Founding ML Engineer, Computer Vision (Object Detection)

About the role Moe’s entire pitch to users rests on one claim: we can identify any item in the world from a photo and price it as accurately as a human expert, instantly. You’ll build the model that makes that claim true. This isn’t a research exercise — every category you get right becomes a category users trust Moe with real money, and every one you get wrong becomes a support ticket and a churn risk. You’ll set the technical direction for identification from day one, with real ownership over architecture, data strategy, and the accuracy bar we hold ourselves to. What you’ll do Design and own the computer vision architecture for fine-grained item identification — brand, model, edition, variant — starting from foundation vision models and fine-tuning toward Moe’s specific catalog Define what “accurate enough” means per category, and build calibrated confidence scoring so the product can say “we’re not sure” instead of guessing Build the feedback loop between model errors and what gets labeled next, in partnership with the labeling lead Decide where to invest: broader category coverage vs. deeper accuracy on today’s categories Own the model serving path from research to production — latency, cost, and reliability at scale Represent the identification model’s capabilities and limits to the rest of the company, including in investor and customer conversations when needed What we’re looking for 5+ years in applied computer vision, with at least one system shipped to production at meaningful scale Hands-on experience with fine-grained/instance-level classification, not just general object detection — you’ve worked on a problem where “close” isn’t good enough (e.g., telling two similar sneaker colorways or watch references apart) Strong fluency in PyTorch or TensorFlow, and experience fine-tuning and deploying vision transformers or CNNs in production Experience designing and running evaluation frameworks for vision models — you know how to measure whether a model is actually getting better, not just achieving a lower loss Comfortable being the most senior technical voice on a hard, open-ended problem with no existing internal playbook Strong written and verbal communication — you’ll need to explain technical tradeoffs to non-technical stakeholders, including investors Nice to have Prior work at a resale/marketplace company (StockX, GOAT, Vinted, Rebag, The RealReal) or a visual search company (Pinterest Lens, Google Lens, Syte) Experience with active learning or human-in-the-loop labeling pipelines Familiarity with deploying models behind low-latency APIs at scale Founding or early-stage startup experience, ideally as the first ML hire What success looks like 30 days: fully ramped on the current state of the identification problem; has picked the first category to ship (e.g., sneakers or watches) and defined the accuracy bar for it 60 days: v1 identification model is live for that category, with a measured accuracy baseline against a held-out test set 90 days: confidence scoring is in place, and there’s a clear, prioritized plan for expanding into the next 2–3 categories Process Intro call → technical deep dive on a past project → a scoped take-home or pairing session on a real Moe identification problem → founder conversation.
