Job description

Today, Electronic Warfare is a growing enterprise - protecting the warfighter and our national security against ever-adapting threats. 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.
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. 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.
  • Designing, implementing, and testing C applications in a real-time environment
  • Understanding and analyzing signal processing algorithms developed in MATLAB
  • Porting signal processing algorithms from MATLAB, Python, or C++ to C in a multi-core environment on Leidos SoCs
  • Optimizing C code for DSP applications (i.e. leveraging SIMD, VLIW, or hardware accelerators) and parallel processing to achieve real-time requirements
  • Developing Hardware-in-the-loop (HITL) tests to validate signal processing algorithms
  • Clearly communicating technical details of software to internal and external engineers
  • Supporting system field testing and collection events, usually about a week in duration once or twice a year

At 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!
The successful candidate will have the following basic education/experience:
  • Bachelor's Degree in Computer Engineering, Electrical Engineering, or Computer Science
  • 8+ 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, etc.) and continuous integration software 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.

At 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.
Bonus education/experience:
  • Master's Degree in Computer Engineering, Electrical Engineering, Computer Science, or equivalent and 6+ years of experience
  • Active security clearance at the Secret level or higher
  • Experience with other programming languages such as MATLAB, or 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 ticket/status using Gitlab or similar interface

NOTE: 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.
