Project

Pricing team

Project Scope
We provide price optimisation solutions in close collaboration with a major UK retailer’s data science team. Together, we build projects to enable quick exploration and productionisation of the ML models and respective optimisation algorithms in a hybrid-cloud environment. The end goal is to provide APIs for the optimiser to solve pricing class problems across multiple business domains.

What you will do
• Implementation of the end-to-end Machine Learning Lifecycle, starting from data preparation over experimentation to continuous monitoring of data and models in production
• PySpark data pipelines to load and transform large amounts of data to produce smaller, significant features used in modelling and analytics.
• Provisioning all cloud resources that support the model development in AzureML with IaC using Terraform.
• The selection of the best architectural patterns to solve business problems.
• Building robust and maintainable code in the cloud and on-prem to bring models fast and reliably to production.
• Establishing a mature DevOps culture and working on solutions that are reusable in multiple business domains.

Tech Stack
Python (pySpark, Airflow, Azure SDK), Spark K8S cluster, Azure ML and IaC with Terraform, CI/CD with GitHub Actions, Docker

Challenges
There are many pricing problems in the global retailer world which share similar structures and constraints. We focus on building robust solutions that are reusable across multiple domains, leveraging a hybrid on-prem and cloud infrastructure, and ensuring top quality while maintaining quick iterations.

Team
The core engineering team consists of 5-6 talented people in Poland. We collaborate closely with the client’s product management and data science team.

What we expect in general:
• 5+ years of hands-on machine learning engineering experience
• Hands-on experience in deploying Python projects.
• Strong experience in writing high-quality Python code.
• Experience with orchestration tools such as Airflow.
• Knowledge of Spark or other distributed data processing tools.
• Experience with Kubernetes ecosystem as a user.
