Our inspiration

Building on the formulation of Maxwell’s equations in 1865, Heinrich Hertz demonstrated in 1888 that radio waves can be generated, transmitted, and detected in a laboratory setting. Though Hertz doubted this discovery would lead to any practical application, it provided the game-changing experimental results that inspired Guglielmo Marconi to develop a viable radio system, transmitting the first signals across the Atlantic Ocean in 1902.

It took fourteen years from an important experimental observation by Hertz until the radio became widespread. Now, we are interested in identifying key scientific findings since the year 2000 and working with big thinkers who can help foster their development into engineered products and services at a much faster pace. We aim to identify the modern-day equivalents of the Hertz experiment.

We are looking for a passionate Applied Scientist to contribute to the next generation of agentic AI applications for Amazon advertisers. In this role, you will support the development of agentic architectures, help build tools and datasets, and contribute to systems that can reason, plan, and act autonomously across complex advertiser workflows. You will work alongside senior scientists at the forefront of applied AI, gaining hands-on experience with methods for fine-tuning, reinforcement learning, and preference optimization, while contributing to evaluation frameworks that ensure safety, reliability, and trust at scale. You will work backwards from the needs of advertisers—contributing to customer-facing products that directly help them create, optimize, and grow their campaigns. Beyond building models, you will support the agent ecosystem by experimenting with and applying core primitives such as tool orchestration, multi-step reasoning, and adaptive preference-driven behavior. This role involves tackling well-scoped technical problems, while collaborating with engineers and product managers to bring solutions into production. Key Job Responsibilities - Contribute to building agents that guide advertisers in conversational and non-conversational experiences. - Implement model and agent optimization techniques, including supervised fine-tuning, instruction tuning, and preference optimization (e.g., DPO/IPO) under guidance from senior scientists. - Support dataset curation and tool development for MCP. - Contribute to evaluation pipelines for agent workflows, including automated benchmarks, multi-step reasoning tests, and safety guardrails. - Implement and iterate on agentic architectures (e.g., CoT, ToT, ReAct) that integrate planning, tool use, and long-horizon reasoning. - Support prototyping of multi-agent orchestration frameworks and workflows. - Collaborate with peers across engineering, science, and product to bring scientific innovations into production. - Stay current with the latest research in LLMs, RL, and agent-based AI, and apply findings to practical problems.
