Senior Machine Learning /AI Engineer (RL) @ Acaisoft

• 6+ years of experience in Python software engineering.
• Minimum 3 years in a Machine Learning/Environment Engineering, Data Scientist position.
• Practical knowledge of AI frameworks (Langchain, Langraph, mcp-server ).
• Extensive practical experience in working with AI, including prompt engineering and vibe coding.
• Experience in working with business requirements (analysis, summarizing, responding to changes).
• Expertise in planning your own work or that of a small team. 
  

Nice to have:

• Knowledge of Codex or Claude Code.
• Experience in integrating AI with a system would be an advantage.
• Understanding of RL concepts - reward modeling, environment dynamics, verifiability, evaluation, and agent interaction loops.
• Familiarity with instrumentation, metrics, and data pipelines for RL evaluation.

You will be cooperating with a leading provider of AI evaluation and optimization solutions, trusted by multinational companies to optimize AI agents and detect performance issues in large language models.
In this role, you’ll help develop advanced reinforcement learning (RL) environments and scalable evaluation systems that guide and shape the behavior of cutting-edge AI models. The company’s mission is to enable safe, verifiable, and aligned AGI through rigorous, real-world agent evaluation.

Due to the client’s time zone, we would appreciate a candidate who can work 12 p.m. - 8 p.m.

This is a 100% remote position, but if you enjoy working from an office, you’re warmly welcome to join us there too ?

 Join us and make a real impact! 

If you’re ready to broaden your horizons and work with an innovative company at the forefront of AI, we’d love to hear from you. You’ll help build the environments that shape how future AI systems are trained, evaluated, and aligned - and collaborate with world-class engineers and researchers on one of the most important technical challenges of our time.
