Position Description

ENSCO, Inc. is seeking an on-site Cyber Intel Analyst / Penetration Tester to support Defensive Cyberspace Operations for Space (DCO-S) capabilities protecting critical U.S. Space Force mission systems.

The Cyber Detection Engineer will evaluate whether cybersecurity sensors, data pipelines, and analytic platforms provide sufficient visibility into adversary activity. The position analyzes endpoint, network, system, and security-event telemetry; maps observable activity to adversary tactics, techniques, and procedures (TTPs); and develops threat-informed products that communicate detection coverage and operational risk.

The successful candidate will collaborate across cybersecurity operations, threat analysis, systems administration, data engineering, and mission-system organizations to translate complex technical findings into actionable guidance.

This position is on-site in Colorado Springs, Colorado.

Responsibilities

• Analyze endpoint, network, system, and security-event telemetry to identify detection opportunities and visibility gaps within DCO-S platforms.
• Map mission-relevant threats, telemetry, and detections to MITRE ATT&CK.
• Develop and maintain ATT&CK Navigator layers, detection-coverage heatmaps, and related threat-informed visualizations.
• Assess adversary TTP coverage and classify techniques as fully covered, partially covered, unobserved, or unassessed.
• Develop, test, document, tune, and automate detection logic, queries, scripts, and repeatable analytical processes.
• Evaluate and validate security data from sensor collection through parsing, normalization, enrichment, ingestion, indexing, storage, search, and visualization.
• Translate findings into operator guidance, including recommended searches, analytical methods, and relevant data sources.
• Support purple-team and threat-emulation activities by determining whether simulated adversary actions produce the expected telemetry and detections.
• Document detection gaps, mission risks, and corrective actions for technical and leadership audiences.
• Collaborate with cyber operators, intelligence analysts, system administrators, network engineers, quality-control personnel, and mission stakeholders to improve detection methodologies and test procedures.
• Travel up to 10% to CONUS and OCONUS locations at the direction of the government customer.

Qualifications Required:

• Bachelor’s degree in cybersecurity, computer science, information technology, engineering, data science, or a related field, plus three or more years of relevant experience. Equivalent education, military training, certifications, and professional experience will be considered.
• Experience in detection engineering, threat hunting, incident response, network defense, security analytics, or SOC operations. Qualifying SOC experience must include functions such as hands-on investigation, SIEM querying, detection tuning, threat hunting, telemetry analysis, or log-source validation.
• Experience applying MITRE ATT&CK to adversary TTPs, telemetry, detection logic, and coverage-gap analysis.
• Experience analyzing endpoint, network, system, or security-event data using SIEM, EDR, network-security-monitoring, or comparable analytics platforms.
• Ability to develop and refine detection logic, queries, scripts, visualizations, and repeatable analytical processes.
• Ability to evaluate whether security data is properly collected, parsed, normalized, enriched, indexed, searchable, and available to cyber operators.
• Strong analytical, problem-solving, organizational, communication, and collaboration skills.
• Ability to document and present complex technical findings to operator, engineering, mission, and leadership audiences.
• Proficiency with Microsoft Word, Excel, and PowerPoint.
• Must meet DoD 8140 qualification requirements for the assigned DCWF work role and proficiency level through an approved certification.
• Active DoD Top Secret security clearance with SCI eligibility and U.S. citizenship required.

Qualifications Desired:

• Experience supporting DoD, USSF, DCO-S, intelligence-community, or other mission-system environments.
• Experience with ATT&CK Navigator, purple-team exercises, adversary emulation, detection-as-code, or Sigma.
• Experience with Bash scripting.
• Current Security+, CySA+, or other certification approved for the assigned DCWF work role and proficiency level.
• Required Certifications: See Required Skills
• U.S. Citizenship Required: Yes
• Security Clearance Required: TS/SCI
• Employment Type: Regular Full-time
• Background Check Type: 7 Year Pre-Employment
• Drug Screen Required: None
• Position Contingent Upon Contract Award: No
