About The Position

Daydream is the first chat-based shopping agent built exclusively for fashion. Designed to redefine how people search and discover fashion, Daydream offers a personalized, conversational experience powered by advanced AI and natural language understanding.
Backed by top-tier investors including Forerunner Ventures, Index Ventures, Google Ventures, and True Ventures, our team is committed to shaping the future of shopping.
As the Engineering Lead, Platform & AI, you'll own multiple backend systems at Daydream: the catalog data pipeline that powers our product index, the AI content pipeline that builds landing pages for ad campaigns, and the B2B integration layer that puts our search on partner retail sites. The work is mostly Python and Go, involves a lot of LLM integration, and what you build shows up directly in the product.

Requirements

• You have a strong backend engineer with production Python experience. Go is a big plus.
• You’ve done something real with LLMs: prompt engineering, multi-step workflows, output evaluation. Not just played with the API.
• You are comfortable with cloud infrastructure: GCP (BigQuery, GCS), Kubernetes, GitOps
• You have built and run systems at scale, whether data pipelines, API services, or batch processing
• You are analytical and fast. You ramp into unfamiliar code quickly and make pragmatic calls
• You use AI tools well in your own workflow
• You are self-directed, comfortable owning multiple systems without a lot of process
• Based in New York
