Description Join us in improving and shaping the future of the smart mobility with a group of intelligent, motivated, and dedicated individuals! Leidos operates the Federal Highway Administration’s (FHWA) Saxton Transportation Operations Laboratory (STOL), a US Department of Transportation (USDOT) onsite R&D lab located at the Turner Fairbank Highway Research Center. STOL’s focus is on improving transportation system operations to achieve USDOT’s safety, mobility, sustainability and equity goals. STOL spearheads a variety of exciting R&D projects involving emerging technologies, including but not limited to infrastructure and vehicle connectivity and automation, everything-in-the loop simulation, wireless communication, and experimental data collection and analysis. To promote these efforts, Leidos is looking for a Junior/Mid Simulation Software Engineer – Cooperative Driving Applications (CDA) to join our team! Successful candidates are expected to meet all minimal qualifications and preference is given to candidates with desired qualifications.
