We are now offering you an exciting position where you can see into the future and play your part in shaping Varjo’s growth journey. 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.
