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.
