A Day in the Life of Industrial sites firewall expert!

Industrial sites firewall expert (senior) plays a critical role in protecting L'Oréal's manufacturing, supply chain, and operational technology (OT) environments. The role ensures robust network segmentation between IT and OT domains, enforces firewall policies aligned with industrial cybersecurity standards (ISA/IEC 62443, NIST), and safeguards production continuity against cyber threats and misconfigurations — while meeting regulatory and audit requirements.

This position follows European business hours: 10:30 AM to 7:30 PM IST, aligned with standard Central European Time working hours. Candidates must be fully comfortable with this permanent schedule.

In this role, You will..

Be responsible for the following: 

Industrial Network Segregation

• Design and implement network segmentation architectures separating IT, OT (Level 0–3), and cloud/SaaS environments across L'Oréal manufacturing plants worldwide.
• Define and enforce industrial DMZ architectures enabling secure data flows (historian replication, SCADA communications, remote access) without direct IT/OT interconnection.
• Lead the identification and remediation of unauthorized cross-zone communications, lateral movement risks, and flat network exposures within industrial environments.

ITSM

• Deliver end-to-end IT/OT service lifecycle management, including incident response, change management, and service requests for firewall and network segregation assets, ensuring SLA compliance.
• Analyze and resolve complex network incidents related to blocked industrial communications, firewall misconfigurations, and OT protocol anomalies, supporting local plant teams and global security operations.
• Participate in identifying new business and regulatory requirements (new plant rollouts, M&A integrations, NIS2 compliance) and propose evolutions to network segmentation models and firewall policy frameworks.

Security Monitoring & Compliance:

• Conduct regular risk assessments, network audits, and penetration test support activities across industrial network segments.
• Generate compliance reports for internal audit, CISO, and external regulatory bodies, demonstrating adherence to ISA/IEC 62443, GDPR, and L'Oréal's internal cybersecurity policies.

Stakeholder Management & Global Service Delivery

• Offshore Delivery: Oversee daily network security operations of run / operations in India, ensuring quality and SLA adherence across all managed plants.
• Plant Engagement: Act as the primary cybersecurity interface for plant IT/OT managers, translating industrial network risks into business impact language for non-technical audiences.

Technical Authority & Operational Excellence

• Multi-Site Security: Oversee firewall policy lifecycle and network segmentation compliance across L'Oréal's global manufacturing and distribution network (on-premise, hybrid, and cloud-connected sites).
• OT/IT Convergence: Lead architectural decisions at the IT/OT boundary, balancing operational continuity requirements with cybersecurity risk reduction objectives.

Support: Manage complex firewall escalations, industrial protocol filtering challenges, and network re-architecture initiatives within plant and corporate environments.

What are we looking for?

Soft Skills

• Strategic Vision: Ability to translate industrial cybersecurity risks into business continuity and compliance implications for senior management.
• Executive Communication: Comfortable presenting complex network security concepts (firewall architectures, OT segmentation) to plant directors, CISO office, and top management.
• Ownership & resilience under pressure: Strong sense of ownership on industrial network security, with the ability to prioritize and make risk based decisions under pressure during production incidents and urgent change windows.
• Multicultural Collaboration: Proven experience working within multicultural, multilingual, and cross-functional teams spanning IT, OT, and manufacturing domains.
• Analytical Mindset: Strong focus on risk-based decision-making, audit readiness, and proactive threat identification in industrial environments.

Technical Skills

For the skills listed below, we distinguish three proficiency levels:

1. Expert level: You can independently design, build and troubleshoot complex solutions in this area. You are the go‑to person for this topic and can guide other developers when needed.
2. Strong experience: You have solid hands‑on experience and can work autonomously on most tasks in this area, occasionally consulting an expert for very advanced cases.
3. Working knowledge / exposure: You understand the main concepts and can contribute with some guidance. You can maintain and adapt existing solutions and are willing to deepen your skills on the job.

• Network Architecture (Strong experience): Proficiency in VLAN design, routing (BGP/OSPF), micro-segmentation, SD-WAN, and Zero Trust Network Access (ZTNA) concepts applied to industrial and corporate environments.
• Mastery of the firewall change management lifecycle (request, design, testing, implementation, post-change validation) and security principles of least-privilege network access and default-deny architectures.
• Strong communication skills, with the ability to simplify network security concepts (segmentation, firewall policies, OT risk) for Manufacturing, Finance, and Internal Audit stakeholders.
• Familiarity with ITSM solutions and IT/OT service lifecycle processes (Build, Run, Roll-out).
