Job Description
Description Are you a versatile developer who wants to apply modern software practices to solve critical, real-world challenges in strike weapon technology? Are you a software engineer who is naturally curious about how things work and loves collaborating with experts to build the right scientific computing solutions? If so, we're looking for someone like you to join our team at APL. The Strike Guidance, Navigation, Control, And Seekers Group Is Looking For a Simulation Software Engineer To Help Us Architect, Develop, And Modernize Physics-based Simulations Across a Wide-ranging Set Of Programs. Our Group’s Goal Is To Ensure The United States Has a Distinct Technology Advantage In Autonomous Systems By Leading The Next Generation Of Development And Prototyping. We Do This By Providing World Class Design Solutions With a Focus On Guidance, Navigation, and Controls Radio Frequency (RF) and Electro-Optical/Infrared (EO/IR) Sensors Modeling and Simulation (M&S) Hardware/Software Development & Test Multi-Disciplinary Design Optimization We develop and apply simulations to explore these areas across a variety of systems including hypersonic missiles, submarines, cruise missiles, and autonomous flight vehicles. As a member of our team, you will apply advanced programming techniques and design skills to develop sophisticated simulations and algorithms in many or all of these domains. We are committed to developing exceptional talent and fostering a culture of innovation, and as part of our group, you will have a chance to grow your expertise across these technologies. As a Simulation Software Engineer, you will… Develop physics-based models, algorithms, and simulations, applying modern software engineering practices and next-generation technologies to advance our capabilities. Work closely with our cross-disciplinary team of engineers as well as simulation architecture experts across the lab to design innovate solutions to critical challenges. Adapt simulations and algorithms to run on high-performance systems (such as cluster compute environments) or to integrate with test hardware. Qualifications You will meet our minimum qualifications for the job if you… Have a BS in Computer Science, Computer Engineering, Electrical Engineering, Physics, Applied Mathematics, or a related field. Have professional experience developing simulations or other scientific computing applications using C++ or a similar language. Have proficiency with a high-level programming language such as Matlab/Simulink or Python. Have experience developing software both individually and as part of a collaborative team, applying standard software engineering practices such as version control, CI/CD, test development, and containerization. Are passionate about scientific computing and eager to learn domain-specific topics including guidance, navigation, control, and seekers. Are able to obtain an Interim Secret level security clearance by your start date and can ultimately acquire a Top Secret clearance. If selected, you will be subject to a government secret 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 an MS in Computer Science, Computer Engineering, Electrical Engineering, Physics, Applied Mathematics, or a related field. Have at least one year of professional experience developing simulations or other scientific computing applications using object oriented C++. Have experience developing physics-based kinematic simulations (i.e. 6DOF), IR and RF seeker simulations, or simulations involving GNC algorithms. Have experience designing, training, and deploying machine learning solutions to real-world problems, utilizing tools and frameworks such as TensorFlow or PyTorch. Have experience in one or more of the following areas: high performance computing (HPC); Nvidia CUDA or other GPU programming; FPGA programming; highly concurrent systems; signal processing; writing software that interfaces with embedded systems hardware or other hardware-in-the-loop (HIL) simulations. Are skilled developing software in both Linux and Windows environments using CMake and Visual Studio. Currently possess an active Secret security clearance with the ability to obtain a Top Secret clearance. About Us Why Work at APL? The Johns Hopkins University Applied Physics Laboratory (APL) brings world-class expertise to our nation’s most critical defense, security, space and science challenges. While we are dedicated
