We are #VLteam – tech enthusiasts constantly striving for growth. The team is our foundation, that’s why we care the most about the friendly atmosphere, a lot of self-development opportunities and good working conditions. Trust and autonomy are two essential qualities that drive our performance. We simply believe in the idea of ​​“measuring outcomes, not hours”. Join us & see for yourself! About the role Join us to drive business innovation with production-grade ML pipelines . Become a key member of our team as you dive into Big Data, utilise Azure for cloud computing, and deploy solutions on edge devices. Collaborate with Data Scientists on impactful AI-powered projects. Our projects are the tip of the iceberg – expect a landscape of more intriguing and diverse challenges ahead. One of the available projects: T-Rex Project Scope In collaboration with a prominent UK-based retailer's data science team, we create solutions for personalisation challenges, such as web-page product recommendations. The main objective is to deliver well-engineered components that enable work on modelling and experimentation in a hybrid-cloud environment. The ultimate goal is to provide an end-to-end experience stretching from pure data, training different models, and creating APIs to deliver self-improving models. We: - Work on components to support Big Data processing on an on-prem Hadoop cluster. - Ensure that high-quality code is delivered. - Choose the best architecture and tools for the business requirement. - Push the data to the cloud and select the best way to store and process it. - Build robust code and architecture to allow easy productisation of data scientists' models with minimal time and effort. - Enhance monitoring capabilities and reliability. Tech Stack Python: (3.7+) with complete typing PySpark: base for our ETL Azure (incl. Azure ML): model training and serving Tensorflow, pandas, scikit-learn, scipy, nltk Jenkins, Azure DevOps, Terraform, Git @ GitHub Project Challenges Personalisation models use tens of terabytes of input data. We leverage the Hadoop on-prem cluster to extract significant business features and transfer them to the cloud. We adopted the hybrid-cloud model to iterate faster on the business use cases given to us by data scientists. Team The team consists of a Technical Lead and 3-4 Engineers in Poland. These people collaborate closely with the client's UK-based Data Science Unit. For more projects, check out our website.
