Principal Service Engineer - Security Focused

Full Job Description

Working from industry-standard cybersecurity frameworks, you will lead multi-team programs spanning secure configuration and policy enforcement, identity and privileged access, vulnerability and configuration compliance, threat detection, and automated response. You will extend NDE's security programs into the cloud space using the industry-standard cybersecurity frameworks- governance and secure configuration standards, exposure and vulnerability management, identity and privileged access, configuration compliance, and threat detection and response - defining the controls, adoption plan, and success measures for each. You will lead AI-driven security operations across cloud, network, and infrastructure environments and define security standards for agentic systems that monitor, troubleshoot, configure, and remediate this estate, embedding AI-first security principles into their architecture, engineering, deployment, governance, and incident response, including least-privilege access for agents that operate network and infrastructure. You will respond to incidents and highly complex issues as a senior technical lead in the on-call (DRI) rotation - driving triage, root-cause analysis, containment, and enforcement actions - and then implement the automations and controls that prevent recurrence. You will build coalitions of support across Cloud Network Engineering, security, identity, and application teams to deliver difficult cross-organization projects, resolve team misalignments, and influence security policy, standards, and architectural review.
