Perform special IT projects and system integrations/installations that improve access to information and decrease administrative costs across the organization.
Manage IT staff to achieve business results through communicating job expectations, monitoring, and coaching employees.
Lead by example and stay hands-on in the day-to-day operation.

Administer and scale our government-cloud AI environment (FedRAMP High / GovCloud-hosted models) approved for work involving CUI and ITAR/EAR-controlled technical data, including US-person access controls, logging, and retention.
Enforce the routing rules that keep data in the correct tier: data-marking-driven controls, DLP policies tuned to CUI and export-controlled content, egress monitoring, and clear guardrails at the point of use.
Partner with Security, Export Compliance, and Legal to maintain the acceptable-use policy, model and tool approval process, and audit evidence for AI systems.
Evaluate emerging AI tooling and integrations against our compliance boundary, and give the business a fast, honest answer on what can be adopted, where, and under what conditions.
