Design a Visual Search Backend for a Boutique Luxury Marketplace
Overview
What this challenge is about.
Design a Visual Search Backend for a Boutique Luxury Marketplace. Advanced challenge in code. Writing production code that solves real engineering problems, ...
The Brief
What you'll do, and what you'll demonstrate.
Ship a visual-search backend with recall@12 above 0.7 on the labeled query set and p95 latency under 200 ms.
This is not a coding exercise. It is the work a software engineer does between a Jira ticket and a merged PR. That distinction matters to every hiring manager who has seen candidates solve LeetCode problems and none who have shipped production code under real constraints.
When you finish, you will have something most graduates do not: a real-world deliverable, verified by Ewance, that you can show to a hiring manager and say "I did this. Here is the proof."
Earning criteria — what you'll demonstrate
- Select and evaluate vision embedding models for retrieval
- Operate a vector index at catalog scale
- Measure retrieval quality with recall@k and qualitative review
- Communicate retrieval-quality limits to a non-technical merchandising audience

Careers
Career paths this challenge builds toward
Completing this challenge demonstrates skills that transfer directly to these roles:
Machine Learning Engineer
Owning a visual-search backend end-to-end is a canonical MLE deliverable at marketplaces and e-commerce companies.
This challenge sharpens
- visual-search
- embeddings
- vector-search
Computer Vision Engineer
Tuning vision embeddings for catalog retrieval is increasingly a CV-engineer specialization at marketplaces.
This challenge sharpens
- embeddings
- clip
- retrieval-evaluation
AI Engineer
Standing up the retrieval API plus the metadata pre-filter and the merchandising brief is exactly the bundle AI engineers ship at small product teams.
