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 nional 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 th extracts meaning from massive, complex da sets. If you're driven by innovion, energized by collaborion, and ready to see your algorithms power real-world missions-you belong here. Wh You'll Do * Collabore with scientists and engineers to design, implement, and optimize advanced algorithms th power next-generion radar, optical, and infrared sensor systems. * Engineer high-performance backend systems for scientific computing and distributed environments. * Integre, refactor, and optimize scientific codebases, ensuring scalability and efficiency. * Transle and enhance existing code for GPU/CUDA accelerion and parallel/distributed execution. * Test, document, and evolve complex software in a Linux/Unix environment. * Work in a collaborive environment th values technical rigor, creivity, and growth., If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the stus 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 step 30 - and moving faster than anyone else dares., Leidos is an industry and technology leader serving government and commercial customers with smarter, more efficient digital and mission innovions. Headquartered in Reston, Virginia, with 47,000 global employees, Leidos reported annual revenues of approximely $16.7 billion for the fiscal year ended January 3, 2025.
