Applied ScientistRl Engineer

As an Applied Scientist on the Science SW team, you will collaborate closely with other scientists and engineers to bring Reinforcement Learning (RL) research to production. This role combines the scientific application of ML
specifically RL and sequential decision making, with software development engineering and a strong product focus. It will be your job to design, implement
deploy novel RL agents, reward models
control policies in both prototype and production environments
to prove their impact in high-fidelity simulation before scaling them across the fleet. Key job responsibilities
Own the research and development of reinforcement learning and sequential decision making solutions spanning deep RL, policy optimization, offline/batch RL, contextual bandits
multi-agent RL for real-time MHE control and building-wide optimization in a production environment.
Formulate fulfillment operations problems (throughput optimization, flow, merge
congestion control) as sequential decision-making problems
design multi-objective reward functions that balance competing operational objectives.
Build and leverage high-fidelity simulation environments for safe offline training, policy validation, and sim-to-real transfer before fleet-scale deployment.
Collaborate across multiple science and engineering teams to integrate RL policies into real-time production and control systems. About the team Amazon is building next generation software, hardware
processes that will run our global network of fulfillment centers that move millions of units of inventory
ensure customers get what they want when promised. The Science Software team in the One MHS organization unlocks Material Handling Equipment (MHE) innovation through a multiplicity of disciplines within Artificial Intelligence (AI) and applied science, including Computer Vision (CV), Physics-Informed Neural Networks (PINNs), Optimization, Reinforcement Learning, classical Machine Learning, statistical modeling
sensing-hardware prototyping. Rooted in first principles aligned experimentation, the team is dedicated to building self-optimizing fulfillment centers, developing the models that drive real-time, building-wide orchestration of MHE. We conduct experiments, develop models
apply machine learning (ML) at scale to optimize throughput, flow, merge
to improve operational performance across the fulfillment network.
PhD in computer science, machine learning, engineering, or related fields - 2+ years of building machine learning models or developing algorithms for business application experience - Demonstrated experience developing and applying reinforcement learning and sequential decision-making methods (e.g., deep RL, policy gradient / actor-critic methods, offline RL, contextual bandits, or multi-agent RL) to real-world control or optimization problems. - Fluency in a high-level programming language such as Python
experience with C++ is a plus. - Experience with popular deep learning frameworks (e.g., PyTorch, TensorFlow) and RL tooling or simulators (e.g., Ray/RLlib, Gymnasium, Stable-Baselines3, Isaac Gym/Omniverse, MuJoCo). - Ownership of end-to-end solutions in terms of research, prototyping, and experimentation.
First-author publications at top-tier machine learning and AI venues (e.g.,NeurIPS, ICML, ICLR, AAAI, AISTATS, CoRL
RLC/RLDM). - Experience applying RL in a setting analogous to ours: real-time control, robotics or material handling, industrial process or operations. - Experience deploying RL or ML models to production at scale and partnering with engineering teams on real-time inference and feedback loops.
