- Assist with the deployment and configuration of network infrastructures, including large-scale fabric installations from initial setup to operational readiness.
- Maintain and update network documentation and workflows to align with organizational standards.
- Architect, deploy, and optimize advanced network solutions for high-throughput, low-latency environments.
- Lead large-scale deployments and guide cross-functional teams during implementation.
- Develop and implement advanced monitoring tools and strategies for network performance.
- Evaluate and integrate emerging networking technologies to improve scalability and security.
- Mentor junior and intermediate engineers, providing technical leadership.
- Design and implement scalable network architectures with a focus on BGP and OSPF routing protocols.
- Lead network optimization initiatives, ensuring maximum efficiency, security, and performance.
- Oversee the integration of new network technologies into existing infrastructure.
- Lead troubleshooting efforts for complex, high-impact network issues across multiple sites.
- Provide expert guidance on BGP, OSPF, and other advanced routing protocols for large-scale networks.
- Take the lead on critical network incidents, working with other teams to resolve issues quickly.
- Architect and implement advanced network automation solutions using Ansible, Nornir, and Netmiko.
- Develop custom network automation workflows that integrate with other systems in the organization.
- Drive automation initiatives to ensure network changes are repeatable, efficient, and error-free.
Linux System & Network Security:
- Take ownership of network-related Linux administration, ensuring high availability, security, and performance.
- Implement and enforce network security measures, including firewalls, VPNs, and access control policies.
- Mentor junior engineers on best practices for Linux networking and security.
- HPC & InfiniBand Expertise:
- Lead the design and implementation of HPC network architectures, focusing on InfiniBand configurations for performance-critical environments.
- Ensure the integration and management of InfiniBand for high-throughput, low-latency computing systems.
- Provide technical leadership on HPC interconnect issues, optimizing performance across large clusters.
YOUR QUALIFICATIONS:
- Knowledge of InfiniBand configuration and management.
- Familiarity with optical networking hardware and Linux system administration.
- Proficiency in at least one scripting language (e.g., Python, Bash).
- Strong analytical and troubleshooting skills.
- Ability to collaborate effectively in team environments.
- Willingness to travel to data centers for deployments and support.
7+ years of experience in network engineering, with a focus on high-performance environments. - Expertise in InfiniBand, RDMA, and advanced network architectures.
- Advanced certifications (e.g., CCIE, NVIDIA DPU Certification) preferred.
