Support the analytic team lead in the execution of study plans.
Collaborate with military subject matter experts and other stakeholders to characterize architectures and concepts under study in the simulation environment.
Contribute to the development of modeling approaches, experiment designs, and analytic methods.
Instantiate combat system, platform, and behavior models in the simulation environment.
Instantiate kill chains, battle management command and control relationships, and other scenario-specific mission and operational factors in the simulation environment.
Support the development and instantiation of an experiment design in the simulation environment.
Provide technical guidance to less experienced engineers and analysts when required.
Contribute to the creation of quality deliverables and reports and quality control thereof.

Proficiency in C++, Python, or other programming language
Active Top-Secret clearance with Sensitive Compartmented Information (SCI) and Special Access Program (SAP) eligibility

Desired:

Master’s Degree in Computer Science, Operations Research, or other STEM field, with 10 years of relevant experience
6+ years of demonstrated proficiency developing and employing mission-level models within AFSIM or comparable simulation environments
Proficiency in model-based systems engineering tools such as CAMEO
Proficiency in SysML

Scheduled Weekly Hours: 40hrs

Basic Compensation: The offered rate will be based on the selected candidate’s knowledge, skills, abilities and/or experience and in consideration of internal parity.

Compensation range for Virginia is $157,000 to $182,000.

Additional Compensation:

KBR may offer bonuses, commissions, or other forms of compensation to certain job titles or levels, per internal policy or contractual designation. Additional compensation may be in the form of sign on bonus, relocation benefits, short- and long-term incentives, or discretionary payments for exceptional performance.
