Senior Applied AI Engineer | Series A AI Startup

Job Description

Senior Applied AI Engineer – New York, NY (On-site) | Series A AI Startup | $220k – $300k+ & Equity
Most AI products are thin wrappers on someone else’s model. This one is built on proprietary data that no foundation model has access to.

We’re working with a Series A AI company building the operating system for independent retail. Its platform runs the whole business, including point of sale, eCommerce, payments, payroll and wholesale purchasing, which means it holds a uniquely complete picture of each business: in-store and online sales, supplier buying patterns, staffing costs and financial data, all in one place.

That data is the moat, and the AI team’s job is to turn it into agents that run a store.

Proprietary, cross-channel data. You’ll work with real operational data from a growing network of businesses, not public benchmarks.
Your work goes live with real businesses the same week, and customers tell you directly whether it made them money.
AI-native engineering. Agentic coding tools are core to how the team works, and engineers here ship a multiple of what they would elsewhere.

Detecting theft and costly operational mistakes from patterns across sales, staffing and inventory data
Reading messy real-world supplier documents and turning them into structured data that drives inventory and payments
Building the evaluation systems that prove each agent actually improves revenue and saves time

5+ years building and shipping AI/ML products in production
~ Bonus: post-training/fine-tuning open-source models, retrieval/ranking, forecasting or pricing experience

Meaningful early-stage equity
Fully covered medical and dental, 401(k)
Fully on-site in New York, working alongside the founding team
