Job Description:

Help build the intelligence that enables autonomous systems to navigate the world with confidence. In this role, you’ll develop cutting-edge estimation and navigation technology, transforming advanced algorithms into high-performance software that powers resilient autonomy in complex, real-world environments.

 

What you'll do:

  • Research and develop state-of-the-art state estimation and navigation algorithms to enable resilient autonomy in challenging GPS-denied environments.
  • Design and deploy production-grade C++ software for embedded robotic systems operating in dynamic, real-world environments.
  • Build and maintain rigorous unit, integration, and system-level tests to ensure system robustness and safety.
  • Develop and enhance modeling, calibration, and simulation tools for inertial and vision-based navigation systems.
  • Contribute to roadmap planning, feature decomposition, and agile execution alongside a multidisciplinary team of autonomy engineers.
  • Continuously enhance performance analysis, benchmarking, and validation pipelines to drive rapid innovation and improvement.
  • Required qualifications:

    • M.S. in Aerospace Engineering, Electrical Engineering, Robotics, Computer Science, or a related field; minimum 2+ years of related professional work experience if you have an M.S. degree, or 0 years if you are a new Ph.D. graduate.
    • Professional proficiency in modern C++ (C++11 or newer) and strong object-oriented design skills.
    • Hands-on experience deploying low-latency C++ applications to embedded Linux platforms.
    • Professional experience designing and implementing state estimation algorithms (e.g., EKF, UKF, Particle Filters, graph-based optimization).
    • Familiarity with VIO, SLAM, or multi-sensor fusion frameworks (e.g., GTSAM, Ceres, OpenVINS).
    • Strong working knowledge of CI pipelines and automated testing frameworks for C++.
    • Ability to independently deploy high-reliability code suitable for real-world autonomous systems.
    • Familiarity with prototyping in Python or MATLAB is welcome, but this role demands professional C++ production deployment skills. Candidates whose primary experience is in MATLAB or Python are unlikely to find this position a good fit.

    Preferred qualifications:

  • Deep understanding of graph-based optimization for state estimation.
  • Experience developing vision-aided inertial navigation systems (VINS, VIO, Terrain Relative Navigation).
  • Experience with navigation sensor calibration (IMU, GPS, barometers, magnetometers, laser altimeters, cameras).
  • Experience in benchmarking and system validation for real-world navigation performance.
