Are you an FPGA engineer who enjoys solving complex technical challenges and seeing your designs through from architecture to hardware? Leidos' Defense Space Business Area is seeking an FPGA Engineer to join our team in San Diego, CA. In this role, you'll contribute to advanced sensor and space-related technologies supporting critical national defense missions while working alongside a multidisciplinary team of engineers. This is an opportunity to apply your expertise across the complete FPGA development lifecycle from architecture, design, and implementation through timing closure, integration, and hardware testing. We're looking for engineers who thrive in fast-paced R&D environments and have a passion for developing and delivering high-tech solutions. Experience with space-qualified designs for LEO, MEO, and GEO is a plus, and we value and welcome experience working with organizations such as SDA, RCO, or DARPA. What You'll Work On: You'll develop and test sophisticated FPGA designs for Chemical, Biological, Radiation, Nuclear, and Space sensor systems for federal government customers. You'll also collaborate with a multi-disciplined design team to design and integrate DSP applications for modern System on a Chip (SoC) implementations, including technologies such as Xilinx Zynq UltraScale+ and Xilinx RFSoC. Additional responsibilities include: • Develop and execute FPGA test plans, determine root cause of test failures, and iterate with senior staff to determine design changes to improve FPGA performance. • Support electrical engineering activities including FPGA designs and system integration and testing with CAD and lab activities. • Analyze, design, and implement HDL test benches in hardware description languages, HDL (VHDL, Verilog), for code validation and validation against models. • Able to synthesize, place and route, meeting timing requirements from high-speed FPGAs. • Analyze, design, simulate, and implement designs which interface to common signaling standards, typical IP hard macros such as SERDES, PLLS, etc. and/or protocols such PCIe, 10GBE Ethernet, LVDS, etc. • Use judgment to perform technical troubleshooting and diagnosis of failed equipment and support root cause analysis. • Perform data analysis and write technical reports. • Develop and maintain design documents, functional requirements and interface control documents. What You'll Bring: • BS and 5+ years of relevant experience as an electrical engineer or computer engineer in an R&D environment or Masters with 3+ year of relevant experience. • US Citizenship is required and must be able to obtain/maintain a Top Secret security clearance. • Experience or coursework related to testing FPGA or CPLD designs in an electronics lab. • Fluent in Vivado, Modelsim or Riviera. Fluent in testbenches and self-checking verification methods. • Working knowledge of electronics test equipment like function generators, oscilloscopes, logic analyzers, and lab power supplies. • Well-organized, reliable, attention to detail, demonstrated personal initiative. Ability to multi-task and prioritize workload. Good interpersonal skills and ability to coordinate work with others. Good oral and written communication skills. • Experience working with cross-functional R&D development teams. • Motivated self-starter able to work under minimal supervision and an entrepreneurial approach to roles and responsibilities. • Familiarity with GIT, JIRA, Agile, Scrum. Even Better If You Have: • Masters' degree or higher in Electrical/Computer Engineering with emphasis on digital/ASIC/FPGA design is a plus. • Breadth of experience in a complementary discipline ability to develop image processing algorithms in Matlab and implement them in HDL, FPGA design, or embedded software is a plus. • Experience with Microchip Polarfire and Libero tools is a plus. • Experience reviewing and documenting technical data packages for military products. • Demonstrated mid-level lead position in a large FPGA project. • An active security clearance.
