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 moving 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

Stepping across the stack as needed; from low-level optimization in specialized hardware to ML experimentation to data tooling. You also will be taking ownership of problems end-to-end rather than a fixed slice:

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 improvements
Building 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.
