A Systems Engineer will collaborate to ensure systems are implemented and maintained in a way that supports regulatory requirements such as CMMC and NIST 800-171. They will participate in meetings, assist with technical guidance, support implementation efforts, support remediation efforts, and contribute to documentation that reflects system states. The role also provides opportunities to learn new technologies, deepen cloud and security expertise, and grow into more senior engineering or technical leadership roles.

• Design, deploy, configure, and maintain secure, reliable systems across client and internal environments, including servers, endpoints, identity platforms, and cloud services.
• Operate and support production systems by troubleshooting and resolving infrastructure, platform, and endpoint issues, collaborating and escalating as necessary to meet service and security expectations.
• Review, validate, and maintain system configurations (e.g., identity and access management, logging and monitoring, encryption, network segmentation, endpoint protection, backup and recovery) to ensure alignment with security, operational, and compliance requirements.
• Implement and maintain system hardening standards, configuration baselines, patching processes, and lifecycle management practices.
• Contribute to the execution and continuous improvement of Platforms Team objectives, including system reliability, scalability, and sustainability.
• Communicate clearly and effectively with technical and non-technical stakeholders via written and verbal channels to explain system behavior, proposed changes, risks, and remediation actions.
• Develop and maintain accurate system documentation, diagrams, runbooks, and standard operating procedures that support operational consistency and audit readiness.
• Support the development and maintenance of internal tooling, templates, and repeatable build processes to improve system consistency, efficiency, and security posture.
