Principal Mapping & Localization Engineer

Principal Engineer, Mapping and Localization Location: San Francisco Bay Area, CA (on-site) $200,000 - $260,000 + Equity About the Role FruitionGroup is partnering with an autonomous trucking technology company to find their next Principal Engineer, Mapping and Localization. Our client needs their self-driving vehicle to always know precisely where they sit on the road, down to a few centimeters, by blending data from multiple sensor types - lidar, radar, cameras, inertial sensors, and satellite positioning - together with detailed maps of the road network. The hard part is making that work reliably in places where GPS signal drops out, and on roads that are constantly being re-paved, re-signed, or torn up for construction. You'll shape the architecture, make the build-vs-buy calls, and set the long-term roadmap for localization and mapping, while staying hands-on with the hardest problems in the stack. What You'll Do Set the overall technical direction for how the company approaches localization and mapping, and decide where to build in-house versus adopt existing tools. Architect sensor fusion and odometry solutions suited to real-time operation, drawing on techniques such as factor graphs, Kalman-filter variants, and particle filters. Build out the systems responsible for creating, updating, and serving detailed map data across the fleet. Develop methods for localizing against known reference data and matching what the vehicle sees to features already recorded on the map. Keep maps from going stale by building systems that use data gathered across the fleet to flag real-world changes - new construction, updated signage, and the like. Tune algorithm performance for the compute hardware actually running onboard, weighing trade-offs between speed, memory footprint, and power draw. Give the localization system the ability to recognize and flag when its own confidence is dropping. Help grow more junior engineers through mentorship and hands-on code review. What Our Client Is Looking For Master's or PhD in Robotics, Computer Science, Electrical Engineering, or a closely related technical field. 7+ years in the robotics industry, including at least 4 years specifically building production localization or mapping systems. Deep, expert-level fluency in modern C++ (C++14/17/20), with strong command of memory management in real-time systems. Solid grounding in the math of probabilistic robotics - comfortable with Kalman filtering, nonlinear optimization tools like Ceres, g2o, or GTSAM, and SLAM techniques. Comfortable working with 3D geometry, linear algebra, and coordinate frame transforms such as quaternions and SE(3). Hands-on experience with common robotics libraries such as Eigen, Ceres, PCL, OpenCV, or GTSAM. A plus if you've deployed localization systems on autonomous vehicles or mobile robots, worked with approaches like LOAM, LeGO-LOAM, ORB-SLAM, or VINS, or have experience optimizing for CUDA/GPU or ARM-based embedded platforms.
