Senior Computer Vision Engineer (Freelance)

Senior Computer Vision Engineer

Contract: Freelance/Contractor
Pay Rate: 130,000 - 170,000 HUF/day (Hungarian Nationals Only)
Location: Remote

About the Role:
Join Hawk-Eye Innovations (HEI) as a Senior Computer Vision Engineer on a freelance basis. This role focuses on developing real-time skeletal, ball, and game object tracking systems across multiple sports. You’ll work on advanced computer vision pipelines and mathematical models that power our world-leading sports tracking technology.

Your work will contribute directly to live sporting events — solving complex, real-world problems where accuracy and performance truly matter. You’ll collaborate with engineers across teams to build, optimise, and deploy production-grade systems that redefine how sport is seen and experienced.

Core Responsibilities:

• Design and implement computer vision algorithms for real-time tracking across multiple sports.

• Model behaviour from noisy inputs using robust mathematical and statistical methods.

• Develop, test, and optimise C++ code for real-world performance and reliability.

• Prototype and experiment with vision techniques using OpenCV, CUDA, and numerical libraries.

• Build internal tools for visualisation and debugging of vision pipelines.

• Collaborate with cross-functional teams to align on goals, requirements, and delivery.

Technical Skills & Experience:

• Strong background in computer vision fundamentals (e.g. tracking, multi-view geometry).

• Proficiency in C++14 or newer.

• Experience with performance optimisation for CPU and/or GPU.

• Strong mathematical and analytical skills for modelling real-world data.

• Familiarity with OpenCV, Eigen, and other numerical or vision libraries.

• Experience using Git or other version control systems in collaborative environments.

Nice to Have:

• Experience with CUDA or GPU-based computation frameworks.

• Exposure to sensor fusion, Kalman filters, or similar modelling techniques.

• Familiarity with Python for prototyping or experimentation.

• Experience in real-time or embedded systems.

• Interest or experience in sports technology.
