​Specialist, IT InfrastructureReq ID: 138375Remote Position: HybridHiring Manager: Paul StannersBand: 08 Region: Asia Country: India State/Province: ChennaiCity: Guindy, ChennaiSummary
We are seeking an experienced, compliance-driven RDL Jump Host Administrator to take ownership of the system administration, security, and access control of our global local jump hosts. Reporting directly to the Lead Network Architect, and working in close alignment with the RDL Network Administrator, you will manage secure access pathways into completely isolated, air-gapped lab networks across multiple HPS Design Centers (including San Jose, Richardson, Thailand, Shanghai, SongShan Lake, Penang, Chennai, and future sites).

The primary objective of this role is to ensure that remote connections terminating from corporate Zscaler ZTNA or customer CyberArk vPAM environments are securely processed, authenticated, and audited.

Crucially, you will implement and maintain the strict compliance frameworks required for Export Controlled VLANs—including interactive terms-of-use banners, mandatory user acceptance gates for shell access, and tamper-proof user-acceptance audit logging.Core Responsibilities
