At Phantasma Labs, we’re building smart software that helps factories plan better. Our AI co-pilot helps factories schedule production more efficiently, adapt to changes faster, and make the most of available resources, without needing tons of data or complicated tools. Instead of relying on massive historical datasets, our models are trained in simulated factory environments using reinforcement learning, which helps us find better solutions much faster than traditional systems. We work with manufacturers across Europe and the US and team up with ERP and MES providers to bring our solution directly into real production workflows. We’re based in Berlin, but remote-first, so you don’t have to be here to join us. We’re a lean, international team with big ambitions, building what we believe is one of the most advanced production planning tools in the world.
Tasks
- Write robust, scalable, and production-ready Python code
- Provide code reviews, guidance, and mentorship to fellow developers to maintain high coding standards
- Write unit tests and integration tests (unittest, pytest, etc.)
- Design, engineer, and optimize features in the digital twin for Reinforcement Learning (RL) simulations using Python (Python data structures, NumPy, Pandas, etc.)
- Create, optimize, and maintain training and evaluation scripts (for RL agents)
- Set up and maintain Python environments using modern tools (uv, conda, etc.)
- Work collaboratively using git (GitHub)
- Participate in customer calls to understand and translate requirements into actionable technical features.
- Brainstorm ideas to improve the RL agent, including algorithms, rewards, and architecture.
Requirements
