Qualification & Experience: 8 years of working experience in IT working on Linux environments (RHEL) with development experience. ● Robust Linux/RedHat system administration skills for Installing, managing Scientific Computing applications and Performance Analysis and debugging real time application execution. Storage Infrastructure & Data Lifecycle Management ● Design & Engineering: Architectural planning, deployment, and administration of parallel file systems (e.g., Lustre, IBM Spectrum Scale, BeeGFS) and scalable object storage solutions. ● Performance Engineering: Continuous monitoring of storage I/O performance; identification and mitigation of I/O bottlenecks to ensure throughput requirements for compute workloads are met. ● Data Lifecycle Strategy: Preparing for the future implementation of tiered storage concepts (HSM/ILM) to enable automated data migration across different performance tiers (hot-to-cold archiving). Network Architecture & Troubleshooting ● Advanced Diagnostics: Analyzing complex interdependencies between storage backends, file systems,



and fabric architectures. ● Protocol Analysis: Utilizing deep packet inspection tools (e.g., tcpdump, Wireshark) and performance profiling suites (e.g., fio, perf, iostat) to isolate packet loss, latency jitter, or metadata lock contention. ● Interconnect Optimization: Performance tuning of low-latency network configurations (InfiniBand/Ethernet) with a specific focus on RDMA protocols (RoCE/iWARP). Access Control, Security & Compliance ● Identity & Access Governance: Managing NFS (v3/v4) and SMB/CIFS exports, taking into account multi-tenant structures and cross-cluster access. ● Hardening & Compliance: Enforcing network-level export policies (CIDR-based) and implementing POSIX-compliant ACLs as well as POSIX group mappings via LDAP/NIS. ● Data Security: Ensuring data-at-rest and data-in-transit encryption in compliance with regulatory standards (GDPR, Export Control) and institutional security policies.
