With the right tools and insights, we believe that we can level the playing field so businesses can grow and local communities can thrive.
We’re looking for smart, resourceful and passionate people to join us as we power the shop local movement. If you believe in community, come join ours.
Data Science Internship — Multiple Teams
Faire leverages machine learning and data insights to transform the wholesale industry, giving independent retailers the tools to compete with large-scale e-commerce platforms and big-box stores. Our Data Science team builds and maintains the algorithmic systems — spanning search, personalization, recommendation, and ranking — that power our marketplace and help our customers thrive.
We are hiring Data Science interns across several teams and are looking for intellectually curious, self-directed problem solvers eager to work end-to-end on high-impact challenges, from data exploration to production-ready solutions.
Our internships are paid, 12–14 weeks in duration, with flexible start dates. Extensions are considered based on project scope and mutual interest.
Open Teams
Search & Recommendation
- Design and deploy state-of-the-art recommender systems that power ranking and discovery across the marketplace
- Develop rich user and item representations through embeddings, sequence models, and graph-based methods
- Build real-time and streaming data pipelines that enable dynamic, context-aware personalization at scale
- Apply exploration–exploitation strategies — including contextual bandits and reinforcement learning — to optimize recommendations under uncertainty
- Advance recommendation quality through improvements to diversification, novelty, and long-term user engagement
- Own the full ML lifecycle: from problem formulation and modeling through offline evaluation and online experimentation
Fulfillment
- Develop ML models that predict product demand for brands leveraging Faire's fulfillment services, informing replenishment decisions, reducing stockouts, and improving inventory reliability across the platform
- Apply machine learning and optimization techniques to enhance the efficiency of Faire's fulfillment operations, including inventory placement, order packing logic, and operational workflow improvements
- Collaborate with the Discovery team and internal stakeholders to optimize surfaces that promote fulfillment products to retailers, driving discoverability and supporting the growth of Faire's fulfillment offering
Risk Management
- Build and refine models and heuristics across core risk domains — including underwriting, identity verification, returns, markdowns, and disputes & misuse — to reduce financial losses and unlock GMV growth
- Partner cross-functionally to develop scalable, data-driven frameworks that balance risk exposure with business opportunity
What You'll Do
- Design, develop, and A/B test cutting-edge machine learning algorithms and analytical solutions, with guidance from senior technical leads
- Communicate project objectives, methodologies, and results clearly to both immediate teammates and broader cross-functional stakeholders
- Navigate the complexity of a two-sided marketplace, identifying and addressing the unique challenges that arise at the intersection of retailer and brand needs

- Familiarity with offline evaluation metrics (NDCG, MAP, recall) and online experimentation
- Experience working with large-scale or production datasets
Fulfillment
- Experience with Python; familiarity with Java, Kotlin, or C++ is a plus
- Production-level experience building and deploying ML systems
- Working knowledge of statistical methods, including experimentation and causal inference
- Experience with SQL or other query languages preferred
- Genuine enthusiasm for tackling ambiguous problems and learning new tools and techniques
Risk Management
