Bosch Global Software Technologies Private Limited is a 100% owned subsidiary of Robert Bosch GmbH, one of the world's leading global supplier of technology and services, offering end-to-end Engineering, IT and Business Solutions. With over 27,000+ associates, it’s the largest software development center of Bosch, outside Germany, indicating that it is the Technology Powerhouse of Bosch in India with a global footprint and presence in the US, Europe and the Asia Pacific region.

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

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

• 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
