IR Plume Modeling and Simulation Engineer - Qualis Corporation

The SWDC Threat Products and Services organization is responsible for the development and delivery of high fidelity threat data products in support of the Missile Defense Agency’s (MDA’s) ground test event simulations.

The IR Plume Modeling and Simulation Engineer role will help develop, analyze and QC IR plume models, produce IR plume signatures, and be responsible for the verification and validation of signatures.  

This position requires a detail-oriented mid-level engineer responsible for understanding infrared (IR) Plume models, adjusting models to work within the TMC’s generation framework, understanding and verifying results, and providing documentation required for running threat data in Ground Test architectures.  

Essential Functions:

• Understanding of Rocket Exhaust IR plume phenomenology, as well as, modeling and simulation methods and processes.  
• Effectively communicate requirements and processes to fellow engineers, system engineers, software developers.  
• Comfortable working with little or no direct supervision
• Work as an integral member of a geographically dispersed Agile cross functional team.

Requirements

Basic Requirements:

• Level 3: Bachelor’s Degree in a STEM (Science, Technology, Engineering or Mathematics) discipline preferred from an accredited university and 5 years of related experience, or a Master’s degree in a STEM discipline and 3 years experience, or a PhD and 1 year of experience.
• Level 2: Bachelor’s Degree in a STEM (Science, Technology, Engineering or Mathematics) discipline preferred from an accredited university and 2 years of related experience, or a Master’s degree in a STEM discipline and 0 years experience

• Must already possess an active DoD Secret clearance.
• Experience with verification and validation IR plume results
• Ability to collaborate with systems engineers, software engineers, model end users, and MDA ground test stakeholders to ensure product requirements are met.
• Understanding of the flight characteristics, motion, and performance of missile systems.
• Understanding of rocket engines, combustion chemistry, flow field physics, and resulting infrared (IR) signatures.
• Must be self-motivated, able to work in a dynamic team environment.

Preferred Requirements:

• Experience in modeling missile rocket exhaust signature representations.
• Experience running CFD and legacy plume codes (JANNAF SPF, VIPER, CHARM, SOCRATES) or more contemporary codes a plus.
• Experience with MODTRAN a plus.
• Experience developing CFD mesh models from CAD.
• Experience developing chemistry models for rocket exhaust.
• Understanding and experience with High Performance Computing architectures.
• Ability to navigate requirements databases. Strong knowledge of Model Based System Engineering with an understanding of DODAF and SysML.
• Experience in MDA organization with knowledge of OPIR sensor behaviors and models.
• Programming background to include languages such as MATLAB and Python.
• Experience compiling test data and writing reports.
• Experience operating in an Agile SAFe organization.
• Experience with Atlassian tool suite (e.g. Confluence, JIRA, Bitbucket, etc.).
• Strong math, physics, chemistry, or engineering background is preferred.

• Ability to obtain DoD Top Secret Clearance.
