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 innovative 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 new 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.
