Our EW 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 Electronic Warfare Division.\nLeidos 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.\nIn 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.\nJoin 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.\nThe successful candidate will be responsible for:\nContributing to design and development of advanced systems as a part of multi-disciplinary teams. These 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.\n\nDesigning, implementing, and testing C applications in a real-time environment\n\nUnderstanding and analyzing signal processing algorithms developed in MATLAB\n\nPorting signal processing algorithms from MATLAB, Python, or C++ to C in a multi-core environment on Leidos SoCs\n\nOptimizing C code for DSP applications (i.e. leveraging SIMD, VLIW, or hardware accelerators) and parallel processing to achieve real-time requirements\n\nDeveloping Hardware-in-the-loop (HITL) tests to validate signal processing algorithms\n\nClearly communicating technical details of software to internal and external engineers\n\nSupporting system field testing and collection events, usually about a week in duration once or twice a year\n\nAt Leidos, we offer competitive benefits http://www.leidos.com/careers/pay-benefits, including 4 or more weeks Paid Time Off, 11 paid Holidays, 401K with a 6% company match and immediate vesting, Flexible Schedules, Discounted Stock Purchase Plans, Technical Upskilling, Education and Training Support, Parental Paid Leave, and much more. Join us and make a difference in Electronic Warfare!\nThe successful candidate will have the following basic education/experience:\nBachelor’s Degree in Computer Engineering, Electrical Engineering, or Computer Science\n\n8+ years of software development experience, including strong experience in C/C++ software development for embedded systems\n\nUnderstanding of linear algebra and probability\n\nStrong understanding of basic signal processing (e.g. Fourier transforms, filtering, complex arithmetic)\n\nUnderstanding of hardware-software interaction and basic computer architecture\n\nExperience in MATLAB and signal processing algorithms\n\nExperience with build tools such as GCC, CMake, or Make\n\nExperience using version control (e.g. git, Subversion, etc.) and continuous integration software tools (e.g. Jenkins)\n\nExperience with software testing tools and methodology\n\nExperience in creating and maintaining technical documentation for developed software\n\nAbility to communicate and share ideas, concepts, and designs with a team of engineers\n\nComfortable working in Linux development environments\n\nDemonstrated ability and motivation to continually learn new technical skills and concepts\n\nMust have active Secret level security clearance with the ability to obtain a TS/SCI.\n\nAt 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.\nBonus education/experience:\nMaster’s Degree in Computer Engineering, Electrical Engineering, Computer Science, or equivalent and 6+ years of experience\n\nActive security clearance at the Secret level or higher\n\nExperience with other programming languages such as MATLAB, or equivalent OOP language\n\nExperience with parallel processing (e.g. SIMD, VLIW, distributed computing)\n\nExperience with RF signal processing or related applications\n\nExperience maintaining, tracking, and updating ticket/status using Gitlab or similar interface\n\nNOTE: for this position the salary range will be $140,000 - $220,000 for qualified candidates with an active clearance and the ability to obtain a TS/SCI clearance. Must be able to work onsite in our San Diego, CA office.\nNKE\nElectronicWarfare\nIf you're looking for comfort, keep scrolling.
