Original job description

Description

Are you a software engineer, engine programmer, or low-level C++ engineer who enjoys building core technology for complex real-time software?

Do you enjoy implementing high-performance code, optimizing mathematical models, and turning complex physical problems into reliable, high-fidelity software systems?

Do you want to advance US defense capabilities in Intelligence, Surveillance, Reconnaissance, and Targeting?

If so, we're looking for someone like you to join our team at APL!

We are seeking a Simulation & Physics Software Engineer to help us advance interactive 3D training and high-fidelity, physics-based interactive sensor simulation capabilities. You’ll join a multidisciplinary team moving ambitious ideas from early designs to robust, physics-driven simulation capabilities.

This is an opportunity to apply expertise in software engineering, engine architecture, and computational physics contributing to real-world Intelligence, Surveillance, Reconnaissance, and Targeting (ISRT) missions.

As a Simulation & Physics Software Engineer ...

Your primary responsibility will be to develop, test, and improve real-time software systems that support high-fidelity simulation, interactive 3D visualization, and complex scenario execution.
You will implement and optimize performance-sensitive C++ software involving physics engines, rigid-body dynamics, fluid simulations, runtime architecture, distributed simulation, and real-time mathematical modeling.
You will contribute to the development of models that simulate sensor-environment interactions (e.g., electromagnetic, acoustic, or optical) within a high-performance real-time framework.
You will contribute to the evolution of foundational systems such as state management, physics synchronization, resource loading, serialization, platform abstraction, and simulation execution pipelines.
You will integrate custom physics models, simulation components, rendering systems, data sources, and hardware interfaces into reliable, deterministic interactive capabilities.
You will profile, debug, and optimize complex software systems across CPU, GPU, memory, networking, and real-time frame-budget constraints to ensure physical accuracy is maintained under high performance loads.
You will work collaboratively within a technical team to build software that is performant, maintainable, and mathematically robust.

Qualifications

You meet our minimum qualifications for the job if you...

Have a Bachelor’s degree in computer science, software engineering, physics, mathematics, or a related field.
Have at least three years of relevant software development experience in real-time simulation, engine development, physics-based modeling, graphics, distributed systems, robotics, or related performance-sensitive software.
Have significant experience developing clear and maintainable, high-performance C++ software for real-time, interactive, or simulation-heavy applications.
Have professional experience developing, debugging, and optimizing software within Linux environments.
Have experience working with software architectures for complex technical systems such as physics engines, simulation frameworks, distributed applications, or robotics systems.
Have experience in one or more software areas such as memory management, multithreading, job systems, streaming, serialization, networking, or large-scale C++ architecture.
Are able to obtain an Interim Secret level security clearance by your start date and can ultimately obtain a TS/SCI level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

You'll go above and beyond our minimum requirements if you...

Have a Master’s degree in computer science, software engineering, physics, mathematics, or a related field.
Have experience as an engine programmer, physics programmer, or core technology programmer in a simulation or game industry context.
Have expertise in Python and MATLAB for scripting, data analysis, or mathematical modeling, including experience working with Python and MATLAB bindings to C/C++.
Have experience or a background in signal processing (e.g., digital signal processing, sensor data processing, or waveform analysis).
Have experience with FPGA-based acceleration, RDMA (Remote Direct Memory Access), or high-performance hardware-software integration.
Have experience developing or heavily modifying proprietary physics engines, or working with low-level collision detection, rigid-body dynamics, or particle systems.
Have experience with high-fidelity modeling such as fluid dynamics, multi-body dynamics, aerodynamics, or geospatial/terrain-based simulation.
Have experience with distributed simulation, multiplayer networking, state synchronization, or deterministic simulation environments.
Have experience modernizing, refactoring, or extending large C++ systems while supporting active users, prototypes, or mission operations.
Hold an active Secret, Top Secret, or TS/SCI-level security clearance.
