Job Description

Roles & Responsibilities :

We are seeking a Network Security Architect with a world-class foundation in Core Networking (Layer 2/3) and Secure Site-to-Site Connectivity who would be working on customer products/projects

Key Responsibilities

• Represent OT network architecture with security and compliance, Connectivity architecture design and decision making

• Define reference architectures standards and design frameworks for different OT networks

• Responsible for designing, implementing, and governing secure, resilient, and scalable OT network architectures across industrial/manufacturing environments.

• Develop HLD/LLD, network diagrams, IP addressing schemes, routing and firewall policies, and architecture standards

• Analyze different products from OEMs and make the right decisions that fits with technical and commercial aspects

• Lead Zero Trust adoption for OT environments (ZPA/ZIA, Cisco ZTA)

• Drive architecture for multi-site, multi-region deployments

• Define resiliency, redundancy, and failover strategies

• Lead architecture reviews with Product, Cybersecurity, and Compliance

• Influence vendor selection, technology standards, and long-term roadmaps

• Work with cybersecurity teams on IDS/IPS, network monitoring, NAC, vulnerability management, and secure remote access.

• Coordinate with enterprise IT Network teams for IT/OT convergence and secure remote access.

Qualifications

SKILLS Needed:

First preference: Juniper devices ; Second preference: Cisco devices

• Networking (L2/L3): Switching, STP, VLANs, BGP, OSPF, VRF, routing protocols

• Firewall & Security: Cisco ASA / FTD / FMC, DMZ, Context design, segmentation

• Zero Trust: ZPA / ZIA / Cisco ZTA, MFA, privileged access

• Cloud — AWS (Mandatory): VPC, EC2, Transit Gateway, Direct Connect, virtual firewall

• Enterprise proxy solutions: Hands-on experience with (SOCKS5, Squid, HAProxy, NGINX, Zscaler, Blue Coat, or F5) for secure traffic forwarding and access control

• Standards (Awareness): IEC 62443, NIST CSF, ISO 27001, Purdue Model

• Certifications (Preferred): CCNP / CCIE, AWS Advanced Networking, CISSP

MUST-HAVE REQUIREMENTS

• Layer 2 / Layer 3 Networking — VLANs, STP, BGP, OSPF, VRF — must have designed in real environments, hands-on configuration experience on Cisco devices (Switches/Routers/Firewalls)

• Firewall Architecture — Hands-on Cisco ASA / FTD / FMC, DMZ, Context and segmentation design

• Zero Trust — Replaced VPN with ZTA, experience with Zscaler or Cisco ZTA

• AWS Cloud Networking — VPC, EC2, Transit Gateway, Direct Connect, Security Groups, virtual firewall on EC2 — mandatory, not optional

• Standards Awareness — Knows IEC 62443, NIST CSF, ISO 27001, Purdue Model at a conceptual level — does not need deep implementation experience

CLOUD NETWORKING DETAIL

Candidate must have hands-on AWS experience. Azure or GCP knowledge is a bonus but AWS is required.

• VPC & Subnets — Design public/private subnets, route tables, internet gateway, NAT gateway

• EC2 — Launch and configure instances, assign ENIs, Elastic IPs, IAM roles, Auto Scaling

• Virtual Firewall on EC2 — Deploy Cisco FTDv, Palo Alto VM-Series, or FortiGate as EC2 instances

• Virtual Router on EC2 — Deploy software routers (Cisco CSR 1000V / VyOS), BGP peering in AWS

• Connectivity — Direct Connect, Site-to-Site VPN, Transit Gateway for hybrid and multi-site

• Security — Security Groups, NACLs, AWS Network Firewall, VPC Flow Logs, CloudTrail

STANDARDS — AWARENESS LEVEL IS ENOUGH

Candidate should be able to discuss these standards in an interview — not implement them from scratch.

IEC 62443: Industrial cybersecurity standard — security zones, conduits, and security levels

NIST CSF: Identify, Protect, Detect, Respond, Recover — risk-based security framework

ISO / IEC 27001: Information security management system (ISMS) — how security is governed

Purdue Model: Layered industrial network model — why OT/IT segmentation is designed in levels

NERC CIP: Power grid cybersecurity compliance — awareness is fine for energy sector projects

EXPERIENCE EXPECTATIONS - Mandatory

• Experience — 10 to 12 years in network engineering

• Ownership —

• Architect secure OT/IT integration models aligned to IEC 62443

• Represent OT network architecture in customer, regulator, and executive discussions

• Drive architecture for multi-site, multi-region deployments

Has owned design and implementation decisions — not just followed instructions

• Leadership — Can review team designs, mentor engineers, and drive technical direction along with hands-on demonstration of core skills mentioned above

• Communication — Comfortable speaking to executives, customers, and compliance teams

• Certifications: CCNP

• Certifications (Good-to-have) — CCIE, AWS Certified Advanced Networking, AWS Solutions Architect, CISSP

GOOD TO HAVE — NOT MANDATORY

• Any OT / SCADA exposure — even at project or client level

• Azure or GCP networking — as an addition to AWS

• Infrastructure as Code — Terraform, CloudFormation, or Ansible for network automation
