Senior Analyst - Modeler


The Johns Hopkins University Applied Physics Laboratory (APL), a national leader in scientific research and development, located midway between Baltimore and Washington, D.C. is seeking an experienced analyst to support cyber assessments and develop models and simulations.

Job Summary:

Play a leading role in the assessment of cyber risk, resilience, and key cyber terrain analysis of military tactical systems. Lead the development and expansion of assessment models and simulations to conduct those assessments. Support research and development of new methods and approaches for the assessment of cyber systems used within the military.

Duties (Listed in order of importance with the estimated amount of time spent at each task):

  • Cyber Analysis – Use current models and analytic methods to quantify the risk of cyber attack to military tactical systems, and assess the resilience of those systems while defending themselves. Lead or support studies that assess risk due to cyber attack, assess the effectiveness of cyber defenses and mitigations, analyze the impact of attacks on the overall mission. Lead or support efforts that investigate the system’s key cyber terrain, and work with teams to investigate key areas for new concepts, improved architecture, and potential operational tactics to improve risk and resilience. (75%)
  • Cyber Modeling – Support the development and maintenance of analytic toolsets used to perform quantitative analysis and assessment. Edit current tools, develop new software to enhance or expand analytic capability, develop methods, algorithms, and visualization capabilities to support cyber analysis. (20%)
  • M&S Strategy – Understand the analytic needs of the group and work with the team and leadership to define future modeling and simulation capabilities. Support the definition of needed tools and methods, definition of requirements and plans to develop those capabilities, and support the research and development of those tools. (5%)
