In the posting’s own words
As a Senior Network Engineer on the Office Technology team, you will own major network services and complex multi-site initiatives from problem definition and design through implementation, migration, and stable operations. You will act as a technical anchor for the team, leading design reviews and difficult troubleshooting, improving standards and automation, and helping other engineers deliver high-quality work.
What it asks for · 9
- A deeply experienced, hands-on network engineer with strong knowledge of TCP/IP, routing, switching, VLANs, wireless, DNS, DHCP , firewalls, and enterprise network security
- Experienced designing and operating resilient network infrastructure across distributed offices or campus environments
- Skilled at diagnosing complex issues using packet captures, logs, flow data, dashboards, and vendor telemetry, and at reasoning from protocols and failure modes
- Comfortable building maintainable automation using scripting, APIs, infrastructure-as-code, version control, testing, and CI/CD practices
- Strong in production engineering practices, including observability, service objectives, capacity planning, change safety, incident response, and post-incident improvement
- Able to take ambiguous problems from problem statement to durable solution, balancing reliability, security, user experience, cost, and delivery speed
- A clear, concise communicator who can lead technical discussions, explain tradeoffs, and build alignment with technical and non-technical partners
- A thoughtful mentor who raises the quality of others’ work without becoming a bottleneck or creating unnecessary process
- Responsible in your use of AI-assisted engineering tools: you protect sensitive data, validate outputs, and know when deterministic automation is the safer choice
Also a plus
- Experience with Datadog or other observability platforms, including network device monitoring, flow analytics, synthetic testing, and service-level reporting
- Experience with Python, Ansible, Terraform, Git-based workflows, or network automation frameworks
- Experience with network access control, RADIUS or 802.1X, segmentation, VPNs, or identity-aware and zero-trust networking
- Experience delivering global office expansions, infrastructure refreshes, or complex migrations in a rapidly scaling organization
What the job covers
- Design resilient, scalable solutions across LAN , Wi-Fi, routing, switching, and office firewalls, with explicit failure domains, capacity assumptions, security controls, and migration paths
- Author RFCs and lead design reviews, clearly documenting goals, constraints, alternatives, decisions, risks, validation, rollout, and rollback
- Build production readiness into network changes through meaningful service objectives, monitoring, alerting, runbooks, capacity planning, failure testing, and operational handoff
- Design reusable automation for provisioning, configuration, policy, compliance, telemetry, and change validation, with appropriate testing, peer review, drift detection, staged rollout, and safe rollback
- Own, alongside other senior engineers and leadership, the health and lifecycle of major network services, using data to improve reliability, coverage, performance, security, supportability, and cost
- Lead difficult incidents and root-cause investigations, communicate clearly during high-impact events, and ensure follow-up work addresses systemic causes
- Evaluate technology and vendor options and make pragmatic recommendations grounded in operability, security, scalability, and business impact
- Partner closely with Security, IT Support, Endpoints, AV , Workplace, Construction, Infrastructure teams, and external vendors on cross-functional initiatives
- Mentor other engineers, delegate effectively, improve team standards and documentation, and raise the quality of design and operational practices
- Participate in operational support, incident response, and planned maintenance activities as appropriate for the team
