CACI is seeking a Senior Attack Surface Testing subject-matter expert to lead assigned continuous-assessment operations for federal cyber assets. This SME designs safe enumeration and validation approaches, directs junior engineers, adjudicates high-risk findings, and ensures rapid reporting and remediation guidance. This position works with the VM-ASE Technical Lead, customer process owners, Cloud/DevOps specialists, and AI-assisted analysis staff to deliver a repeatable, high-confidence assessment service.

This position will provide continuous technical assessment support for full‑time, proactive testing of externally and internally visible federal cyber assets. This expands federal visibility by conducting continual assessments of .gov domains, subdomains, and internet‑facing assets to uncover unknown exposures, validate vulnerabilities, and provide agencies with actionable remediation guidance. This role supports the Continuous Diagnostics and Mitigation (CDM) Program’s mission to safeguard and secure cyberspace in an environment where the threat of cyber-attack is continuously growing and evolving and is responsible for enhancing the security, resilience, and reliability of the Nation’s cyber and communications infrastructure. The CDM Program defends the United States (U.S.) Federal Information Technology (IT) networks from cybersecurity threats by providing continuous monitoring sensors (tools), diagnosis, mitigation tools, and associated services to strengthen the security posture of Government networks.
Responsibilities:

- Lead continuous attack-surface enumeration, vulnerability discovery, controlled validation, change monitoring, triage, reporting, and remediation-support activities.

- Design scan architecture, asset-attribution logic, rate limits, credential and API handling, validation procedures, and deconfliction safeguards for large-scale production assessment.

- Direct and mentor junior engineers; review findings, evidence, false-positive determinations, attack paths, severity, and remediation recommendations.

- Prioritize risk using exposure, exploitability, CISA KEV, EPSS, asset criticality, compensating controls, and mission impact rather than scanner severity alone.

- Lead rapid analysis of newly exposed or high-risk assets and coordinate urgent notifications, customer clarification, and closure validation.

- Define requirements for automation, data normalization, dashboards, AI-assisted triage, and integrations with customer tools and authoritative repositories.

- Produce and technically approve recurring reports, trend analyses, high-risk findings, playbooks, standard operating procedures, and customer briefings.

Qualifications:

Required:

- U.S. citizenship is required.

- The selected candidate must meet eligibility requirements for access to sensitive information and be able to obtain a Public Trust fitness determination (High Risk).

- Ability to work in customer-provided remote environments, use customer-approved tools, and comply with rules of engagement, data-handling requirements, evidence controls, deconfliction procedures, and stop-work criteria.

- Five or more years of attack-surface management, vulnerability assessment, external reconnaissance, penetration testing, or exposure-management experience, including leadership of continuous or large-scale assessment work.

- Deep knowledge of DNS, TLS/PKI, HTTP/S, TCP/IP , routing, service fingerprinting, cloud-hosting patterns, asset attribution, scanner behavior, and manual vulnerability validation.

- Experience designing safe high-volume scanning and enumeration workflows with rate control, scope enforcement, evidence capture, false-positive adjudication, and operation
