Original job description

Qualis LLc is seeking a Modeling & Simulation Systems Engineer II (IR Plume Mod/Sim Systems Engineer) responsible for the development and delivery of high-fidelity threat modeling products in support of the Missile Defense Agency (MDA) and MDA’s Ballistic Missile Defense System (BMDS). Threat Systems Engineering (TSE) is responsible for the development of models and simulations (M&S) used to stimulate element models of MDA’s BMDS, including kinematic missile modeling, IR signature modeling, data production/analysis activities, and maintenance/sustainment activities for the entire TSE software baseline. TSE is a cornerstone element to the Threat and Advanced Simulations Development (TASD) contract. This role requires employees to be onsite daily with no option for remote/hybrid work.

Essential Functions:

Data Engineering and Validation
Handling large-scale, multi-dimensional array datasets
Validating simulated data against measured test or flight data
Analytical Rigor
A natural tendency toward thoroughness and attention to detail
Meticulous verification and validation of large, technical datasets
Troubleshooting and Diagnostics
Systematic Root-Cause Analysis: Ability to logically isolate variables and trace errors to determine if a simulation failure is caused by bad input data, software bugs, or system configuration issues.
Legacy & Custom Code Debugging: Skilled at reading, parsing, and fixing errors in undocumented, in-house tools or legacy scripts (e.g., Python, MATLAB, C++) without relying on external support or documentation.
Log Parsing & Error Identification: Proficient at reading complex log files, console outputs, and stack traces to quickly pinpoint why a simulation run or data conversion tool crashed.
Data Sanity and “Silent Error” Detection: Able to identify and fix “silent failures” – where a tool runs to completion but produces physically or mathematically incorrect data.
Team Collaboration
Excellent verbal and written communication skills.
Ability to prioritize and execute tasks and enjoy working in a collaborative team environment.
Ability to create and work within schedules and timelines

Seeking candidates who find satisfaction in working on challenging and diverse assignments in collaborative settings across all levels.

Required Qualifications:

Bachelor of Science degree in a STEM (Science, Technology, Engineering, or Math) discipline preferred with 2 years of technical experience, or Master’s Degree with 0-2 years’ experience.
Ability and willingness to travel up to 10% of the time to support business needs.
Applicants must have a current active in-scope U.S. Government issued Secret security clearance at the time of application which is required to start.
Proficiency in Python, MATLAB or other scripting languages
Foundational understanding of aerothermodynamics, radiative transfer, fluid dynamics, and molecular spectroscopy
Foundational understanding of data analysis concepts.
Basic conceptual understanding of flight dynamics and aerodynamics

Preferred Qualifications:

Bachelor of Science degree in Aerospace Engineering, Mechanical Engineering, Physics, Optical Sciences, or a related STEM field
Strong math, physics or engineering background
Modeling, Simulation, and automation experience
Experience with atmospheric modeling codes (e.g. MODTRAN)
Experience with JANNAF radiative signature codes
Experience working in Linux based distributed computational environments

Qualis LLC has a comprehensive benefits package based on employment type, location, and applicable agreements that includes:

Health, dental, and vision insurance
401(k) match
Paid time off and Holidays
Educational, professional development and certification reimbursement.
Tax-saving options
Disability and Life Insurance

Qualis LLC is committed to hiring and retaining a diverse and talented workforce who can contribute to the mission and vision of the Company. Our employees are our greatest asset, and we promote a positive work environment, teamwork, professional growth, innovation, community involvement, flexible scheduling and a family-friendly work environment.
