Process Engineer providing engineering support to optimize refinery operations and implement long - term strategies. Involves collaboration with multiple disciplines within the Puget Sound Refinery.
About the role
- Navigation & Sensing Engineer developing advanced positioning and multi-sensor fusion solutions for UAVs at BRINC. Collaborating with cross-functional teams to deliver cutting-edge navigation capabilities.
Responsibilities
- Research, design, and implement state estimation algorithms, including advanced GNSS/INS fusion, and robust filtering approaches.
- Develop high-reliability navigation pipelines integrating GNSS, IMUs/inertial sensors, magnetometers, barometers, LiDAR, Radar, and other sensing modalities.
- Build algorithms and tooling for GNSS integrity monitoring, spoofing/jamming detection, signal quality assessment, and fallback/contingency navigation behaviors.
- Develop calibration, synchronization, and observability pipelines for multi-sensor UAV systems, ensuring consistency and long-term reliability.
- Implement and optimize real-time navigation algorithms on embedded processors, focusing on determinism, computational efficiency, and fault tolerance.
- Validate navigation performance through simulation, log replay, hardware-in-the-loop, and real-world flight testing in a variety of GPS conditions.
- Collaborate with cross-functional teams to ensure seamless integration with autonomy, controls, avionics, mechanical, and firmware systems.
- Contribute to technical strategy, define best practices, and help guide the evolution of the navigation and sensing stack as systems scale and mature.
Requirements
- Bachelor’s, Master’s, or PhD in Computer Science, Robotics, Electrical Engineering, or a related field with a minimum of 3+ years of industry experience. Note - we are considering candidates for mid-career, senior, and principal positions.
- Strong programming skills in C++ and Python, with experience building real-time systems.
- Experience developing navigation or state estimation systems for robotics or UAVs, with a foundation in GNSS, INS, and/or multi-sensor fusion.
- Proficiency with GNSS technologies, including RTK, PPP, differential corrections, and modern signal types (L1/L2/L5, multi-constellation GNSS).
- Familiarity with implementing real-time estimation pipelines on embedded systems or low-latency compute platforms.
- Hands-on experience with UAV or robotics testing, including sensor characterization, data collection, and field validation.
