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
