About Mozart
Mozart does the work companies have with other organizations: the requests, claims, submissions and payments that go out, and the answers that must come back.
The role
You'll be the first engineer and own the product end to end: architecture, data, AI, and the experience suppliers see. You'll work directly with customers and help decide what we build next.
What you’ll own
- The data layer: connectors for remittances, retailer and distributor portals, ERPs and accounting systems, EDI, and the PDFs and spreadsheets that make up the rest
- The matching and validation engine that ties each deduction to its invoice, PO, delivery proof and trade agreement
- AI agents that classify deductions, draft disputes, and submit them through portals, with human review where accuracy matters
- The supplier-facing app: recovery dashboard, dispute queue, reporting
- Security, auditability and reliability from the start, since we handle customers’ financial data
- Hiring and setting the bar for the engineers who follow
About you
- 3+ years shipping production software, ideally at an early-stage startup
- Strong in TypeScript and/or Python, Postgres, and modern cloud tooling
- Have built with LLMs in production: structured extraction, tool use, evals
- Comfortable with messy data and unglamorous integrations
- Want to talk to customers, not just tickets
Nice to have
Fintech, AR/AP or ERP integrations; browser automation; document AI/OCR; prior founding or first-ten-engineer experience.
Details
Full-time, NYC (in person preferred).
