Lead technology specialist

Qualification & Experience:

8+ years of working experience in IT working on Linux environments (RHEL) with development

experience. ● Strong Linux/Red Hat 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, Bee GFS) 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

(Infini Band/Ethernet) with a specific focus on RDMA protocols (Ro CE/i WARP).

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.

Workload & User Enablement

● Data Movement: Orchestrating large-scale data transfers using specialized tools (e.g., XCP,

Aspera, Globus).

● Consulting & Optimization: Advising users on I/O-efficient application development and best

practices for highly scalable workflows.

Candidate Profile (Skills)

● Expertise: Deep knowledge in administering HPC storage stacks and distributed file systems

(POSIX-compliant).

● Network Stack: Expert knowledge of TCP/IP networking, Infini Band fabrics, routing & switching,

and RDMA technologies.

● Automation: Experience in automating provisioning and configuration management (Ansible,

Puppet, Bash/Python).

● Containers & Orchestration: Solid understanding of integrating storage solutions into

containerized environments (Singularity/Apptainer, Kubernetes).

● Good understanding of ITIL processes (Incident, Change, Problem, Service Management);

certification preferred.

● Analytical mindset with strong problem-solving skills, able to diagnose, reproduce, and resolve

complex issues.

● Experience in stakeholder management and user support, with ability to adapt to evolving

business processes.

Good understanding of server architecture and Engineering applications.
