Job Description

We are looking for a Computer Vision Engineer to join our Eye Tracking Team and contribute broadly across the eye tracking stack to deliver algorithms and machine learning models that power gaze-driven features in Varjo mixed reality products. This is a software engineering role with a strong focus on production-grade C++. In a small, fast-moving team you'll wear many “hats” and move fluidly between algorithm development, ML, tooling, data work, and performance optimization as priorities shift. You will develop and optimize C++ algorithm pipelines for accuracy and runtime efficiency, build the systems that measure their performance, and work hands-on with real human-collected eye data to drive improvements. You are an experienced engineer comfortable working in both C++ and Python, with a strong analytical mindset and a genuine interest in applied machine learning.

What You’ll Be Doing

• Developing and improving the ML driven C++ algorithm pipelines behind Varjo's eye tracking, coding in C++ and Python
• Optimizing algorithms and models for accuracy and runtime efficiency on low power resource-constrained hardware
• Building and automating the KPI and testing pipelines that measure eye tracking performance, along with the metrics and visualizations behind them
• Analyzing algorithm and model performance and running data-driven experiments to guide improvementsBuilding and automating the data processing pipelines for the eye data captured in human data-collection studies

Our expectations

• 5+ years of professional software engineering experience with proficiency in C++ for production-grade algorithm code
• Experience working with complex C++ codebases, including debugging, performance optimization, and writing maintainable production software
• Experience optimizing code and models for performance on resource-constrained or embedded hardware
• Strong Python skills for data pipeline and ML work
• Practical experience with computer vision, machine learning, image processing, or sensor fusion
• Experience delivering software within a structured development lifecycle, including work in sprints, continuous integration, quality assurance, and release processes
• Strong data analysis skills: data cleaning, statistical analysis, visualization
• Team player with excellent communication skills in English

A big plus

• Background in any tracking technologies: eye tracking, pose tracking
• Familiarity with camera hardware, optics, and image acquisition

By joining us, you’ll get

• Opportunity to take part in creating the new state-of-the-art in virtual and mixed reality experiences.
• A low-hierarchy culture with minimal bureaucracy and maximum opportunity for you to take charge of your work.
• An international working environment with tons of opportunities to learn and grow with the company.
