Senior Navigation and Autonomy Engineer

Senior Navigation and Autonomy Engineer: Rapid Prototyping and Field DemonstrationsThe Contested Autonomy and Navigation Branch at Leidos develops cutting-edge alternative navigation and autonomy technologies for environments where GPS alone cannot be trusted. Based in Huntsville, AL, this role combines algorithm development, simulation, integration, and real-world field testing of autonomous systems for customers including DARPA, NASA, AFRL, ONR, and the U.S. Army. You’ll work on small, fast-moving engineering teams developing and demonstrating advanced capabilities on aircraft, ground vehicles, pedestrians, and maritime platforms. This is a highly hands-on role where you’ll see your work move rapidly from concept to field demonstration and operational deployment. Unlike large production programs, this team focuses on rapid prototyping and transitioning advanced autonomy capabilities from research into operational demonstrations. Engineers on this team are expected to take ownership of technical problems from initial concept through field demonstration and customer evaluation. Engineers regularly participate in field experiments and flight tests, directly supporting customer demonstrations of new autonomy capabilities.Responsibilities:Develop, integrate, and analyze state estimation and multi-sensor fusion algorithms, includingExtended Kalman FiltersUnscented Kalman FiltersParticle FiltersFactor GraphsDevelop, integrate, and analyze computer vision perception and localization techniques includingFeature extraction/matchingOptical flow/visual odometryImage correlationSimultaneous Localization and Mapping (SLAM)Machine learning approaches for all of the aboveDevelopment is performed primarily in MATLAB, Python, C++, ROS, and Linux-based environments.Develop and utilize simulation testbeds to support algorithm testing and assessmentTravel with your team to demo your system to the customer on a variety of platforms, including aircraft, ground vehicles, pedestriansResponsibilities will include the above and also leading teams in the above.Minimum Requirements:Bachelor’s Degree in Computer Engineering, Electrical Engineering, Computer Science, Aerospace Engineering, Mechanical Engineering, or equivalent with 8+ years’ experience or Master’s with 6+ years ‘of experience.Must be a US CitizenMust be eligible to obtain and maintain a U.S. security clearance.Experience with MATLAB, Python, or C++ for algorithm development and analysis. Most early-stage algorithm development and analysis is currently performed in MATLAB.Background in robotics, controls, estimation, or autonomous systemsExperience with either sensor fusion/estimation algorithms (e.g. Kalman Filters, Particle Filters, or Factor Graphs), or with computer vision algorithms (for instance OpenCV). If you have experience with both sensor fusion and computer vision that’s even better!Preferred Skills:Experience working with various sensor types (Inertial Measurement Units, GPS, cameras, LiDAR, etc.)Experience with the Robot Operating System (ROS) and the OpenCV computer vision libraryExperience with interface communication standards / protocols including RS232, RS422, TCP/IP, and UDP to communicate with various sensorsExperience with autonomous system development through robotics competitionsExperience with the Linux operating environmentExperience using version control tools (Git, Subversion, etc).Experience with AI/Machine Learning for computer vision or robotics applicationsExperience leading small engineering teams in a rapid prototyping / R&D environmentNKEIf you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo — because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 — and moving faster than anyone else dares.Original Posting:September 1, 2026For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.Pay Range:Pay Range $107,900.00 - $195,050.00The Leidos pay range for this job level is a general guideline only and not a guarantee of compensation or salary.
