AI Research Engineer, Model Training & Adaptation

Matter Inc • Sunnyvale, CA

12h

About The Position

Our vision is to make manufacturing fully autonomous. Matter is building a fleet of industrial assembly stations driven by close loop neural policies. We train those policies on synthetic data — millions of clips generated in simulation — then co-train on a small number of real demos. We are looking for an exceptional Machine Learning Engineer with a deep focus on modeling to join our fast-paced team. In this role, you will own the end-to-end lifecycle of our core machine learning models for physical AI—from defining the initial data requirements to training, debugging, and deploying them into production.

Requirements

• BS, MS, or PhD in Computer Science, Computer Graphics, Robotics, or a related field (or equivalent experience).
• 5+ years of hands-on industry experience specifically focused on training, debugging, and deploying machine learning models into production systems.
• Deep ML Algorithms Expertise: Strong understanding of modern & foundation ML architectures and model optimization algorithms. Hand on experience in diffusion models, multi-modal architectures. Proven ability to design robust evaluation metrics, A/B tests, and offline/online evaluation frameworks.
• Research Literacy: A strong pulse on the current ML landscape. You read papers regularly and know how to implement and adapt state-of-the-art techniques.
• Reinforcement Learning: Hands-on experience with RL algorithms PPO / SAC / GRPO, reward modeling in a production setting.

Nice To Haves

• Contributions to open-source ML projects or published research in the field.

Responsibilities

• Own the Model Lifecycle: Training, debugging, and deployment of complex machine learning models in a live production environment.
• Algorithmic proficiency: Algorithmic Expertise: Iterate across various neural architectures and post-training techniques to guarantee high model performance, adapting network structures as required.
• Rapid Prototyping & Iteration: Move quickly to test new architectures and techniques. You will build, break, learn, and iterate at a high velocity.
• Define Data & Evaluation Strategy: Establish strict data requirements for your models and design rigorous evaluation strategies to ensure they perform exceptionally well in the real world. Establish strategies to overcome sim2real gaps that can be reused across tasks.
• Bridge Research and Production: Stay up to date with the latest ML publications, open-source models, and industry techniques. Evaluate trade-offs across model families effectively.
• Operate Independently: Drive projects forward with minimal hand-holding. You are comfortable defining your own roadmap and executing against it.
