Senior Data Scientist (RL)

Joining Razer will place you on a global mission to revolutionize the way the world games. Razer is a place to do great work, offering you the opportunity to make an impact globally while working across a global team located across 5 continents. Razer is also a great place to work, providing you the unique, gamer-centric #LifeAtRazer experience that will put you in an accelerated growth, both personally and professionally.

Job Responsibilities :

This role will focus on designing and developing advanced Reinforcement Learning (RL) driven solutions for game developers and players. The ideal candidate will have deep expertise in RL algorithms, agent-based modeling, and scalable training frameworks to create intelligent gameplay agents and adaptive in-game behaviors. This role involves working closely with AI engineers, game developers, and software engineers to build cutting-edge AI capabilities that enhance exploration and fast iteration in production environments.

Essential Duties and Responsibilities

• Design and deploy reinforcement learning (RL) agents in the gaming domain to support in-house AI services. 

• Research, prototype, and evaluate RL agents with different policies and learning methodologies.

• Develop reward functions, learning strategies, and training environments aligned with gameplay objectives.

• Optimize agent performance through hyperparameter tuning, reward shaping, and model architecture refinement. 

• Generalize RL agent solutions to scale across various game engines and games spanning multiple genres. 

• Incorporate state, event, and perception signals into RL observation spaces.

• Evaluate agents using task success metrics, stability, sample efficiency, and convergence behavior.

• Analyze agent failures and debug training instabilities or policy collapse.

• Collaborate with cross-functional teams (engineers, developers, researchers) to integrate RL gameplay agents seamlessly into games. 

• Document training pipelines, assumptions, and evaluation results.

Qualifications

• Proficiency in Python, experience in compiled languages like C++ / Rust is a plus. 

• Hands-on experience in PyTorch, MLX, TensorFlow, or similar reinforcement libraries.

• Solid understanding of policy-based, value-based, and actor-critic methods.

• Experience with reward design and exploration strategies.

• Familiarity with simulation environments or gaming frameworks (e.g., OpenAI Gym, Unity, Unreal Engine). 

• Experience designing state representations, observation spaces, and action abstractions.

• Strong analytical and problem-solving skills. 

• Excellent written and verbal communication skills across technical and non-technical teams.

Preferred
 

• Experience with multi-agent RL, self-play, or adversarial training.

• Exposure to offline RL, imitation learning, or hybrid approaches.

• Experience with messaging and communication technologies such as RabbitMQ, gRPC, REST APIs for service integration.

• Familiarity with experiment tracking, reproducibility, and evaluation tooling.

Education & Experience

• Master’s or PhD in a relevant field (Computer Science, AI, Machine Learning, etc.).

• 2+ years of applied experience in reinforcement learning (academic or industry).

Travel Requirements

Role based in Singapore office, with occasional travel (up to 1 trip per year) for conferences, research collaborations, or business meetings.
