About the role

We are seeking a Cyber Network Defense Analyst to join the Compartmented Enterprise Services Office (CESO) effort. The program is establishing a modern secure web service (SWS) operation as part of a highly automated platform supporting a rapidly expanding customer population. The team protects networked systems and services from cyber threats as CESO migrates to a high‑security cloud environment, operating as a 24x7 mission‑critical function providing network defense, monitoring, and incident response.

This is a Contract‑to‑Hire role.

Responsibilities

• Perform computer network incident detection and response activities to detect, correlate, identify, and characterize anomalous activity indicative of threats to the CESO enterprise.
• Monitor security tools and applications for possible malicious activity, investigate associated alerts or indicators, and develop recommendations for a course of action, including mitigation strategies as required.
• Document each event and its associated analysis in a ticketing system with clear, accurate technical writing so it can be reviewed and acted on appropriately.
• Maintain regular face‑to‑face interaction with the customer; handle issues when they are raised by the customer with little or no supervision.
• Positively influence team performance by improving CESO processes and procedures.
• Ensure system checks are performed in a timely manner and that documentation is complete and accurate.
• Assist senior analysts and/or managers with forecasting and modeling current threats.
• Develop a strong rapport with the customer and serve as a trustworthy network defense analyst.
• Collaborate with infrastructure, storage, database, and application teams to align network defense monitoring with CESO's operational requirements as the program transitions to its secure cloud environment.

Requirements

• Bachelor’s degree and 2+ years of related experience; additional
