PIXIE is a new agentic AI platform that routes natural-language planning questions to specialist agents, generates trustworthy data-grounded answers, and automates business narratives - all serving analysts across Amazon's supply chain and finance organizations. We're hiring an SDE-II to own core platform subsystems in a greenfield, high-ambiguity environment where your architectural decisions ship to production within weeks. - You'll design and build production systems at the intersection of LLMs, multi-agent orchestration, and large-scale data retrieval - You'll work on novel problems: agentic routing with confidence calibration, stochastic evaluation, and authorization-aware knowledge retrieval - You'll ship visible impact - PIXIE is LTPF's flagship AI investment with VP-level visibility and direct analyst adoption metrics - Tight engineering team (8 SDEs), high autonomy, rapid iteration cycles Key job responsibilities - Design, build, and operate core platform services for PIXIE's agentic AI system - including agent runtime, caching/cost-latency optimization, observability, and evaluation infrastructure - Build and maintain the tool/agent registry that enables new capabilities to be discovered and invoked without redeployment - Develop automated evaluation and regression harnesses for non-deterministic LLM outputs - hallucination detection, drift monitoring, and faithfulness scoring - Implement authorization-aware retrieval ensuring users never see content they aren't entitled to - Collaborate with Scientists on grounding methodology, causal analytics productionization, and retrieval-quality optimization - Operate what you build - on-call rotation, runbooks, operational dashboards, and continuous improvement of system reliability - Mentor teammates on system design, code quality, and operational best practices About the team Long Term Planning and Forecasting (LTPF) owns the models, systems, and tools that power Amazon's long-range demand planning - the forecasts that drive billions in inventory, capacity, and capital decisions. PIXIE is LTPF's AI-native platform: a conversational intelligence layer that lets analysts ask questions in natural language and get trustworthy, data-grounded answers backed by Amazon's planning data. We're a small engineering team building from zero to production. Our stack spans multi-agent orchestration, retrieval-augmented generation, causal inference, and automated business narrative generation. We operate like a startup inside Amazon - fast iteration, high ownership, direct customer feedback loops - with the backing of Amazon-scale data and infrastructure. We value builders who thrive in ambiguity, care deeply about correctness (especially when LLMs are involved), and want to shape the architecture of a system from its earliest days. If you've been looking for a role where you can combine distributed systems engineering with the frontier of applied AI - and see your work used by thousands of planners across Amazon - this is it. ## Related Videos - [The Software Engineer 2030: From Coder To AI Orchestrator? - Patrick Schnell](https://www.wearedevelopers.com/videos/1825-the-software-engineer-2030-from-coder-to-ai-orchestrator-patrick-schnell) - [Are Code Reviews Worth It?
