300 million people need your code to change their lives. 

For thousands of years, blind individuals only had 2 mobility solutions: the guide dog and the white cane. Now, your code can change that. You can contribute to developing Pedestrian Autonomous Driving, applied in the Glasses for the Blind, the most innovative mobility solution that will empower millions to live a better life. 

This is for the crazy ones, the ones that believe their work can change the world.


Some of the fields of interest:

-       Develop software, models, and computer vision flows for environmental understanding 

-       Understand the input from the sensors (mostly vision, but not only), and implement algorithms that deal with noise reduction, fusion of multiple sensors, and decision based on data.        

-       Work with concepts such as real-time semantic segmentation / object-detection, advanced processing techniques on video or 3D point clouds (Feature Tracking, 3D Object Tracking, Visual Odometry, etc.)      

-       Religiously optimize the algorithms to make them as efficient as possible on the target embedded platform. This includes both single threaded and highly parallel (multi-core) algorithms. 


Your Skills

-       First and foremost, curiosity and grit. What you will be doing is on the cutting edge of what is possible and has never been done before.

-       Intersection of ML and Classical Computer Vision, from 1D to 4D.

-       Strong algorithmics skills, with proven experience in complex challenges, Olympiads, or other industry projects.

-       Experience of C++ / Python, Git, developing large projects, etc. 

-       Highly mathematical mind with algorithm optimization knowledge. 

-       Strong documentation skills.

-       Research experience is a plus.  

-       Experience with CUDA, SLAM, 2D/3D Mapping, ROS, is a plus.

-       Graduate of technical universities or equivalent academics.

-       Strong English skills. 


Your life @.lumen


You will be part of the team which changed the world, from Romania. Your work will be pushing limits to improve the lives of millions.

About .lumen


.lumen builds Pedestrian Autonomous Driving, first showcased in the Glasses for the Blind.

There are over 300 million visually impaired individuals worldwide, and while technology advances, the most commonly used solutions for them—guide dogs and white canes—are thousands of years old. At .lumen, we are changing this paradigm.


.lumen is a research startup leveraging the most advanced AI, robotics, and neuroscience technologies to empower the blind. This is no easy task, and we are looking for the best in the world to help us achieve it.


In just four years, .lumen has become one of the most awarded startups globally. From opening Nvidia GTC in front of millions to winning the Red Dot: Luminary award and becoming the first Romanian company to raise over €9 million from the European Innovation Council (EIC), our journey has been remarkable.


Our work is already in the history books, and our story is still being written.
