Faire

<div>About Faire
Faire is a technology wholesale platform built on the belief that the future is local. Independent retailers around the globe collectively represent a multi-hundred-billion-dollar wholesale market that has historically been fragmented and offline. At Faire, we're using the power of tech, data, and machine learning to connect this thriving community of entrepreneurs across the globe. Picture your favorite boutique in town — we help them discover the best products from around the world to sell in their stores. 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.</div>About the role
Search is how retailers do their jobs on Faire. Wholesale queries and retailer expectations look different from consumer e-commerce and the right product depends on the store's category, price point, and aesthetic. When we get it wrong, it costs real money.
The Search algorithms team owns everything between the click on the search bar and the final ranker: typeahead and empty-state suggestions, query understanding, retrieval across five-plus independent sources, relevance modeling, and result-page surfaces like carousels and refinements. Within our scope, scientists own components outright: when you own query understanding here, you own the models, the roadmap, and the metrics.
You'll work across the full modern search stack: transformer-based embedding retrieval serving live traffic, LLMs powering query understanding and query rewriting, fine-tuned vision-language models scoring relevance, and graph-based retrieval — with generative retrieval and semantic IDs on the horizon.
What you'll do
<ul>
<li>Contribute to the next-generation Search engine, integrating LLMs, query understanding, dense vector retrieval, deep personalization embeddings, multi-stage ranking, and reinforcement learning to serve personalized product feeds with &lt;100ms latency.</li>
<li>Own one or more search components end to end: problem framing, modeling, production code, experiment design, and the call on what to build next.</li>
<li>Ship to live traffic and let A/B tests, not opinions, settle what works.</li>
<li>Raise the team's bar through design reviews, pairing, and honest post-mortems</li>
</ul>
You're a great fit if you have
<ul>
<li>3+ years building production ML systems, with meaningful time in search, recommendations, or another retrieval-and-relevance domain.</li>
<li>Shipped models that served real traffic, and owned the experiments that proved (or disproved) their value.</li>
<li>Depth somewhere in the modern retrieval stack — dual encoders and ANN serving, LLM-based query understanding, learning-to-rank fundamentals — and the ability to pick up the rest. </li>
<li>Strong Python and the engineering chops to take your own models to production.</li>
<li>Clear communication with scientists, engineers, and PMs: you make a crisp case for your ideas and update quickly when someone has a better one.</li>
<li>Excellent product judgment to connect customer and business context to technical decisions</li>
</ul>
Bonus Points
<ul>
<li>Marketplace or e-commerce experience</li>
<li>Publications, open-source work, or public writing on search and recommender systems.</li>
<li>MS or PhD in CS, Statistics, or a related field.</li>
</ul>
Salary Range
Canada: the pay range for this role is $180,000 to $247,500 per year.
This role will also be eligible for equity and benefits. Actual base pay will be determined based on permissible factors such as transferable skills, work experience, market demands, and primary work location. The base pay range provided is subject to change and may be modified in the future.
Faire uses Artificial Intelligence (AI) to screen and select applicants for this position.

