Develop, improve, and maintain machine learning models that capture demand and supply dynamics in a digital manufacturing marketplace
Build and refine pricing-related models, including cost estimation from CAD geometry, demand forecasting, and partner routing probability models
Apply a range of ML techniques such as tree-based methods, probabilistic models, and deep learning to solve both new and existing challenges
Design, build, and maintain reliable training and inference pipelines on AWS.Run offline experiments, including A/B testing and backtesting, to validate model improvements before deployment
Collaborate closely with ML engineers, data scientists, and domain experts in a cross-functional team.Translate complex marketplace inputs like part geometry, order history, and partner capacity into meaningful features for models
Monitor model performance in production and proactively identify and address drift or degradation
Stay up to date with advancements in machine learning, especially in pricing, marketplace modelling, and manufacturing intelligence
Mentor and support mid-level and junior engineers within the team
What it takes:
Proven experience building and deploying machine learning models in production environments
Strong coding skills in Python (or similar), with experience using ML frameworks such as PyTorch, TensorFlow, or scikit-learn
