Network Engineer II

As a Network Engineer II on the Office Technology team, you will implement and support office network solutions across Datadog’s global offices. You will own well-scoped deployment and upgrade work, troubleshoot connectivity issues across LAN, WAN, and Wi-Fi, and partner with senior engineers on larger designs and cross-office initiatives. You will collaborate closely with vendors, Facilities, AV, IT Support, Security, and Infrastructure teams to keep Datadog offices connected, reliable, and observable. This is an IC2 role with a mix of project work and day-to-day operations. You will take ownership of clearly defined areas of the office network stack, execute production changes with care, and grow your ability to design, automate, and improve office network services with support from senior engineers. You will also use AI-assisted tools responsibly to improve troubleshooting, documentation, automation, knowledge discovery, and operational follow-through. At Datadog, we place value in our office culture - the relationships that it builds, the creativity it brings to the table, and the collaboration of being together. We operate as a hybrid workplace to ensure our employees can create a work-life harmony that best fits them. What You’ll Do:  Deploy and configure network solutions for new and existing offices, including switches, wireless access points, routers, and firewalls Own scoped portions of office rollouts and upgrade projects, from planning through execution and validation Partner with ISPs, cabling providers, hardware vendors, and internal teams to turn up new services and resolve issues Troubleshoot LAN, WAN, and Wi-Fi issues using structured debugging methods, packet capture, logs, and performance data Manage routing, VLAN, firewall, and wireless configurations following team standards and change-management processes Contribute to repeatable deployment patterns through templates, documentation, scripting, or infrastructure-as-code Monitor office network health using Datadog dashboards and other tooling, and participate in incident response and post-incident reviews Maintain clear documentation for designs, runbooks, deployment procedures, and operational workflows Collaborate with and provide network guidance to Office Technology Administrators, IT Support, Facilities, AV, Security, and Infrastructure partners Help maintain office network standards, hardware lifecycle plans, and operational consistency across global sites Apply AI-assisted tools thoughtfully to reduce operational toil, improve runbooks, summarize incidents or investigations, and make network operations more repeatable and observable. Who You Are:  Grounded in networking fundamentals, including TCP/IP, routing, switching, VLANs, DHCP/DNS, and wireless concepts Experienced working hands-on with enterprise network equipment such as switches, access points, routers, and firewalls Comfortable executing production changes, validating outcomes, and escalating when risk or ambiguity increases Able to troubleshoot connectivity and performance issues using logs, packet captures, monitoring data, and clear hypotheses Pragmatic, detail-oriented, and interested in improving runbooks, documentation, and operational processes A clear communicator who can work effectively with technical and non-technical partners across offices and time zones Excited to grow your depth in network engineering, observability, automation, and secure office connectivity AI-fluent in your day-to-day work: you use AI-assisted tools to learn, troubleshoot, document, and automate, while validating outputs and protecting sensitive information.   Bonus Points: Experience with Meraki, Aruba, Cisco, Palo Alto, Fortinet, or similar enterprise networking platforms Familiarity with Datadog or other monitoring and observability tools Scripting or automation experience, for example Python, Ansible, Terraform, or vendor APIs Experience supporting multiple office sites, hybrid office environments, office buildouts, or office relocations Familiarity with secure network practices such as segmentation, VPNs, NAC, firewall policy, or zero trust
