Director Partner Engineering Jobs in Monroe, WA (NOW HIRING)

The Fleet Performance Optimization (FPO) organization builds the intelligence layer for Amazon Robotics manipulation workcells. We own the systems that select what work a robot should attempt, monitor how it performs, and close the loop by improving models with every induct. Our platforms serve Sparrow, Cardinal, FlexCell, and Robin workcells that handle millions of packages across Amazon's fulfillment network.
We operate across the full ML and data lifecycle:
Work Selection Intelligence - Eligibility scoring and predictions (likelihood-to-empty, damage prediction, time-to-process, pick eligibility) that feed into work planners, identifying which totes and items reach each workcell.
Data & Observability - A common datalake collecting telemetry from every automated and manual workcell, fleet monitoring that detects performance degradation in real time and alerts Ops, and deep-dive tooling that enables engineers and scientists to investigate workcell behavior.
ML Lifecycle - Annotation orchestration, model training pipelines, production monitoring, and deployment infrastructure that keeps models current across the fleet.
Predictive Models - Science-developed foundational models applied to eligibility, fleet performance forecasting, and dynamic floor policies that adapt to changing conditions without manual intervention.
Our systems process tens of millions of events daily, serve real-time scoring at workcell-runtime latency, and directly impact fulfillment cost per unit

Key job responsibilities
As an SDE on FPO, you will design, build, and operate distributed systems that sit at the intersection of robotics, machine learning, and large-scale data processing. You will work closely with scientists, program facilators, and partner engineering teams to translate research into production systems that operate reliably at fleet scale.
Depending on the team, your work may include:
- Building high-throughput, event-based scoring services that process real-time inventory signals across 10+ warehouses and hundreds of workcells
- Designing config-based annotation orchestration systems that onboard new ML data pipelines without code changes
- Developing model deployment infrastructure spanning edge devices, cloud inference services, and planning systems
- Building fleet monitoring systems that use VLMs and statistical methods to detect performance anomalies and surface root causes
- Creating unified data exploration and visualization tools used daily by engineers, scientists, and operations
- Implementing ongoing learning systems that intelligently select which data to collect based on inference outcomes
- Extending our foundation models, which are the backbone for multiple prediction tasks
- Own your systems end-to-end - from design through production operations - and your work will have direct, measurable impact on workcell throughput, quality, and cost.

About the team
Why FPO?
Impact at scale - Your code runs on hundreds of workcells processing millions of packages. Improvements compound across the fleet.
Science meets engineering - You work alongside ML scientists and translate their research into production systems

You don't just deploy models, you build the platforms that make the entire ML lifecycle faster.
Breadth of problems - From real-time scoring services to VLM-based monitoring to data platform design, the technical surface area is wide and deep.
Ownership - Small teams, high self-governance, direct line from your work to business outcomes.
