About the Role
The Network Engineering Team is responsible for the design, validation, and ongoing operation of all networking services that underpin both the internal management platform and the customer-facing cloud infrastructure — including high-performance Ethernet fabrics, InfiniBand, WAN connectivity, and DC networking. The team acts as a 3rd/4th line escalation point for the support organisation.
As Senior Network Engineering Manager, you will lead a US-based team of network engineers, anchoring US-hours network engineering capability within our global follow-the-sun operation. This is a player-coach role: you'll spend a meaningful portion of your time as a hands-on senior engineer — designing, automating, researching and troubleshooting alongside your team — while owning its delivery, development, and operational performance.
What You'll be Doing (Responsibilities)
- Lead, coach, and grow a team of four network engineers: setting clear ownership of technical areas, managing performance, unblocking delivery, and raising capability through mentoring and reviews.
- Contribute directly as a senior individual contributor: fabric design, complex troubleshooting, automation development, and design reviews across Ethernet, InfiniBand, and security domains.
- Own delivery of network workstreams for US deployments — scope, timelines, dependencies, and outcomes — from design through validation and into operations.
- Drive operational excellence and incident reduction: lead root-cause analysis for performance and stability issues, act as a senior escalation point during US hours, and reduce reactive load through runbooks, automation, and measurable SLOs.
- IImplement and uphold reference architectures and standards for high-performance Ethernet fabrics (BGP, EVPN, VxLAN, LACP, QoS), delivered consistently through infrastructure-as-code and GitOps practices — version-controlled configuration, peer-reviewed changes, and automated CI/CD pipelines.
- Provide technical leadership on InfiniBand operations for accelerated compute clusters: Subnet Managers, routing, congestion control, QoS, firmware management, and fabric health.
- Ensure the accuracy of source-of-truth network inventory and configuration data, with changes flowing through structured change management.
- Coordinate cross-team dependencies with deployment, DC operations, platform engineering, procurement, and vendors, ensuring clean handovers across regions and shifts.
- Provide clear visibility of team output, operational metrics, and escalations to engineering leadership.
About You
- Proven people-management experience building and leading a technically strong network engineering team through coaching, performance management, and clear ownership of outcomes — while retaining genuine hands-on depth.
- Strong technical depth in high-performance Ethernet fabrics: hands-on production experience with BGP, EVPN, VxLAN overlays, IPv6, LACP, QoS, and troubleshooting at scale (CLI tooling, Wireshark).
- Experience operating InfiniBand and/or RoCE fabrics for accelerated compute (NVIDIA Quantum/Mellanox), including performance tuning and fabric health management.
- Strong network automation experience: Python and Ansible for provisioning, configuration validation, and compliance across multi-vendor environments; comfortable working in a GitOps model with version-controlled network configuration and CI/CD-driven change.
- Familiarity with modern IaC and orchestration tooling (Terraform, Git-based workflows, pipeline tooling such as GitLab CI/GitHub Actions); experience treating the network as code rather than managing devices by hand.
- Depth in large-scale data centre network design (Clos/spine-leaf) and resilient multi-site connectivity.
- Comfortable leading incident response at senior escalation levels and driving measurable improvements in reliability, performance, and change success.
- Nice to have: SONiC-based switching experience; production multi-tenant InfiniBand operations (SR-IOV, isolation); experience standing up a new regional team or function.
