Senior Lead Network Engineer
Overview
Integrant is seeking a senior lead network & infrastructure engineer with 14+ years of experience to provide technical leadership in a fast-paced, complex HPC and AI environment. This is a multi-disciplinary senior role: the core is deep network engineering across Ethernet and InfiniBand fabrics, ideally complemented by hands-on experience in high-performance storage and/or Linux systems operations (SysOps). The senior lead owns fabric architecture and performance, acts as the highest technical escalation point, and works across engineering, platform, storage, and client teams. Adaptability, ownership, and clear communication are key to success in an environment where network performance is critical.
Responsibilities
Develop network configurations and architectures
Operate, maintain, and support Ethernet and InfiniBand networks in a high-performance computing (HPC) and AI environment
Perform ongoing maintenance, upgrades, and lifecycle management of network equipment
Monitor network health, performance, and capacity to ensure reliable, low-latency data flow
Respond to and resolve network and server-related incidents in a timely manner
Run hardware diagnostics and coordinate replacement of failing network components
Support and maintain Linux-based HPC and AI platforms across a wide range of technologies
Collaborate with senior network engineers, software teams, and platform teams on network efficiency, reliability, and security
Assist with configuration, deployment, and operational support of InfiniBand and Ethernet fabrics
Develop and maintain operational documentation, including configuration examples, build guides, and best practices
Support on-site staff during hardware updates, card replacements, and infrastructure changes
Stay current with advancements in data center networking, HPC interconnects, and AI infrastructure technologies
Work within the client ticketing / IT service management system (e.g., TopDesk) to manage incidents and service requests to SLA
Build and maintain automation and tooling (scripting, monitoring integrations, infrastructure-as-code) to improve operational efficiency
Collaborate with software, platform, storage, and client teams on efficiency, reliability, and security
Own the quality of operational documentation: configuration examples, build guides, runbooks, and best practices
Lead design reviews and knowledge-sharing
Work Conditions
Participate in a weekly on-call rotation and respond to network and infrastructure issues after hours when required.
Requirements
14+ years of hands-on experience supporting enterprise or data center-scale networks
Experience working in HPC, AI/ML, or performance-sensitive environments
Practical experience administering InfiniBand (Mellanox/NVIDIA) and Ethernet (Cumulus, SONiC) networks
Strong understanding of data center networking concepts, including servers, storage, and high-speed interconnects
Solid knowledge of Layer 2 and Layer 3 networking, including routing and switching fundamentals
Installing, monitoring, and maintaining very large-scale data center networks
Low-latency, high-bandwidth fabric support and performance tuning for distributed compute and GPU workloads
VXLAN/EVPN architectures and routing protocols such as BGP and OSPF
Exposure to communication libraries such as NCCL, UCX, and MPI
Network management and monitoring tools: UFM, OpenSM, NetQ, or similar
Ability to troubleshoot and resolve network issues in complex, distributed environments
Strong documentation and communication skills
Proven ability to work effectively as part of a team and provide operational support
Preferred (Multi-Skill) Qualifications
Storage: Hands-on experience with high-performance / parallel storage environments (e.g., Lustre, GPFS/Spectrum Scale, BeeGFS, Ceph, NVMe-oF), including storage networking and I/O performance troubleshooting
SysOps / Linux systems: Production Linux systems administration at scale — provisioning, configuration management (Ansible/Salt), kernel/network stack tuning, schedulers (Slurm), containerization
