Founding ML Engineer

Overview About TRACE We're building agentic recommerce. Today, buying something means taking all of the risk. You spend money, hope you'll still want it later, and if you decide to sell it, you're stuck doing the work yourself. We think ownership should be liquid. We're building a future where intelligent systems coordinate demand, supply, pricing, and transactions automatically, giving every purchase a clear path to resale and eventually a guaranteed exit. TRACE is the first step toward that future. Today, users can list what they plan to sell before they buy it. Buyers bid, demand forms instantly, and purchases can start paying for themselves before checkout. Why join now Momentum is building quickly. We launched 2 months ago Early engagement metrics are outperforming marketplace benchmarks by 4-5x We closed a $3M seed round last month and are venture-backed We're a two-founder team based in NYC Our technical CEO spent five years as a Senior Engineer at Etsy and built the first version of TRACE herself We recently graduated from Harvard Business School Now we're building the intelligence layer that powers what's next. The role You'll be one of our first engineering hires and the person helping define how machine learning and AI shape the future of TRACE. You'll work directly with the founders and own systems end-to-end, from data infrastructure to models to production systems. This is an opportunity to help build a category-defining company from the earliest days. The core problem is simple to describe and difficult to solve: How do you match a buyer to an item that hasn't even been purchased yet, and do it accurately enough that people trust the result? TRACE sits on a unique dataset: demand before ownership. Every bid, save, search, listing, and transaction creates signals about intent, demand, pricing, and future supply. Your job is to turn those signals into products. You'll help build: Matching systems that connect buyers with future supply Demand prediction and marketplace intelligence Ranking, recommendation, and search systems AI-powered listing creation Production ML systems that directly impact user experience Feedback loops that improve with every transaction Long-term agentic systems that coordinate buyers, sellers, pricing, and transactions We're looking for someone who enjoys ambiguity, likes owning the full stack from data to production, and gets excited by hard problems that don't have obvious answers. You're probably a fit if You've shipped ML systems into production You enjoy owning the entire system, not just the model AI tools are part of your daily workflow Ambiguous, unsolved problems excite you You're interested in recommendation systems, matching, search, marketplaces, or agentic systems You want to work closely with product, design, and users Logistics NYC preferred.
