Leidos Inc
Description
Today, Advanced Warfare Technology (AWT) is a growing enterprise protecting the warfighter and our national security against ever-adapting threats. Our AWT division currently has an exciting opportunity for an Algorithm Software Engineer to perform design, development, and hardware/software integration in San Diego, CA for the Advanced Warfare Technology Division.
Leidos is a DOD leader in electronic design and chiplet manufacture. Our division primarily focuses on research & development and advanced prototyping, transforming state‑of‑the‑art processing algorithms into real‑time software systems. Projects involve small multi‑disciplinary teams of engineers working together in spiral or agile development environments to meet aggressive customer schedules aimed at near‑term field demonstrations.
In this role, the Algorithm Software Engineer will develop and deploy cutting‑edge signal processing applications to improve the capabilities of the warfighter in modern electronic warfare environments. This role requires understanding signal processing algorithms and deploying them to massively parallel pipelines executed to meet extreme real‑time requirements on Leidos SoCs. The Algorithm Software Engineer is responsible for interfacing with a diverse set of engineers from signal processing, embedded, and RF teams.
Join a team of experts implementing high‑performance signal processing on custom system‑on‑chip (SoC) hardware and building the tools that enable analysis, rapid prototyping, and deployment of cutting‑edge algorithms.
Key Responsibilities
Contribute to design and development of advanced systems as part of multi‑disciplinary teams. These teams comprise software members and subject matter experts from systems engineering, hardware, firmware, RF front‑end design, and signal processing.
Design, implement, and test C applications in a real‑time environment.
Understand and analyze signal processing algorithms developed in MATLAB.
Port signal processing algorithms from MATLAB, Python, or C++ to C in a multi‑core environment on Leidos SoCs.
Optimize C code for DSP applications (e.g., leveraging SIMD, VLIW, or hardware accelerators) and parallel processing to achieve real‑time requirements.
Develop hardware‑in‑the‑loop (HITL) tests to validate signal processing algorithms.
Clearly communicate technical details of software to internal and external engineers.
Support system field testing and collection events, usually about a week in duration once or twice a year.
Required Education and Experience
Bachelor's Degree in Computer Engineering, Electrical Engineering, or Computer Science.
4+ years of software development experience, including strong experience in C/C++ software development for embedded systems.
Understanding of linear algebra and probability.
Strong understanding of basic signal processing (e.g., Fourier transforms, filtering, complex arithmetic).
Understanding of hardware‑software interaction and basic computer architecture.
Experience in MATLAB and signal processing algorithms.
Experience with build tools such as GCC, CMake, or Make.
Experience using version control (e.g., git, Subversion) and continuous integration tools (e.g., Jenkins).
Experience with software testing tools and methodology.
Experience in creating and maintaining technical documentation for developed software.
Ability to communicate and share ideas, concepts, and designs with a team of engineers.
Comfortable working in Linux development environments.
Demonstrated ability and motivation to continually learn new technical skills and concepts.
Must have active Secret level security clearance with the ability to obtain a TS/SCI.
Bonus Education and Experience
Master's Degree in Computer Engineering, Electrical Engineering, Computer Science, or equivalent.
Active security clearance at the Secret level or higher.
Experience with other programming languages such as MATLAB or an equivalent OOP language.
Experience with parallel processing (e.g., SIMD, VLIW, distributed computing).
Experience with RF signal processing or related applications.
Experience maintaining, tracking, and updating tickets/status using GitLab or similar interface.
