This program is establishing a modern secure web service (SWS) operation as part of a state-of-the-art, highly automated platform capable of supporting a rapidly expanding customer population. Our team supports CESO's mission to protect 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 services. We are looking for a self-starter capable of independently performing daily tasks while also working well within a team that requires significant coordination and communication.
Multiple positions are available, including day-shift opportunities in Arlington, VA, and night-shift opportunities in San Antonio, TX. All positions are fully onsite and require an active TS/SCI clearance.
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 potential malicious activity, investigate associated alerts and indicators, and recommend appropriate courses of action, including mitigation strategies as required.
- Document security events and associated analysis in a ticketing system using clear and accurate technical writing to support appropriate review and action.
- Maintain regular face-to-face interaction with the customer and address customer-raised issues with little or no supervision.
- Perform system checks in a timely manner and ensure all associated documentation is complete and accurate.
- Assist senior analysts and/or managers with forecasting and modeling current threats.
- Collaborate with infrastructure, storage, database, and application teams to align network defense monitoring with CESO operational requirements as the program transitions to a secure cloud environment.
QUALIFICATIONS:
- Candidate must currently have a TS/SCI with the ability to obtain and maintain a CI Poly.
- DoDD 8140 compliant certification, at minimum IAT Level II (e.g., Security+ CE), at start.
- Bachelor's degree and 2+ years of related experience; additional experience, education, or training may be considered in lieu of degree.
- Strong knowledge of computing systems, including Windows, Red Hat, and cloud environments (AWS and Azure), with particular expertise in networking, communication protocols, and common security technologies such as IDS/IPS systems and firewalls.
- Experience implementing application and hardware security settings in accordance with vendor and DISA best business practices.
The anticipated salary range for this position is $110,000 - $120,000. This range is a good-faith estimate and not a guarantee of compensation.
