## Description

The Security Engineer is responsible for implementing, maintaining, and improving security controls across client environments as well as maintaining internal MSG infrastructure. This role supports incident response, endpoint security, Microsoft 365 security configuration, vulnerability remediation, and compliance execution (ex: NIST / CMMC readiness).

This position requires strong technical ownership, sound judgment, and the ability to operate independently across multiple client environments and MNS internal infrastructure. The Security Engineer is expected to take responsibility for issues through resolution, maintain clear and accurate documentation, communicate effectively with technical and non-technical stakeholders, and consistently apply established security standards and best practices. This role requires the ability to prioritize competing demands, identify and escalate risk appropriately, and contribute to the continued improvement and standardization of MNS security processes, tooling, and client security baselines.

 * Coordinate escalation and communication with internal leadership and clients as needed
 * Participate in post-incident reviews and recommend improvements

Endpoint Security & Hardening

 * Ensure endpoints meet baseline security standards (patching, encryption, AV/EDR coverage, least privilege), both for clients and internal MSG standards
