**Summary:** Meta is building the Metaverse, the "spatial internet" where immersive virtual worlds will coexist with the real world. Spatial AI team under Reality Labs (RL) develops cutting-edge technologies that serve as the foundation of Meta AR/VR products. From tracking & localization to context/semantic understanding, our team takes new technologies from early concept to the product level while prototyping and realizing the new experiences they open up. We are looking for software engineers who are passionate about building tracking & positioning solution for AR/VR devices. In this role, you will be involved in novel technology development using a variety of sensors for inertial and visual motion tracking, spatial mapping & understanding, and sensor fusion for positioning and places identification. You will collaborate with other engineers and researchers in deploying such solutions in RL devices and light-up the next generation experiences such as world-locked rendering, AI powered spatial recommendation, and fitness tracking. **Required Skills:** Software Engineer, Sensor Fusion and Machine Learning Responsibilities: 1. Lead the design and development of advanced tracking and sensor fusion algorithms that leverages visual/IMU inertial tracking with other sensor data (e.g., GPS, WiFi, magnetometer, barometer, etc.) to achieve robust and accurate device position estimation for AR/VR devices in any environments. 2. Follow the state of art tracking & localization technology and define our tech roadmap for adopting these technologies into RL devices. 3. Lead execution and collaboration with multidisciplinary engineering and research teams to drive technologies development from incubation to production. 4. Be a go-to person to escalate the most complex online / production performance issues that require an in depth knowledge. 5. Define projects for other engineers to possibly solve and achieve impact based on your direction. **Minimum Qualifications:** Minimum Qualifications: 6. Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience. 7. Industry experience coding with C++ and Python for design and development of tracking, sensor fusion and machine learning technologies and systems. 8. Experience in designing software systems and machine learning models targeted for edge devices. 9. Demonstrated familiarity with modern machine learning algorithms and experience with modern machine learning frameworks such as PyTorch. **Preferred Qualifications:** Preferred Qualifications: 10. PhD degree in Computer Science, Computer Vision, Machine Learning, Robotics or related technical field. 11. Experience in inertial/visual motion tracking, Kalman filters and state estimation, neural inertial fusion, visual or wireless positioning. 12. Experience mobile optimization, DSP acceleration, Android Open Source Project. 13. Experience in handling sensors such as IMU, magnetometer, WiFi/BLE, Camera and GNSS. 14. Experience with common digital signal processing techniques such as digital filtering, Fourier transform, correlation, and modulation. **Public Compensation:** $85.10/hour to $251,000/year + bonus + equity + benefits **Industry:** Internet **Equal Opportunity:** Meta is proud to be an Equal Employment Opportunity and Affirmative Action employer.
