Software Engineer

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 a Software Engineer to perform design, development, and hardware/software integration in San Diego, CA for the Advanced Warfare Technology Division.

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.

Join a team of experts in implementing high-performance signal processing on custom system-on-chip (SoC) hardware and building 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, machine learning, RF front end design, and signal processing.
• Designing, implementing, and testing real-time C/C++ software for multi-core embedded systems ranging from bare metal to minimal real-time operating systems, to Linux
• Building software products that utilize third party mathematics and communication libraries
• Implementing low-level drivers for hardware interfaces (e.g. I2C, SPI, UART, PCIe)
• Reading and understanding signal processing algorithms written in MATLAB and implementing and testing the algorithm in optimized C code
• Designing, implementing, and testing software to configure and control RF hardware devices
• Documenting the developed embedded software, demonstration algorithms, and embedded systems
• Clearly communicating technical details of software or demonstration algorithms 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 , 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 Advanced Warfare Technology!

The successful candidate will have the following basic education/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
• Strong understanding of hardware-software interaction and basic computer architecture
• Experience with low-level drivers and hardware interfaces (e.g. I2C, SPI, UART, PCIe)
• Experience using version control (e.g. git, Subversion, etc.) and continuous integration software tools (e.g. Jenkins)
• Ability to debug embedded systems using tools like oscilloscopes and logic analyzers
• 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
• Demonstrated ability to learn new technical skills and concepts
• Understanding of unit test frameworks and test-driven development practices
