Job description

Computer Vision Engineer (Mid-Level)

Contract: Freelance / Contractor
Day Rate: 100,000 – 130,000 HUF/day
Location: Fully Remote (Contract)

Hi, I’m Kieran Smith, Computer Vision Engineering Discipline Lead at Hawk-Eye Innovations. We’re looking for a Mid-Level Computer Vision Engineer to join our Tracking Tooling Squad on a freelance basis.

If you want to contribute to the tools behind some of the most advanced sports tracking systems in the world — and work closely with C++ engineers, analysts, and sports-tech specialists — this could be a great fit.

About the Role

As a Computer Vision Engineer working with the Tracking Tooling Squad, you’ll help develop and maintain tools and applications that support multiple tracking teams across Hawk-Eye.

You’ll work across a wide range of projects — from modernising legacy systems to building new cross‑platform C++ applications and visualisation components that bring tracking data to life.

Your work will be used across multiple sports, including football, tennis, cricket and basketball. You’ll collaborate with a small, experienced team and gain ownership quickly, contributing directly to products that support engineers, analysts and external partners such as the LTA.

This is a delivery‑focused contract where autonomy, clear communication, and strong engineering fundamentals matter.

Key Responsibilities

• Design, develop and maintain tools and applications that support internal tracking teams
• Modernise and improve existing C++ systems
• Develop cross‑platform applications and visualisation components
• Contribute to code reviews, pair programming and agile delivery
• Support debugging, testing and performance improvements across projects
• Take ownership of tasks, show initiative and collaborate with engineers across the Computer Vision discipline
• Work closely with data scientists, developers and external partners on visualisation tooling

Technical Skills & Experience

• Proficiency in modern C++ (ideally C++17 or later)
• Solid understanding of object‑oriented design, multithreading and performance considerations
• Experience with cross‑platform development (Windows, Linux or macOS)
• Familiarity with Git and Visual Studio or similar IDEs
• Ability to work independently in a fast‑paced engineering environment
• Foundational understanding of computer vision concepts and interest in building visualisation tools

Nice to Have

• Experience with Qt for UI development
• Exposure to OpenGL or other rendering/visualisation libraries
• Python for scripting or tooling
• Experience with AWS or cloud services
• Knowledge of databases (SQL or NoSQL)
• Understanding of 3D geometry, rendering or visualisation pipelines
