Senior Software Engineer – AI PlatformNegotiateAI (Menlo Ventures–backed)About NegotiateAINegotiateAI 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.We focus on indirect spend - MRO, services, and long-tail categories - where inefficiency quietly costs enterprises millions every year. Our platform combines agentic AI, LLMs, and Retrieval-Augmented Generation (RAG) to turn messy procurement data into actionable decisions and measurable savings.Backed by Menlo Ventures and founded by a former Apple supply-chain leader, we’re building real systems used by real enterprises.About the RoleThis is a hands-on senior execution role working alongside with 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 modern 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 DoBuild and extend backend services that power NegotiateAI’s AI-driven procurement platformImplement LLM- and RAG-based pipelines for spend categorization, benchmarking, and supplier analysisDevelop and maintain agentic workflows that automate analysis, recommendations, and follow-upsContribute to the Buyer Portal frontend (React), building clean, usable interfaces for procurement teamsUse AI-assisted coding tools (e.g., Cursor) to accelerate development, debugging, and iterationIntegrate with customer data sources (ERPs, invoices, supplier files) and handle messy, real-world datasetsCollaborate closely with the founding engineer on architecture, trade-offs, and executionWrite clear, maintainable code with strong attention to performance, reliability, and observabilityMust Haves6+ years of professional software engineering experienceStrong backend experience building APIs and data pipelines; comfort working across the stackExperience shipping products in fast-moving startup or startup-like environmentsHands-on experience with Node.js and ReactPractical experience building or integrating AI-powered systems (LLMs, RAG, embeddings, or agentic workflows)Comfortable using AI-assisted development tools (Cursor, Copilot, or similar) to move faster without sacrificing qualityStrong product and design sense and ability to balance speed with correctnessOwnership mindset: you see problems through to completion Full tech stack + ML + product sense must.
