We’re looking for a Software Engineer / Computer Scientist who thrives on solving hard problems and pushing the boundaries of performance. You’ll join a cross-disciplinary team of scientists and engineers—experts in hydrodynamics, physics, acoustics, and signal processing—to build high-impact software that extracts meaning from massive, complex data sets.

If you’re driven by innovation, energized by collaboration, and ready to see your algorithms power real-world missions—you belong here.

What You’ll Do

• Collaborate with scientists and engineers to design, implement, and optimize advanced algorithms that power next-generation radar, optical, and infrared sensor systems.

• Engineer high-performance backend systems for scientific computing and distributed environments.

• Integrate, refactor, and optimize scientific codebases, ensuring scalability and efficiency.

• Translate and enhance existing code for GPU/CUDA acceleration and parallel/distributed execution.

• Test, document, and evolve complex software in a Linux/Unix environment.

• Work in a collaborative environment that values technical rigor, creativity, and growth.

Required Qualifications

• Bachelor’s degree in Computer Science, Applied Mathematics, Physics, or related field with 6+ years of backend software development experience; or Master’s with 4+ years. Equivalent experience may be considered in lieu of degree.

• U.S. citizenship and ability to obtain a Top Secret clearance (active TS preferred).

• Demonstrated expertise in C/C++ backend software development, including large-scale, performance-critical applications.

• Proven experience with high-performance computing, parallel/distributed processing, and standards such as MPI.

• Hands-on experience with GPU/CUDA programming and optimization.

• Experience with AI/ML and LLM concepts and algorithms

• Strong foundation in advanced mathematics or physics, with the ability to translate theory into functional code.

• Proficiency in Linux/Unix development environments.

• Familiarity with scientific programming, algorithm implementation, and system-level problem-solving.

• Strong understanding of software engineering principles and best practices.

• Excellent written and verbal communication and software documentation skills.

Preferred Qualifications

• Active Top Secret clearance

• Familiarity with Agile development, object-oriented design, and modern software architecture.

• Experience with Git, GitLab, MATLAB, and Fortran.

• Knowledge of multi-threaded or shared-memory applications.

Why Leidos?

You’ll be part of a team that:

• Combines science, technology, and imagination to solve real-world defense challenges.

• Values your curiosity as much as your technical ability.

• Invests in your professional growth through mentorship and hands-on innovation.

At Leidos, your code doesn’t just run—it defends, detects, and delivers.
