Job summary

Leidos LLC is seeking experienced engineers to tackle complex maritime intelligence challenges. You will help characterize undersea threats and support high‑value maritime intelligence products for ONI, guiding decisions from subsystem analysis to integrated combat‑system assessments.

You’ll develop building blocks for system‑of‑systems analysis, translate intelligence into actionable insights, and evaluate vulnerabilities to support countermeasure development and warfighter effectiveness.

Qualifications

• Bachelor’s degree in electrical engineering or a related field; 8+ years of relevant experience or master’s degree and 6+ years of experience.
• Experience in signal processing and/or systems engineering.
• Experience working with SIGINT, OSINT, and other all‑source intelligence.
• Active TS clearance with the ability to obtain SCI.

Responsibilities

• Characterize threat C4ISR architecture from component level upward; assess node hierarchy, timelines, and sensor integration.
• Translate raw intelligence into actionable insights; identify vulnerabilities and inform countermeasure development.
• Evaluate physical and logical network architecture, connectivity, bandwidth, and redundancy.
• Analyze adversary processes from target detection through track reporting and weapon‑launch support.
• Assess how threats coordinate across sensors and platforms; examine cueing protocols and engagement logic.
• Examine track accuracy and latency; evaluate impact of countermeasures on engagement.
• Conduct threat scenarios and assessments to identify system and network vulnerabilities.

Job description

Are you an experienced engineer ready to apply your expertise to some of the nation’s most complex and consequential intelligence challenges? Join Leidos’ Analysis Solutions Business Area, where your work will directly shape maritime threat understanding, strengthen national defense, and influence real-world operational outcomes. In this mission‑driven role, you’ll collaborate with top technical and intelligence professionals, tackle sophisticated multi‑domain systems, and see your contributions impact countermeasure development and Navy decision‑making. If you’re motivated by solving hard problems with strategic importance, this is where your skills can make a lasting difference. Leidos’ Analysis Solutions Business Area is seeking experienced engineers who are eager to contribute to some of the nation’s most important maritime intelligence challenges. In this role, you’ll help characterize undersea naval and multi‑domain threats—from subsystem‑level analysis to integrated combat‑system assessments—and support the creation of high‑value maritime finished intelligence (FINTEL) products for the Office of Naval Intelligence (ONI). Your work will directly advance several mission‑critical objectives:

• Producing objective, tradecraft‑compliant FINTEL (ICD 203)
• Delivering defensible, sourceable intelligence (ICD 206)
• Enabling maximum utility for countermeasure developers
• Helping close the sensor‑to‑shooter loop and strengthen U.S. maritime advantage

What You’ll Do

• C4ISR Architecture Analysis Characterize threat C4ISR architecture from the component level upward. Your assessments will cover node hierarchy, decision timelines, battle‑management logic, sensor integration, data‑fusion requirements, communications/datalink features, and EP integration under jamming or EA conditions. You’ll also generate subsystem‑level engineering building blocks that feed broader system‑of‑systems analysis.
• Sensor‑to‑Vulnerability Integration Translate raw intelligence into operationally actionable insights, closing the loop between sensor performance and architectural vulnerabilities. Your work will highlight decision points, timing constraints, and structural weaknesses that inform EW, EP, and hard‑kill countermeasure development.
• Network Topology & Connectivity Evaluate physical and logical network architecture, connectivity pathways, bandwidth and latency constraints, and redundancy/failover design.
• Full Sensor‑to‑Shooter Characterization Analyze adversary processes from initial target detection through track reporting, fire‑control solution development, weapon‑launch authorization, guidance support, and battle‑damage assessment.
• Cross‑Platform Coordination Assess how threats coordinate across sensors and platforms, including data‑exchange formats, cueing protocols, and cooperative‑engagement logic.
• Targeting Data Quality Examine track accuracy and latency requirements at every handoff point, and evaluate how jamming or countermeasures degrade engagement performance.
• Networked System Vulnerability Research Conduct functional decomposition, develop attack trees, construct threat scenarios, and perform rigorous assessments to identify system and network vulnerabilities.

Required Skills, Education, and Qualifications

• Bachelor’s degree in electrical engineering or a related field, and 8+ years of relevant experience or master’s degree and 6+ years of relevant experience
• Experience in signal processing and/or systems engineering
• Experience working with SIGINT, OSINT, and other all‑source intelligence
• Active TS clearance with the ability to obtain SCI.

Preferred Qualifications

• Graduate degree in Electrical Engineering, Systems Engineering, or a related discipline
• Priority consideration for candidates with an in-scope and active TS/SCI clearance
• Experience with Grapevine
• Experience with Artificial Intelligence

Salary Range for this position is:

$166K to $205K - The final salary offered will be based on experience, education, and clearance.
