Backend Developer (Python)
at Valerann

Backend Developer (Python), London Based

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 a talented, experienced and hard-working 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.

• At least 3 years experience in developing backend code and data pipelines using Python
• Experience in developing production-ready machine learning code
• Experience with implementing machine vision pipelines or IoT pipelines, for example, streaming, processing data in real-time and in batch, storing data.
• A high level of database proficiency, and experience at working with databases such as PostgreSQL, Athena/Hive and stream engines such as Kafka.
• Experience at developing APIs, for example using Flask or FastAPI.
• Using software development tools such as AWS/Azure, Docker, Terraform, Github, Jira, Airflow, Grafana.

• A person who likes to work in a start-up environment: dealing with uncertainties, working in a small team, and taking initiatives.
• Someone who enjoys engineering complex systems.
• Someone who can identify MVP and develop the right product.
• Someone who is eligible to work in the UK without sponsorship.
