Responsibilities

• Design and implement secure cloud infrastructure using Microsoft 365, Azure, and AWS to support defense technology platforms and mission-critical operations
• Partner with the Security Lead on SIEM operations, NIST 800-171 compliance evidence, and security tooling integration — implementing the IT-side controls and log/data pipelines that Security relies on
• Implement and maintain monitoring and alerting solutions to ensure system health, visibility, and rapid response to outages and performance issues
• Manage system patching and updates using endpoint and infrastructure management tools, ensuring systems remain secure and up to date

• Administer and support virtualization platforms (Hyper-V, VMware), including clustering, replication, and high availability configurations
• Plan and execute virtualization migrations and infrastructure upgrades with minimal downtime
• Identify and prioritize automation opportunities based on operational pain points and system inefficiencies
• You should have the following
• Experience at a defense technology startup or fast-paced, high-growth technology company
• Hands-on SIEM implementation or tuning experience (Splunk, Sentinel, etc.) — a strong plus given the partnership model with Security