Senior Applied AI/ML Scientist - Retailer Growth

<div>About Faire
Faire is a technology wholesale platform built on the belief that the future is local. Independent retailers around the globe collectively represent a multi-hundred-billion-dollar wholesale market that has historically been fragmented and offline. At Faire, we're using the power of tech, data, and machine learning to connect this thriving community of entrepreneurs across the globe. Picture your favorite boutique in town — we help them discover the best products from around the world to sell in their stores. 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.</div>About the role
Faire is building the future of wholesale, connecting independent retailers with the brands that will define their stores. At the heart of this mission is Compass — Faire’s user facing AI bet within the Discovery Pillar — building an always-present, context-aware retailer assistant along the enagement journey. Compass helps retailers make smarter buying decisions by combining Faire’s rich proprietary data with agentic AI and web search, and is increasingly able to take action on retailers’ behalf.
As a Senior Applied AI/ML Scientist on the Compass team, you will be the science and technical lead for this product — driving agent quality through data, evaluation, and modeling, while shipping product features end-to-end with high velocity. This is a deeply hands-on individual contributor role: no direct reports, keyboard first. You will set the data-grounded direction for how the assistant works, while also being a full-stack (AI, ML, backend) builder who turns ideas into shipped product fast.
You will work at the frontier of agentic AI, blending applied science rigor (eval-driven development, experimentation, data strategy) with cross-stack engineering range to build the retailer assistant of the future. This is a rare opportunity to shape a product from near-zero — where your judgment, speed, and instincts will define the outcomes.
What you’ll do
<ul>
<li>Own the science and technical north star for Compass’s agentic products — the retailer assistant today and whatever comes next: how to leverage Faire’s proprietary data, agent + tool + context strategy (preload vs. tool-calling vs. hybrid), and how to measure and raise agent quality as systems gain the ability to act.</li>
<li>Ship retailer-assistant features end-to-end — across the FLARE Python app, data plumbing, tool wrappers, and the frontend surfaces where the assistant appears, using AI-native workflows to multiply your output.</li>
<li>Translate ambiguous product bets into sequenced, de-risked tactical plans — what to build now, what to defer, and which bets carry the highest impact × probability-of-success.</li>
<li>Set and raise the bar for eval- and experiment-driven development — define how the team knows an agent is good, including offline eval suites, LLM-as-judge metrics, and quality criteria per surface and retailer journey.</li>
<li>Make pragmatic engineering choices: simple enough to ship now, designed to evolve — not over-engineered for imagined future scale, but not throwaway either.</li>
<li>Partner closely with engineers on architecture and serving tradeoffs, and act as the science/technical interface to adjacent teams (Search, Personalization, Platform/FLARE).</li>
<li>Raise the team’s collective judgment through prototypes, analyses, design reviews, and pairing.</li>
</ul>
You’re a great fit if you have…
<ul>
<li>5+ years of industry experience building and shipping production ML/AI systems with measurable business impact — including hands-on ownership of the applied-science side (data, evaluation, modeling, quality), not just system plumbing.</li>
<li>Has shipped agentic / LLM-powered features in a core production product — with a deep, opinionated grasp of agent design tradeoffs: eval strategy, latency/cost/quality tension, tool-calling vs. context preload, guardrails, and failure containment.</li>
<li>Strong applied ML / data science foundation — reasons from data, designs experiments and evals, and has turned proprietary or structured data into product capability.</li>
<li>Track record of shipping fast across multiple stacks (backend, data, and ideally frontend) with quality — not a single-layer specialist; demonstrates cross-stack range.</li>
<li>AI-native in practice: uses AI coding tools and agent workflows as a force multiplier in day-to-day work.</li>
<li>Architectural maturity — can explain design choices that work simply today but won’t need to be thrown away when requirements grow.</li>
<li>Operates with high autonomy and resourcefulness, with good judgment about when to escalate and when to just solve it.</li>
<li>Fluent enough in engineering to make sound architecture calls.</li>
</ul>
Bonus points for…
<ul>
<li>E-commerce, marketplace, or two-sided platform context — understanding of both sides of the retailer/brand dynamic.</li>
<li>Experience evolving a read-only assistant into one that takes actions safely — confirm-first patterns, guardrails, and failure containment.</li>
<li>Hands-on experience with the OpenAI Agents SDK or similar agentic frameworks in production.</li>
<li>Familiarity with preload-over-RAG context strategies, Snowflake-backed grounding, or hybrid approaches.</li>
<li>Prior 0→1 / early-stage product experience — has built something meaningful from scratch.</li>
<li>Recommendation, retrieval, or personalization modeling background.</li>
<li>Public writing, open-source contributions, or talks that show structured thinking about agentic / applied-AI systems.</li>
</ul>
Salary Range

<li>Strong applied ML / data science foundation — reasons from data, designs experiments and evals, and has turned proprietary or structured data into product capability.</li>
<li>Track record of shipping fast across multiple stacks (backend, data, and ideally frontend) with quality — not a single-layer specialist; demonstrates cross-stack range.</li>
<li>AI-native in practice: uses AI coding tools and agent workflows as a force multiplier in day-to-day work.</li>
<li>Architectural maturity — can explain design choices that work simply today but won’t need to be thrown away when requirements grow.</li>
<li>Operates with high autonomy and resourcefulness, with good judgment about when to escalate and when to just solve it.</li>
<li>Fluent enough in engineering to make sound architecture calls.</li>
</ul>
Bonus points for…
<ul>
<li>E-commerce, marketplace, or two-sided platform context — understanding of both sides of the retailer/brand dynamic.</li>
<li>Experience evolving a read-only assistant into one that takes actions safely — confirm-first patterns, guardrails, and failure containment.</li>
<li>Hands-on experience with the OpenAI Agents SDK or similar agentic frameworks in production.</li>
<li>Familiarity with preload-over-RAG context strategies, Snowflake-backed grounding, or hybrid approaches.</li>
<li>Prior 0→1 / early-stage product experience — has built something meaningful from scratch.</li>
<li>Recommendation, retrieval, or personalization modeling background.</li>
<li>Public writing, open-source contributions, or talks that show structured thinking about agentic / applied-AI systems.</li>
</ul>
