About NegotiateAI NegotiateAI is building an enterprise AI platform to modernize procurement for manufacturing and industrial companies. Procurement today is fragmented, manual, and opaque. We’re changing that by giving teams clean data, real‑time visibility, and AI‑driven workflows that actually get used.

About the Role This is a

hands‑on senior execution role

working alongside the founding engineers. You’ll help build and scale the core platform across backend services, AI workflows, and the Buyer Portal frontend. You’ll be expected to move fast using contemporary AI‑assisted development tools (e.g., Cursor, Copilot‑style workflows) to iterate quickly, refactor aggressively, and ship production‑quality code. This is not a research role – it’s about building systems that work.

What You’ll Do

Build and extend backend services that power NegotiateAI’s AI‑driven procurement platform

Implement LLM‑ and RAG‑based pipelines for spend categorization, benchmarking, and supplier analysis

Develop and maintain agentic workflows that automate analysis, recommendations, and follow‑ups

Contribute to the Buyer Portal frontend (React), building clean, usable interfaces for procurement teams

Use AI‑assisted coding tools (e.g., Cursor) to accelerate development, debugging, and iteration

Integrate with customer data sources (ERPs, invoices, supplier files) and handle messy, real‑world datasets





Collaborate closely with the founding engineer on architecture, trade‑offs, and execution

Write clear, maintainable code with strong attention to performance, reliability, and observability
