3.23 Robotics State Estimation & Localization Engineer

Field AI
Mission Viejo, CA
Job Description
Field AI is a robotics company focused on building risk-aware and reliable AI systems for embodied intelligence. They are seeking a Field Estimation & Localization Engineer to design and ship real-time estimators and fusion pipelines for legged robots, combining IMU, GNSS/GPS/RTK with proprioception and exteroception. The role involves aligning algorithms from log-replay to field performance and partnering with various stakeholders to improve robot performance and reliability.

Requirements

  • Strong fundamentals in estimation & sensor fusion (EKF/UKF, error-state, observability/consistency, covariance tuning).
  • 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.
  • Proficiency in modern C++ 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.

Benefits

  • Competitive salary
  • Opportunity to work on a challenging project
  • Inclusive work environment
