Job description

CIS Secure is seeking a Front-End Software Developer – Modeling & Simulation / HITL to join our team supporting the REACT program at Aberdeen Proving Ground (APG), Maryland.

The Front-End Software Developer will develop modern software interfaces supporting modeling and simulation, hardware-in-the-loop (HITL), and advanced engineering environments for critical national security missions. This role will build intuitive applications that allow engineers and operators to configure systems, visualize complex data, control simulations, and interact with physical and simulated hardware.

ESSENTIAL FUNCTIONS:

• Design and implement user interfaces for engineering, simulation, and test applications.
• Work closely with modeling and simulation engineers, embedded developers, hardware engineers, and systems engineers to translate complex technical workflows into usable software.
• Develop modern front-end applications that integrate with real-time data, simulation environments, and hardware-in-the-loop systems.
• Perform other duties as assigned.

Qualifications

REQUIRED SKILLS:

• Experience developing production-quality front-end applications using modern JavaScript or TypeScript frameworks such as React, Angular, Vue, or similar.
• Strong proficiency with HTML, CSS, JavaScript/TypeScript, and modern web application architecture.

• Experience developing data-intensive interfaces, dashboards, visualization tools, or engineering applications.
• Familiarity with software development practices including Git, automated testing, code review, and CI/CD.
• Ability to work directly with engineers and technical users to translate complex system requirements into effective user interfaces.

DESIRED SKILLS:

• Experience supporting modeling and simulation (M&S) environments.
• Experience developing software for hardware-in-the-loop (HITL) or software-in-the-loop (SITL) systems.
• Experience visualizing or interacting with real-time telemetry, sensor data, system state, or simulation outputs.
• Familiarity with Python, C++, or other languages commonly used in engineering and simulation environments.
• Experience with 2D/3D visualization, geospatial interfaces, plotting, or scientific visualization libraries.
• Familiarity with simulation tools or frameworks such as MATLAB/Simulink, ROS/ROS 2, Unreal Engine, Unity, Gazebo, or similar.
• Experience integrating software with unmanned systems, robotics, embedded systems, test equipment, or physical hardware.
• Experience developing applications for aerospace, defense, autonomy, or other complex engineering environments.

EDUCATION:

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related technical discipline, or equivalent relevant experience.

CLEARANCE:

• Active TS/SCI security clearance required.

OPERATING HOURS AND EXPECTATIONS:

• This position anticipates standard operating hours, with flexibility as required to support program and mission requirements.
