Mission of the Position:
The mission of the Senior Systems Engineer is to design, implement, and safeguard resilient, secure, and compliant infrastructure across a complex portfolio of client environments, ensuring systems are built to withstand operational stress, security threats, and regulatory compliance scrutiny.
Senior Systems Engineers own the technical architecture and long-term stability of client environments including commercial M365, GCCH, on premises infrastructure, as well as virtual on premises networks. They translate business needs and compliance requirements into durable infrastructure designs, make high-impact technical decisions with discipline and foresight, and ensure changes strengthen — not erode — security, reliability, and maintainability. They work in collaboration with the rest of the Infrastructure Team to deliver the technical projects they design.
The Senior Systems Engineer is an active participant in weekly Project Sprint Planning Meetings, as well as Project Debrief Meetings. During New Project Planning Meetings, this Engineer brings forward any and all risks associated with the project, and develops contingency plans for those risks. They carve out time in their schedules to mentor junior technical staff for skill transfer.
Ability to communicate clearly and effectively both verbally and in writing is crucial to ensure clients have a thorough understanding of the solution, changes, and business interruption, and to ensure the team has a thorough understanding of the overarching design as well as how the solution will support client business operations, security, and compliance.
Operating at the intersection of engineering, security, and compliance, Senior Systems Engineers serve as final technical authorities for complex projects and incidents, mentor Service Delivery and Systems Engineers on the Infrastructure Teams and enforce standards that enable CompliancyIT to scale without sacrificing quality, trust, or defensibility.
