Job description
About the Position
As a Machine Learning Engineer at Phantasma, you'll work on the core AI behind AiPS, our production scheduling software. You'll develop and improve our reinforcement learning agents, work on the Digital Twin environments they train in, and help turn complex manufacturing problems into models that work in real factories.
You'll have a lot of ownership over how we approach these problems and work closely with both our engineering team and customers.
Responsibilities
- Write robust, scalable, and production-ready Python code
- Provide code reviews, guidance, and mentorship to fellow developers to maintain high coding standards
- Write unit and integration tests using tools such as unittest and pytest
- Design, engineer, and optimize features in the Digital Twin for reinforcement learning simulations using Python, NumPy, and Pandas
- Create, optimize, and maintain training and evaluation scripts for RL agents
- Set up and maintain Python environments using modern tools such as uv and conda
- Work collaboratively using Git and GitHub
- Participate in customer calls to understand requirements and translate them into actionable technical features
- Brainstorm and develop ideas to improve the RL agent, including algorithms, reward functions, and architecture
Requirements
Must Haves:
- Background in Computer Engineering, Mathematics, Machine Learning, Industrial Engineering, or a related field
- 5+ years of Python experience
- 2+ years of experience in factory shopfloor operations as an engineer or planner, or 2+ years of experience with ERP/MES systems for factories
- Strong understanding of manufacturing processes across different environments, including discrete manufacturing, line production, and engineer-to-order
- Basic understanding of reinforcement learning and experience developing or applying RL algorithms
Nice to Haves:
- 3+ years of experience in factory shopfloor operations as an engineer or planner, or 3+ years of experience with ERP/MES systems for factories
- Research experience developing RL algorithms
- Experience with CI/CD pipelines, particularly GitHub Actions
- Experience using libraries and tools such as PyTorch, Optuna, and MLflow
We Offer
