Job summary

Nscale in Bellevue, WA seeks a Senior Network Engineering Manager to lead a US-based team responsible for design, validation, and operation of high‑performance networks, including Ethernet fabrics, InfiniBand, and DC networking. You will blend hands‑on technical work with team leadership in a follow‑the‑sun setup.

You’ll own delivery, mentor engineers, implement IaC/GitOps, and drive reliability, performance, and change management across regions while coordinating with cross‑functional partners.

Qualifications

• Proven people-management experience building and leading a technically strong network engineering team.
• Strong technical depth in high-performance Ethernet fabrics (BGP, EVPN, VxLAN, IPv6, LACP, QoS).
• Experience operating InfiniBand/RoCE fabrics for accelerated compute and fabric health management.
• Strong network automation experience: Python and Ansible for provisioning, validation, and compliance in multi-vendor environments.
• Familiarity with IaC and orchestration tools (Terraform, Git-based workflows, CI/CD pipelines).
• Experience with large-scale data center network design (Clos/spine-leaf) and multi-site connectivity.
• Comfort leading incident response at senior escalation levels and driving reliability improvements.
• Nice to have: SONiC-based switching and multi-tenant InfiniBand operations.

Responsibilities

• Lead, coach, and grow a team of four network engineers with clear ownership of technical areas.
• Contribute as a senior individual contributor in fabric design, troubleshooting, automation, and design reviews.
• Own delivery of network workstreams for US deployments from design through validation to operations.
• Drive operational excellence and incident reduction with root-cause analysis and runbooks.
• Implement reference architectures for high-performance Ethernet fabrics using IaC and GitOps practices.
• Provide leadership on InfiniBand operations for accelerated compute clusters and fabric health.
• Ensure accurate network inventory and structured change management.
• Coordinate cross-team dependencies and handovers across regions and shifts.
• Provide visibility of team output and escalation metrics to engineering leadership.

Job description

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.

The range below reflects the base salary for the position. Actual compensation may vary based on job‑related factors such as skill set, experience, education, and location. In addition to base salary, this role may be eligible for bonus, equity, and/or commission programs.
