Senior Security Engineer, Network & Zero Trust

About the role

We are seeking a hands-on Senior Security Engineer, Network & Zero Trust , to own the network pillar of Sezzle's zero-trust program: every connection explicitly allowed, authenticated by service identity, and attributable after the fact — across our Kubernetes clusters, AWS accounts, and the paths between them.

What you'll do

• Own east-west segmentation across our Kubernetes clusters: design the segmentation model, derive network policies from observed traffic
• Deliver identity-aware transport — design and roll out mutually authenticated, encrypted service-to-service connections (mTLS)
• Keep a live map of the network: VPC peerings, tunnels, cross-account links, and every public entry point — built from cloud APIs and reconciled continuously
• Own segmentation of production and the cardholder-data environment: implement and enforce the CDE and high-trust-tier boundaries
• Partner with IT on private access: evaluate and help deliver per-application access (ZTNA) for engineers and operators reaching production systems

What you need

• 6–11 yrs of experience
• Network security
• SIEM
• Incident response
• Python
• Firewalls
• Kubernetes
• Any graduate

Good to have

• AWS
• Git
• Terraform
• IAM
• LLMs
• Helm

What you get

• ₹4.8 L–₹9 L a month
