Senior Software Engineer (SDE3) — Data & Intelligence Platform
This isn't a role where you'll spend your days in a narrow lane.
The work is genuinely varied: one week you're designing a data API, the next you're improving retrieval quality in a RAG pipeline, the next you're working with infrastructure to get a service into production. We're looking for someone who finds that energising rather than uncomfortable.
Data platform - a high-performance service that brings together multiple data sources - analytical, caching, vector, and object stores - behind a clean typed API. Supply chain data is high-volume and time-sensitive; getting the data layer right underpins everything else the platform does.
Intelligence layer - we work closely with forecasting teams across the business who produce demand signals, predictions, and recommendations. Our job is to make that intelligence accessible, actionable, and explainable - surfacing it through well-designed APIs, keeping it fresh, and ensuring the right data reaches the right place at the right time.
LLM integration - a conversational and tool-calling layer that gives supply chain teams natural language access to platform data and forecasts. You'll work on retrieval quality, tool design, prompt architecture, and streaming response pipelines. This is a relatively new area for us and there's genuine room to shape how it evolves.
Kubernetes and cloud-native deployment experience is useful. So is supply chain or forecasting domain knowledge. Neither is required.
The work is meaningful The platform influences ordering decisions across thousands of stores. When it works well, products are on shelf. When it doesn't, they aren't. That directness of impact is something most engineering roles don't offer.
