Job Title: Senior Engineer-HPC

Department: Production & Support

Location: Faridabad Position Summary: Accomplished HPC Systems Engineer with 8–10 years of enterprise Linux administration and over 5 years of hands-on experience managing large-scale HPC clusters exceeding 500 cores and multi-petabyte storage environments. Proven expertise in designing, implementing, and optimizing HPC infrastructure, including compute, storage, and high-speed networking, to deliver maximum performance for demanding workloads.

Key Responsibilities: HPC Cluster Management & Optimization - Design, implement, and maintain HPC environments, including compute, storage, and network components.

- Configure and optimize Slurm, PBS Pro, or other workload managers/schedulers for productive job scheduling and resource allocation.
- Implement performance tuning for CPU, GPU, memory, I/O, and network subsystems to meet workload demands.
- Manage HPC filesystem solutions such as Lustre, BeeGFS, or GPFS/Spectrum Scale.

Linux

Administration - Administer enterprise-grade Linux distributions (RHEL, CentOS, Rocky, Ubuntu) in large-scale compute environments.

- Manage kernel upgrades, patching, and security hardening.
- Troubleshoot kernel-level and system-level issues for performance and stability. Automation & Configuration Management - Develop and maintain Ansible playbooks/roles for automated provisioning, configuration, and patching of HPC systems.
- Integrate Ansible with CI/CD pipelines for infrastructure as code (IaC) practices.
- Automate cluster deployment and environment consistency across hundreds of nodes. Monitoring, Troubleshooting & Support - Implement and maintain monitoring tools (e.g., Grafana, Prometheus, Nagios, Ganglia).




- Troubleshoot complex HPC workloads, MPI communication issues, and application performance bottlenecks.
- Provide Tier-3 escalation support for Linux/HPC-related incidents. Collaboration & Documentation - Work closely with research teams, DevOps engineers, and system architects to deliver high-performance solutions.
- Document architecture, SOPs, troubleshooting guides, and performance tuning methodologies.

Requirements Required Skills & Experience - 8–10 years of hands-on Linux system administration experience in production environments.

- 5+ years managing HPC clusters at scale (500+ cores / multiple petabytes of storage).
- Strong Ansible automation skills (complex playbooks, roles, variables, templates).
- Deep understanding of MPI, OpenMP, and GPU/accelerator integration in HPC workloads.
- Proficient with HPC job schedulers (Slurm, PBS Pro, LSF).
- Experience with HPC storage (Lustre, BeeGFS, GPFS).
- Strong knowledge of TCP/IP networking, Infiniband, and RDMA technologies.
- Experience with performance tuning and benchmarking tools (perf, hpc tool kit, Intel VTune, Iperf, fio).
- Scripting proficiency in Bash, Python, or Perl for automation and tooling.

Preferred Qualifications - Experience with containerized HPC (Singularity, Apptainer, or Podman).

- Familiarity with cloud-HPC integration (AWS Parallel Cluster, Azure Cycle Cloud, GCP HPC).
- Knowledge of security compliance standards (CIS benchmarks, STIG).
- Contribution to HPC community tools or open-source projects. Soft Skills - Strong problem-solving and analytical thinking.
- Ability to mentor junior engineers and collaborate across teams.
- Excellent communication skills for technical and non-technical stakeholders.
