The posting

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.

Benefits

  • Salary paid in USD
  • Six-month career advancing opportunities
  • Supportive and friendly work environment
  • Premium medical insurance [employee +family]
  • English language development courses
  • Interest-free loans paid over 2.5 years
  • Technical development courses
  • Employment referral program
  • Premium location in Maadi
  • Social insurance
