Python Developer (Machine Learning)

Python Develop to help Valerann make complex data and machine learning systems streamlined and scalable


Nobody can predict how we will use vehicles in 10 years. Are all vehicles going to be self-driving? Is traffic going to be controlled using a central or distributed system? Are we going to own cars at all? Whatever the future of autonomous vehicles will be, one thing is certain: we will need roads, good, safe and intelligent ones.

If you want to be part of a dynamic and award-winning start-up and help shape the future

of mobility - join Valerann! We are developing a traffic management solution that is based on a unique vehicle-level data fusion. We ingest streams of data in our cloud environment; we run machine learning algorithms to identify various traffic issues and feed them back in real-time to vehicles and traffic control centres. We have made huge progress, but we need your help to move to the next level.

Our London-based team is looking for an experienced python developer. Your primary focus will be developing our backend services: API and data pipelines that ingest streams of data (IoT, social media, camera feed and connected vehicles data), run machine learning algorithms, in real-time and in batch and store the data in various databases.

  • Initial 30 minutes introduction where we will learn more about your professional background and experience. This will also be a good opportunity for you to understand more about the role and our company.
