[Remote] Senior Manager, Network Engineering
Note: The job is a remote job and is open to candidates in USA. Nscale is seeking a Senior Manager for their Network Engineering Team, which is responsible for the design and operation of networking services that support both internal and customer-facing infrastructures. In this role, you will lead a team of network engineers while also contributing as a hands-on engineer, focusing on delivery, operational performance, and technical leadership.
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
- Implement 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
Skills
- 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
- SONiC-based switching experience
- Production multi-tenant InfiniBand operations (SR-IOV, isolation)
- Experience standing up a new regional team or function
Benefits
- Competitive benefits package including medical
- Dental
- Vision
- Flexible paid time off
- Parental leave
- Retirement plan participation
