connectivity - spanning WAN/LAN, VPN, firewalls, and cloud network architecture - to ensure our environments are secure, resilient, and performant. You will also play a key role in driving and tracking the execution of complex projects and using data to guide decisions and improvements.

Responsibilities Include:

Network architecture & design: Design, build, and maintain robust, secure, and scalable network solutions across on-premises data centers and AWS cloud environments.

Core network engineering: Provide hands-on expertise across TCP/IP, routing and switching, VPN and tunneling technologies, site-to-site VPNs, and firewall installation and configuration.

Cloud networking: Configure and manage AWS network infrastructure including VPCs, VPC peering, transit gateways, CIDR block planning and allocation, security groups, route tables, and hybrid connectivity back to on-premises environments.

Monitoring & troubleshooting: Implement and maintain network monitoring toolsets; perform deep packet analysis and network tracing using Wireshark and similar tools to diagnose and resolve complex connectivity and performance issues.

Vendor management: Work directly with Cisco and other network equipment vendors on hardware selection, support escalations, lifecycle planning, and licensing.

Automation & optimization: Identify and implement opportunities to automate configuration, monitoring, and management tasks to increase efficiency and reliability.

Project execution: Drive and manage the successful delivery of complex network projects, ensuring milestones are met and issues are resolved promptly.

Stakeholder communication: Develop and deliver clear presentations to leadership and other teams to communicate strategy, status updates, and performance metrics.

Data analysis: Use strong data analysis and Excel skills to understand and reconcile cost, inventory, capacity, trend, risk, and performance metrics.

Collaboration: Work closely with systems, cloud, security, operations, and application teams to integrate best practices across the technology stack.

Documentation & support: Develop and maintain detailed documentation of network designs, configurations, topologies, and processes; provide technical guidance and support to other team members.

Continuous improvement: Research, evaluate, and recommend new technologies, tools, and best practices to advance our network capabilities.

Qualifications:

7-10 years of experience engineering and administering global network environments.
Deep expertise in core networking fundamentals: TCP/IP, subnetting, routing protocols, switching, DNS, DHCP, and QoS.
Strong hands-on experience with VPN and tunneling technologies, including site-to-site VPN design, implementation, and troubleshooting.
Demonstrated experience installing, configuring, and managing enterprise firewalls.
Hands-on experience with network monitoring platforms and packet-level tracing and analysis using tools such as Wireshark.
Experience designing and managing network infrastructure in both on-premises data centers and AWS, including VPCs, VPC peering, CIDR block planning, route tables, and hybrid connectivity.
Demonstrated experience working with Cisco and other network equipment vendors, including hardware deployment, configuration, and support escalation.
Extensive experience working in CLI environments; scripting experience (Python, Bash, PowerShell, Ansible, or similar) is a plus.
Demonstrated ability to drive execution of complex projects with multiple stakeholders.
Excellent data analysis and advanced Excel skills.
Strong written and verbal communication skills. Ability to articulate ideas and thoughts clearly and easily in varied contexts and through multiple mediums.
Strong problem-solving skills and a passion for continuous improvement.
Familiarity with ITIL or other service management frameworks.
Proven experience in directly and indirectly leading engineering teams and projects.
Ability to quickly and independently learn, discover, and understand new technologies, products, software, and deployments.
Bachelor's degree (4-year) required.
Relevant Cisco (CCNP or equivalent) and AWS certifications preferred.

At DXC Technology, we believe strong connections and community are key to our success. Our work model prioritizes in-person collaboration while offering flexibility to support wellbeing, productivity, individual work styles, and life circumstances. We're committed to fostering an inclusive environment where everyone can thrive.
