Job Purpose

• Operate, and secure mission-critical fab network infrastructure supporting 24x7 semiconductor manufacturing operations

• Ensure ultra-high availability, low latency, and deterministic performance for production systems (MES, Automation, AMHS, Process Control)

• Guarantee network reliability to avoid any production interruption (ITP) and ensure continuous fab operations

Key Responsibilities

Fab Network Support

• Main maintain segmented and highly resilient network architectures (IT / OT segregation, zones, DMZs)

• Support industrial network requirements (low latency, high determinism, redundancy)

• Define standards for factory network topology across production, engineering, and support environments

• Contribute to infrastructure evolution roadmap (digital fab, automation expansion, AI-ready networks)

Operations & 24x7 Availability

• Ensure continuous operation of fab networks (24/7/365) with strict SLA adherence

• Monitor network performance using enterprise tools (e.g., Zabbix, NMS platforms)

• Detect, troubleshoot, and resolve incidents impacting MES, equipment connectivity, AMHS, dispatching systems

• Act as escalation point during incidents impacting production

Incident & Problem Management

• Perform rapid root cause analysis (RCA) for network-related incidents affecting fab operations

• Lead or contribute to ITP avoidance actions and recovery procedures

• Work closely with ProdOps, Automation, MES, and Facilities teams during incident resolution

• Document incidents and drive continuous improvement via 8D / problem management processes

Security & Compliance (Critical in Fab)

• Enforce strict network segmentation between IT and OT environments

• Implement and maintain industrial cybersecurity controls (firewalls, NAC, access control, micro-segmentation)

• Ensure compliance with:

  • Corporate cybersecurity policies
  • TISAX / ISO / SOX / internal audits

• Support vulnerability remediation and security incident handling in production environments

Capacity, Performance & Reliability

• Ensure network capacity supports fab ramp-up, new tool deployment, and automation growth
• Optimize network performance for real-time industrial workloads
• Anticipate bottlenecks and execute capacity planning aligned with fab expansion
• Ensure redundancy (e.g., dual paths, failover mechanisms) to guarantee no single point of failure

Project & Deployment Activities

• Support deployment of new manufacturing tools, MES systems, and automation platforms
• Coordinate network readiness for new production lines, cleanroom expansions, and upgrades
• Collaborate with architects and project managers on infrastructure delivery (design → build → run)
• Participate in factory-wide programs (e.g., EWS, AMHS, digitalization initiatives)

Vendor & Stakeholder Management

• Interface with equipment vendors, automation suppliers, and telecom providers
• Ensure vendor solutions comply with ST network and security standards
• Coordinate with central DTIT teams and local site operations

Documentation & Continuous Improvement

• Maintain accurate network diagrams for fab environments (critical for operations)

• Standardize configurations and operational procedures

• Propose improvements in:

  • Monitoring
  • Automation
  • Resilience

• Contribute to knowledge sharing across sites (Crolles, Agrate, AMK, etc.)

Required Technical Skills

• Strong expertise in:

  • Industrial networking (Layer 2/3, VLANs, QoS, redundancy protocols)
  • Routing protocols (OSPF, BGP)
  • Network security (firewalls, VPNs, segmentation)

• Experience with industrial / OT environments (factory networks, automation systems)

• Knowledge of:

  • MES / Automation / AMHS ecosystem constraints
  • High-availability network design

• Familiarity with monitoring and troubleshooting tools

• Basic understanding of cybersecurity for industrial systems

Soft Skills & Behavior

• Strong sense of ownership and urgency (production-critical environment)

• Ability to operate under high-pressure situations (fab impact)

• Excellent cross-team collaboration (Ops, Automation, MES, Facilities)

• Structured problem-solving and decision-making

• Continuous improvement mindset

Key Performance Indicators (Typical for Fab Role)

• Zero or minimized ITP due to network issues

• High network availability (aligned with fab SLA targets)

• Incident response and resolution time

• Compliance with security and audit requirements

• Successful delivery of network projects supporting fab expansion

Specific Constraints of Fab Environment

• 24/7 on-call or standby support may be required

• Direct impact on production output and revenue

• Need for strict change management and validation procedures

• Operations in a highly regulated and security-sensitive environment
