This range acknowledges the extensive expertise, leadership capabilities, and significant contributions expected at this level, offering a competitive salary to reflect the value of advanced skills and experience 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.

You will take ownership of our network-policy program — default-deny micro-segmentation across our Kubernetes clusters — and carry the rest of the pillar forward with it: identity-aware service-to-service transport, per-application private access, flow-level visibility, and network configuration managed as reviewed code. This is an engineering role: you will write the policies, the tooling, and the rollout automation yourself, and you will carry changes through other teams' services without breaking delivery.
