What Your Day Will Look Like As a Principal Computer Vision / Machine Learning Engineer , you'll play a key role in developing the next generation of computer vision technology within our Innovation Hub. Working at the intersection of computer vision and applied mathematics, you'll transform raw 2D detections from camera systems into accurate 3D positional and trajectory data, ensuring outputs are physically plausible, robust and production-ready. You'll collaborate with software engineers, machine learning specialists and product teams to solve complex technical challenges, helping bring advanced tracking technology into a wider range of sporting environments. Applied Computer Vision Design and develop algorithms that reconstruct accurate 3D positional and trajectory data from 2D detections, applying mathematical and physical modelling of motion, projectiles and object interaction. Computer Vision Systems Design and build computer vision components supporting detection, tracking and calibration workflows across multiple sports. Calibration & Validation Contribute to calibration systems, handling coverage gaps and validating reconstructed trajectories against real-world scenarios. Embedded Deployment Support the optimisation and deployment of algorithms onto embedded NVIDIA Jetson hardware, helping deliver efficient real-time performance on edge devices. Machine Learning Collaboration Work alongside our dedicated Machine Learning discipline, leveraging existing detection models where appropriate while owning the Computer Vision and applied modelling layer built on top of them. Technical Leadership Influence algorithm design, technical architecture and data pipeline decisions within a fast-moving product team while providing technical guidance across complex engineering challenges. Cross-functional Collaboration Partner with data platform, backend and frontend engineers to define data requirements, representative datasets and reliable production outputs. Quality & Reliability Help ensure tracking outputs remain accurate and reliable across challenging real-world environments where conditions can vary significantly. What We Value At Hawk-Eye, we thrive on solving difficult engineering problems through innovation, collaboration and technical excellence. As a Principal Engineer, you'll remain hands-on while influencing the technical direction of our products. You'll work alongside highly skilled engineers across Computer Vision, Machine Learning and Software Engineering to develop innovative solutions that continue to push the boundaries of sports technology. We're looking for someone who enjoys solving complex technical challenges, embraces ambiguity and wants to make a lasting impact through technical leadership and engineering excellence. Skills, Knowledge, and Expertise We're looking for someone with: Extensive commercial experience in Computer Vision with a strong grounding in applied mathematics and physical modelling. Expertise in trajectory estimation, motion reconstruction, projectile physics or similar 2D-to-3D reconstruction problems. Experience designing Computer Vision algorithms for detection, tracking, calibration or reconstruction systems. Experience working with camera-based data sources, tracking pipelines or spatial and temporal datasets. Strong C++ development experience. Python experience for prototyping, experimentation or tooling would be advantageous. Experience deploying or optimising algorithms for embedded or edge GPU hardware, particularly NVIDIA Jetson, is highly desirable. Working knowledge of Machine Learning techniques is beneficial; however, this role is primarily Computer Vision and applied modelling focused rather than Machine Learning research focused. Comfortable working with ambiguity and evolving requirements within a fast-paced, prod
