- Investigate & Help diagnose network connectivity issues, performance bottlenecks, and component failures.
- Collaborate with cross-functional teams to support HPC clusters and ensure smooth network operation.
- 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.
- Contribute to the requirements for deployments and guide cross-functional teams during implementation.
- Develop and implement advanced monitoring tools and strategies for network performance.
- Work with senior colleagues to research technologies to improve scalability and security.
- Work with senior colleagues to help optimization initiatives, ensuring maximum efficiency, security, and performance.
- Contribute to new network technologies into existing infrastructure.
- Troubleshoot for complex, high-impact network issues across multiple sites.
- Support with Technical Network incidents, working with other teams to resolve issues quickly.
- Work with your team to support network automation solutions using Ansible, Nornir, and Netmiko.
- Contribute ideas and initiatives to ensure network changes are repeatable, efficient, and error-free.

- Have knowledge of one scripting language (e.g., Python, Bash).
- Analytical and troubleshooting skills.
- Ability to collaborate effectively in team environments.
- Willingness to travel to data centers for deployments and support.
2 years of experience in network engineering, with a focus on high-performance environments is Ideal but not mandatory - Understanding in InfiniBand, RDMA, and advanced network architectures is a Bonus
- Certifications (e.g., CCIE, NVIDIA DPU Certification) is a Bonus
Linux System & Network Security:
- Contribute to network-related Linux administration, ensuring high availability, security, and performance.
- Work with an understanding of security measures, including firewalls, VPNs, and access control policies.
- HPC & InfiniBand understanding:
- Contribute to designing and implementation of HPC network architectures, focusing on InfiniBand configurations for performance-critical environments.
- Work alongside senior colleagues for integration and management of InfiniBand for high-throughput, low-latency computing systems.
- Provide technical input on HPC interconnect issues, optimizing performance across large clusters.
