Network Architect / Network Specialist (On‑Prem, Global)

Position Overview Agile Robots SE is seeking a Network Architect / Network Specialist to define and operate our global on‑premise network across multiple geographies and regional offices. You will lead the design and lifecycle of our campus, branch, and data‑center networks—including high‑performance NVIDIA InfiniBand fabrics that power AI/HPC workloads—while ensuring our controls meet TISAX expectations and internal ISMS requirements. Key Responsibilities 1) Global Architecture & Standards (On‑Prem Only) • Design and document end‑to‑end on‑prem architectures (core/distribution/access/WLAN; DC leaf‑spine). • Establish and maintain global standards: IP addressing & IPAM (NetBox), routing policy, QoS, naming, security baselines, and change control (HLD/LLD, MOP/SOP, rollback). • Define network zoning & segmentation (VLAN/VRF; optional EVPN/VXLAN where justified) across Officeand DMZ networks with clear trust boundaries. 2) Routing, Switching, WLAN & Regional Sites • Engineer BGP/OSPF for WAN & DC; deliver redundancy/failover across carriers and sites. • Own Aruba campus/branch switching and WLAN (coverage, capacity planning, RF hygiene, roaming, WPA2/3‑Enterprise). • Plan and execute site builds/moves/expansions (circuits, last‑mile, demarc, handoffs, cutovers) with measurable downtime windows. 3) Security, Remote Access & Identity • Lead FortiGate policy architecture (zones, NAT, segmentation, IDS/IPS) and FortiGate VPN (IPsec/SSL) for site‑to‑site and remote access, including HA and posture checks. • Implement 802.1X NAC (e.g., Aruba ClearPass) with RADIUS/Active Directory integration; enforce device posture and guest segmentation. • Operate DMZ patterns (reverse proxying, jump hosts, constrained admin planes) and align with TISAX/ISMSrequirements. 4) High‑Performance Networking for AI/HPC • Design, deploy, and maintain NVIDIA InfiniBand fabrics (topology, cabling/optics, partitioning), including subnet managers ( UFM/opensm ), congestion control, and path optimization. • Coordinate with compute/storage teams (e.g., DGX/HPC clusters) on throughput, latency, and scale; plan upgrades and fabric expansions. 5) Reliability, Observability & Automation • Deliver high availability (fast convergence, dual‑homing, link aggregation/MLAG/VLT) and tested DR/failover. • Implement proactive monitoring/alerting (e.g., Zabbix), telemetry/SNMP, and capacity trends; maintain RCAs and SLOs. • Centralize logging with rsyslog and FortiAnalyzer; enforce retention and integrity for audits. • Use NetBox, Ansible/Python, and Git‑based workflows for configuration management, drift control, and repeatable changes. 6) Compliance, Risk & Vendor Management (TISAX Focus) • Map network controls to TISAX expectations (ISMS governance, secure remote access, logging, supplier access, data protection). • Partner with ISMS owner/CISO on risk assessments, controls testing , and evidence preparation for audits (policies, diagrams, logs, change records). • Manage carriers and vendors (Fortinet, Aruba, Dell; integrators); lead RFPs, SLAs, and lifecycle planning. • Mentor regional IT; act as L3 escalation for incidents and major changes. Core Technologies @ Agile Robots SE • Security & Remote Access: FortiGate NGFW, FortiGate VPN (IPsec/SSL), FortiManager/FortiAnalyzer. • Campus/Branch & WLAN: Aruba CX/AOS switching, controllers/APs, ClearPass (802.1X), AirWave (on‑prem mgmt). • Data Center & Fabric: Dell PowerSwitch (OS10), VLT/MLAG; NVIDIA InfiniBand (UFM/opensm). • Foundational Services: VLAN/VRF, BGP/OSPF, QoS; DHCP/DNS, Active Directory, RADIUS; NetBox(IPAM/DCIM). • Observability & Automation: Zabbix, rsyslog (retention policy), NetFlow/sFlow; Ansible/Python, Git. Qualifications Required • 7+ years in enterprise on‑prem networking
