​Leidos’ Defense Systems Electrical Systems department is seeking a talented Embedded Firmware Developer to join our team. The Electrical Systems Department is a design-focused group of engineers specializing in advanced hardware-based products. The individual selected for this position will be an embedded design engineer with varied technical interests and demonstrated engineering and leadership skills. The individual must be a self- starter with experience working with inter-disciplinary teams to solve challenging technical problems. The engineer will lead efforts on and develop architectures for embedded systems integrated into a diverse range of aerospace and military systems including manned/unmanned ground/air vehicles, missiles, defensive radars, and space systems.


​The selected candidate will be a key technical leader in a fast-paced, environment through all phases of the product life cycle from concept development and detailed design through manufacturing, qualification testing, and post-delivery support. The candidate will be responsible for architecting, implementing, and testing embedded firmware and software on a variety of platforms, including FPGAs, microcontrollers, microprocessors, and mixed signal designs. Additional skills such as communications data-link design, digital-signal processing (DSP) design, system design, experience with technical trade studies, and evaluation of technology improvements are a plus.


​With a product focus, the individual is also expected to actively partner with other engineers, project managers, technicians, and the customer to develop solutions that adhere to a diverse set of requirements. This includes architecture decisions from requirements that help inform and drive hardware implementations and working closely with hardware engineers. Additionally, the engineer will support resolution of technical issues that are discovered during the manufacture and test of deliverable products. This will include troubleshooting board-level issues, assessing failures for root cause, and identifying corrective actions. The ideal candidate will thrive in a learning environment that encourages leadership and technical growth.
