Senior Network Engineer

We’re looking for a Senior Network Engineer to join a modern infrastructure and connectivity environment in an enterprise banking setup.

This role is not only about traditional network operations. The main focus is on building, improving, and operating network infrastructure with a strong automation and DevOps mindset. You'll work across data center, on-premises, and edge connectivity, as well as cloud interconnects, firewalls, observability, and infrastructure changes managed through controlled and auditable processes.

The environment is regulated, so reliability, documentation, change management, auditability, and security-by-design are critical. You'll work closely with the Cloud Platform, Security, and Product teams to ensure network services are stable, secure, and ready to support business-critical systems.

Responsibilities

• Design, operate, and improve enterprise network infrastructure across data center, on-premises, and edge connectivity environments
• Work with network automation and Network-as-Code practices using tools such as Terraform, Ansible, or Python

• Support plan/apply separation, policy checks, rollback scenarios, and audit evidence for infrastructure changes
• Work with firewall technologies, including FortiGate and Palo Alto
• Support automated firewall rule lifecycle management, including reviews, attestations, cleanup, and rule optimization
• Work with edge and interconnect networking, including routing to and from cloud environments
• Coordinate with cloud platform teams on connectivity, routing, and integration topics
• Apply security-by-design principles across network architecture and operations
• Contribute to segmentation, Zero Trust, NAC, and perimeter protection initiatives
• Improve network observability and reliability using monitoring, NetFlow, alerting, and incident response practices
• Support incident handling, post-incident reviews, documentation, and continuous improvement
• Work in line with change management, audit, compliance, and operational resilience requirements
• Collaborate closely with Security, Cloud Platform, Infrastructure, and Product teams

Requirements

• 3+ years of experience in enterprise networking, including data center, on-premises, and edge connectivity
• Hands-on experience with Network-as-Code or network automation

• Experience with routing, edge networking, and interconnectivity with cloud environments
• Understanding of security-by-design principles
• Knowledge of segmentation, Zero Trust, NAC, and perimeter protection concepts
• Experience with network observability and reliability practices
• Knowledge of NetFlow, monitoring, alerting, incident response, and post-incident reviews
• Experience working in regulated environments with change management, audit, and compliance requirements
