ML Engineer, II - Learned Behaviors

Meet the Team:
As a Machine Learning Engineer II – Learned Behaviors, you will help develop and deploy behavior models that power decision-making for autonomous trucks. Working closely with teams across perception, prediction, planning, and safety, you will contribute to learned behavior modules that enable safe, efficient, and human-like driving in real-world freight operations.

This role focuses on building, validating, and improving machine learning models and infrastructure that support learned behavior systems within the autonomy stack.

What You’ll Do

• Develop and train machine learning models for learned behavior systems, including approaches such as behavior cloning, imitation learning, and reinforcement learning.

• Implement production-quality ML code to support model training, evaluation, and inference within the autonomy stack.

• Analyze model performance, identify failure modes, and propose improvements to increase robustness and generalization across scenarios.

• Contribute to model training pipelines and data workflows, curating behavior datasets from simulation, fleet logs, and on-vehicle data.

• Collaborate with simulation, validation, and autonomy engineering teams to test and evaluate learned behavior models across diverse driving environments.

• Help integrate learned behavior models into simulation and testing workflows, enabling faster iteration and more comprehensive validation.

• Support the development of tooling and infrastructure that improves experimentation speed, reproducibility, and model iteration.

• Contribute to technical discussions around model architecture and training strategies within the team.

What You’ll Need to Succeed

• Bachelor’s degree in Computer Science, Robotics, Electrical Engineering, Machine Learning, or a related technical field with 4+ years of industry experience, or a Master’s degree with 2+ years of experience.

• Experience applying machine learning techniques such as imitation learning, reinforcement learning, or sequence modeling to robotics, autonomous systems, or complex control environments.

• Strong programming skills in Python and PyTorch, with experience writing production-quality ML code.

• Experience training and evaluating machine learning models using large datasets and scalable compute environments.

• Understanding of ML architectures used in autonomy systems, such as transformers, graph neural networks, or sequence models.

• Experience debugging model behavior, analyzing performance metrics, and iterating on training pipelines.

• Ability to collaborate with cross-functional teams to integrate ML models into larger software systems.

Bonus Points!

• Experience working in autonomous driving, robotics, or simulation-based training environments.

• Experience with reinforcement learning frameworks or distributed training systems (e.g., Ray).

• Experience working with simulation environments or large-scale behavior datasets.

• Familiarity with vehicle dynamics, motion planning, or multi-agent decision-making systems.

• Experience deploying ML models into production or real-world robotics systems.
