Algorithm Software Engineer at Leidos

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. Leidos utilizes its proprietary design methodology for hardware software co-design to manufacture custom SoC and IP for high performance applications.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 parallelized 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 in 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.The successful candidate will be responsible for:Contributing to design and development of advanced systems as a part of multi-disciplinary teams are made up of other software team members and subject matter experts from the areas of systems engineering hardware firmware RF front end design and signal processing.Designing implementing and testing C applications in a real-time environmentUnderstanding and analyzing signal processing algorithms developed in MATLABPorting signal processing algorithms from MATLAB Python or C to C in a multi-core environment on Leidos SoCsOptimizing C code for DSP applications (i.e. leveraging SIMD VLIW or hardware accelerators) and parallel processing to achieve real-time requirementsDeveloping Hardware-in-the-loop (HITL) tests to validate signal processing algorithmsClearly communicating technical details of software to internal and external engineersSupporting system field testing and collection events usually about a week in duration once or twice a yearAt Leidos we value passion for learning. If you believe you have what it takes to succeed in this role and are eager to learn we encourage you to apply. The successful candidate will have the following basic education/experience:Bachelors Degree in Computer Engineering Electrical Engineering or Computer Science4 years of software development experience including strong experience in C/C software development for embedded systemsUnderstanding of linear algebra and probabilityStrong understanding of basic signal processing (e.g. Fourier transforms filtering complex arithmetic)Understanding of hardware-software interaction and basic computer architectureExperience in MATLAB and signal processing algorithmsExperience with build tools such as GCC CMake or MakeExperience using version control (e.g. git Subversion etc.) and continuous integration software tools (e.g. Jenkins)Experience with software testing tools and methodologyExperience in creating and maintaining technical documentation fordeveloped softwareAbility to communicate and share ideas concepts and designs with a team of engineersComfortable working in Linux development environmentsDemonstrated ability and motivation to continually learn new technical skills and conceptsMust have active Secret level security clearance with the ability to obtain a TS/SCI.Bonus education/experience:Masters Degree in Computer Engineering Electrical Engineering Computer Science or equivalentActive security clearance at the Secret level or higherExperience with other programming languages such as MATLAB or equivalent OOP languageExperience with parallel processing (e.g. SIMD VLIW distributed computing)Experience with RF signal processing or related applicationsExperience maintaining tracking and updating ticket/status using Gitlab or similar interfaceAWTLINCIf youre looking for comfort keep scrolling.
