Join the team as our recent Senior Machine Learning Engineer – India

You will play a key role in advancing Protolabs’ intelligent pricing capabilities by building, maintaining, and improving machine learning models that support real-time quoting for custom-manufactured parts. Working within a complex two-sided marketplace, you will model demand and supply dynamics to improve pricing accuracy and automation, enabling scalable, data-driven decisions even before manufacturing cost inputs are available. You will work closely with engineering, data, product, and domain teams to develop cutting-edge solutions that improve pricing performance and support business growth.

What You'll Do:
Build & Evolve Machine Learning Models

• Develop, improve, and maintain machine learning models that capture demand and supply dynamics within a digital manufacturing marketplace.

• Build and refine pricing-related models supporting intelligent and automated quoting.

• Develop models for cost estimation from CAD geometry, demand forecasting, and partner routing probability.





• Apply a range of machine learning techniques, including tree-based methods, probabilistic models, and deep learning, to solve both recent and existing business challenges.

• Translate complex marketplace inputs such as part geometry, order history, and partner capacity into meaningful model features.

Design & Maintain ML Training and Inference Pipelines

• Design, build, and maintain reliable machine learning training and inference pipelines on AWS.

• Develop scalable workflows for experimentation, model training, validation, and deployment.

• Apply appropriate model versioning and experiment tracking practices.

• Build solutions that support reliable production machine learning systems.

• Contribute to scaling ML infrastructure as model and business requirements evolve.

Validate & Improve Model Performance

• Conduct offline experiments to evaluate and validate model improvements before deployment.
