Cogent Security Senior+ Infrastructure Engineer role at Cogent Security to build secure, reliable, and cost-effective infrastructure for AI cybersecurity products. Focus on optimizing data platforms, enabling on-prem deployments, hardening security systems, and building agent-first infrastructure.

Responsibilities

We're hiring a Senior+ Infrastructure Engineer to help build a secure, reliable, cost-effective, and agent-forward foundation for running Cogent's products and services.
