Unleash your curiosity. Solve what others can't.
At Leidos, we're not just writing code-we're decoding the unknown. Our San Diego research and engineering team tackles some of the most complex challenges in national defense using advanced signal processing, ocean remote sensing, and high-performance computing.
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.
If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.
