Field AI is transforming how robots interact with the real world. We are building risk-aware, reliable, and field-ready AI systems that address the most complex challenges in robotics, unlocking the full potential of embodied intelligence. We go beyond typical data-driven approaches or pure transformer-based architectures, and are charting a new course, with already-globally-deployed solutions delivering real-world results and rapidly improving models through real-field applications.
About the Job
We’re building the estimation and navigation stack that keeps our legged and humanoid robots balanced, aware, and mission-ready—indoors and out, with or without GPS. You’ll design and ship real-time estimators and fusion pipelines that combine IMU and GNSS/GPS/RTK with legged-robot proprioception (joint encoders, torque/force & foot-contact sensors) and exteroception (cameras, LiDAR, radar/UWB). You’ll take algorithms from log-replay to rugged field performance on embedded/Linux targets, partnering closely with controls, perception, and planning.
What You’ll Get To Do
State Estimation for Legged/Humanoid Bases
Design and tune EKF/UKF error-state filters for floating-base pose/velocity, COM, IMU biases, and contact states.
Expose clean interfaces (frames/timestamps/covariances) to whole-body control and footstep planning.
Perception-Aided Localization & Mapping
Stand up VIO/LIO pipelines (stereo/RGB-D + LiDAR) for GPS-denied operation, with map-based relocalization and loop closure.
Add global aids—GNSS/RTK, UWB beacons, prior maps—and blend filtering with factor-graph smoothing when advantageous.
Manage drift/consistency with robust outlier rejection, gating, and integrity monitoring.
Calibration, Timing & Robustness
Own time sync (PTP/Chrony/hardware triggers) and multi-sensor calibration (Allan variance for IMU, camera-IMU/LiDAR-IMU/base extrinsics, encoder offsets).
Build health monitoring, FDIR, and graceful-degradation behaviors for harsh terrain and intermittent sensors.
Establish KPIs (ATE/RTE, NEES/NIS, availability) and automated regression tests.
Tooling, Simulation & Field Operations
Create log-replay pipelines, datasets, and dashboards for rapid iteration and performance tracking.
Validate in sim (Gazebo, Isaac etc) and in the field (stairs, rubble, ramps, slippery floors).
Optimize and deploy on embedded targets (Jetson/x86), profiling latency, memory, and numerical stability.
Hands-on with IMUs (strapdown mechanization, bias/scale, coning/sculling) and GNSS/GPS/RTK (loosely vs tightly coupled INS).
Experience with legged-robot proprioception: joint encoders, foot contact/pressure, torque/force sensors; using kinematic/dynamic constraints in estimators.
Proficiency in modern C++ (14/17/20) on Linux; Python for tooling, analysis, and log processing.
Comfort with SO(3)/SE(3), Lie-group math, and non-linear optimization.
Integration with at least two of: cameras (VIO), LiDAR (LIO/scan-matching), UWB, magnetometer/barometer, radar.
Familiarity with ROS 1/ROS 2, CMake/Bazel, Docker, CI/CD, and reproducible experiments.
Proven track record shipping research-to-production algorithms on real robots with field test cycles.
BS/MS/PhD in Robotics/EE/CS/AE or equivalent practical experience.
The Extras That Set You Apart
Factor-graph SLAM/VIO (GTSAM/iSAM2) and non-linear solvers (Ceres/g2o); hybrid filtering + smoothing in production.
Whole-body/legged tooling, momentum/COM filters, terrain estimation, and contact-rich datasets.
Robustness techniques: adaptive noise models, M-estimators/gating, data association, map-based relocalization.
Experience with GPS-denied navigation at scale (warehouses, construction, urban canyons).
Embedded/GPU acceleration (Nvidia/CUDA) for perception-aided estimation.
Designing calibration & end-of-line test procedures for production.
Compensation and Benefits
Our salary range is generous ($70,000 - $200,000 annual), but we take into consideration an individual's background and experience in determining final salary; base pay offered may vary considerably depending on geographic location, job-related knowledge, skills, and experience. Also, while we enjoy being together on-site, we are open to exploring a hybrid or remote option.
Why Join Field AI?
We are solving one of the world’s most complex challenges: deploying robots in unstructured, previously unknown environments. Our Field Foundational Models™ set a new standard in perception, planning, localization, and manipulation, ensuring our approach is explainable and safe for deployment.
You will have the opportunity to work with a world-class team that thrives on creativity, resilience, and bold thinking. With a decade-long track record of deploying solutions in the field, winning DARPA challenge segments, and bringing expertise from organizations like DeepMind, NASA JPL, Boston Dynamics, NVIDIA, Amazon, Tesla Autopilot, Cruise Self-Driving, Zoox, Toyota Research Institute, and SpaceX, we are set to achieve our ambitious goals.
Be Part of the Next Robotics Revolution
To tackle such ambitious challenges, we need a team as unique as our vision — innovators who go beyond conventional methods and are eager to tackle tough, uncharted questions. We’re seeking individuals who challenge the status quo, dive into uncharted territory, and bring interdisciplinary expertise. Our team requires not only top AI talent but also exceptional software developers, engineers, product designers, field deployment experts, and communicators.
We are headquartered in always-sunny Mission Viejo (Irvine adjacent), Southern California and have US based and global teammates.
Join us, shape the future, and be part of a fun, close-knit team on an exciting journey!
