Amazon's AAIS group is hiring a Principal Applied Scientist in Seattle, on-site, to set the scientific direction for AI that models how a team works, not just one person's memory. The role spans knowledge representation, temporal reasoning, retrieval, proactive agent behavior, evaluation, synthetic data and model efficiency. It asks for a PhD or a master's with 8+ years, 10+ years shipping ML systems, LLM depth plus two listed specialisms, and Python. Scientists here own capabilities end to end, working against real usage rather than benchmarks alone.
