Role description
Are you passionate about Reinforcement Learning (RL) and ready to make an impact in real-world projects? Join our team as an RL Engineer to contribute to groundbreaking advancements in artificial intelligence and machine learning. Weβre looking for someone with hands-on expertise in RL, a proven ability to lead innovative projects, and a desire to push technological boundaries.
About the Role:
β’ Apply RL concepts to real-world challenges, leveraging your expertise in environment-agent dynamics, reward mechanisms, and policy optimization.
β’ Lead development, implementation, and optimization efforts for RL models, preferably on platforms like AWS SageMaker.
β’ Collaborate across teams to expand RL solutions into new domains and refine existing systems.
β’ Develop and articulate reward functions to optimize agent performance.
β’ Document design decisions and communicate RL strategies effectively to technical and non-technical audiences alike.
Responsibilities:
β’ Proven experience applying RL principles in complex, real-world projects.
β’ Expertise with AWS SageMaker (or similar platforms) for ML development/deployment.
β’ Deep understanding of RL core concepts, algorithms (like PPO, DQN, Actor-Critic), and frameworks.
β’ Operational know-how in RL model deployment, CI/CD pipelines, and experimentation workflows.
β’ Strong problem-solving skills and ability to lead cross-functional collaborations.
