About the role
Gravis Robotics is a startup that turns heavy construction machines into intelligent and autonomous robots. Our unique combination of learning-based automation and augmented remote control lets one operator safely conduct a fleet of earthmoving machines in a gamified environment. Our team has over a decade of academic experience honing the cutting edge of large-scale robotics, and is rapidly growing to bring that expertise into a trillion dollar industry through active deployments with market leaders.
At Gravis, we engineer solutions at the nexus of hardware and software every day: bringing new perception and control technologies onto powerful, autonomous machines. Our Rooftop Autonomous Control Kit (Rack) combines sensors, compute, communication and networking modules toward a manufacturer-agnostic solution that can be applied to a variety of construction machines regardless of type and age. We are seeking a skilled Global Dynamic Mapping and SLAM Engineer for our perception team: you will help design, develop, test and deploy customized forms of state-of-the-art localization+mapping, state estimation and calibration algorithms—while ensuring production quality implementation and timely execution.
A central focus of the role will be the development of global dynamic mapping systems: building and maintaining consistent, scalable, and semantically meaningful maps of active construction sites as they evolve over time. You will work on methods that fuse lidar, inertial, visual, GPS/GNSS, and fleet-level data to support localization, autonomy, remote operation, site understanding, and long-term map maintenance across multiple machines.
What you will do
Design and deploy large-scale georeferenced mapping systems for autonomous heavy machinery operating in continuously evolving construction environments.
Develop global dynamic mapping pipelines that maintain accurate, up-to-date site representations across evolving terrain, active construction operations, and machine activity.
Define performance metrics, validation methodologies, and benchmarking frameworks for map quality, localization accuracy, robustness, and runtime performance.
Develop scalable multi-sensor fusion and SLAM algorithms that enable robust mapping, localization, state estimation, and calibration in challenging outdoor environments with degraded or intermittent GNSS.
Collaborate closely with multidisciplinary experts to improve the reliability, scalability, and field performance of the overall system.
Ensure production-quality implementation, documentation, and timely execution in a fast-paced, deployment-driven environment
What we are looking for
Master’s or PhD in Computer Science, Robotics, Mechanical Engineering, Electrical Engineering, Geomatics, or a related field.
3+ years of experience developing mapping, SLAM, localization, or state estimation systems for real-world robotic platforms.
Strong understanding of coordinate frames, calibration, sensor synchronization, uncertainty modeling, and real-time robotics systems.
Experience building multi-sensor mapping pipelines using GNSS, LiDAR, cameras, IMUs, and other sensor data.
Strong experience with mapping and SLAM algorithms such as LiDAR-inertial odometry, pose graph optimization, loop closure, scan matching, map alignment, and georeferencing.
Experience writing production-quality C++ and/or Python code in a Linux development environment.
Experience evaluating mapping and localization performance using clear metrics, datasets, field-testing procedures, and benchmarking frameworks.
Additional Beneficial Skills
Experience designing large-scale dynamic mapping systems for unstructured or continuously changing environments.
Experience with global mapping, lifelong mapping, multi-session mapping, semantic mapping, or dynamic scene understanding.
Experience with factor-graph optimization frameworks, mapping backends, geospatial data formats, or large-scale map infrastructure.
Experience deploying perception, mapping, or autonomy systems on real-world robots, construction machines, mining vehicles, agricultural machines, autonomous vehicles, or other heavy equipment.
Ability to reason about system-level tradeoffs between accuracy, robustness, latency, scalability, and maintainability.
Strong communication skills and ability to collaborate across robotics, software, hardware, operations, and product teams.
Ability to prioritize effectively and deliver reliable solutions in a fast-paced, deployment-driven environment.
