## Job description

## SENIOR SOFTWARE ENGINEER – AI PLATFORM

NegotiateAI (Menlo Ventures–backed)

## 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.

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 ROLE

This 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 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

## MUST HAVES

- 6+ years of professional software engineering experience
- Strong backend experience building APIs and data pipelines; comfort working across the stack
- Experience shipping products in fast-moving startup or startup-like environments
- Hands-on experience with Node.js and React
- Practical 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 quality
- Strong product and design sense and ability to balance speed with correctness
- Ownership mindset: you see problems through to completion
- Full tech stack + ML + product sense must. Can code and iterate quickly and scrappily, but can also step back and architect the stack, experience with Node & React.
- A+ player, exceptionally good technically, exceptional leader
- Hungry to build a $B+ VC backed AI enterprise solution

Additional nice to haves:

- Some large company experience early in career
- Experience with building consumer software and familiar with how to build consumer-grade software
- Experience in scaling and working with enterprise clients

## About NegotiateAI

## Company Overview
- **One-liner**: NegotiateAI provides AI-powered agents that autonomously negotiate and optimize industrial procurement for manufacturers.
- **Entity Type**: Private (Accelerator/Incubator-backed, backed by Menlo Ventures)

- **Founders**: Dominic Toselli (Founder & CEO)

## Core Business
- **Primary industry/industries**: Manufacturing procurement, supply chain software, AI-driven spend management
- **Target customers**: B2B – industrial and manufacturing companies with complex, fragmented procurement spend (especially MRO categories)
- **Mission or purpose statement**: “NegotiateAI replaces the manual procurement grunt work while giving you procurement intelligence. Your AI agents never stop negotiating.”

## Products & Services
- **AI Negotiation Agents**: Autonomous agents that conduct thousands of parallel negotiations with vendors, benchmark prices, and secure better deals. They update systems and notify stakeholders instantly.
- **Procurement Intelligence Platform**: Structures invoice data, highlights overpayment, surfaces identical parts priced differently, and automates vendor follow-ups, PO tracking, catalog updates, and RFXs.
- **ERP Data Unification**: Cleans and normalizes Purchase Order and invoice data across multiple ERP systems into a single Digital Twin Spend Database.

## Market Standing
- **Valuation/Market Cap**: Not publicly available (early-stage, backed by Menlo Ventures)
- **Key Metric**: Total Funding – accelerated/incubator-backed; no disclosed amount. Customers report $10M YoY savings, 30X ROI, 80% increased efficiency.
- **Notable Investors/Partners**: Menlo Ventures (lead investor), Procurement Leaders (partnership), featured at MX.0 Manufacturing, ProcureCon MRO events.
- **Growth Signals**: +150% YoY headcount growth (4 employees as of recently, growing to ~10); active job postings for Senior AI Platform Engineer and Founding Agentic AI Product Engineer; LinkedIn followers grew 185.9% yearly.

## Competitive Advantages
- **Autonomous 24/7 Negotiation**: AI agents work tirelessly, conducting parallel negotiations that human buyers cannot match at scale.
- **Instant Implementation & ROI**: Customers see positive ROI within the first month; the tool automatically updates ERP systems upon closing a deal.
- **Deep Industry Focus**: Purpose-built for manufacturing procurement (especially MRO), handling fragmented ERP data and inconsistent benchmarks.
- **Enterprise Security**: SOC 2 certified, GDPR compliant, end-to-end encryption.

## Strategic Focus
- **Scaling the platform**: Adding features driven by customer feedback (e.g., “nimble” feature additions to fix real-world problems).
- **Expanding hiring**: Actively recruiting senior engineers and product talent to build the agentic AI platform.
- **Market penetration**: Targeting “rigorous manufacturers” and global supply chain teams, with a strong presence at industry conferences (MX.0, ProcureCon, MRO 2025).

## Why Work Here
- **Small, high-impact team**: With only ~4 employees and ambitious growth, every hire has outsized ownership and direct impact on product and culture.
- **Cutting-edge AI stack**: Work with modern tools (React, Python, TypeScript, Postgres, Databricks, Palantir, Coupa, Oracle) and agentic AI frameworks.
- **Backed by top-tier VC**: Menlo Ventures provides resources, network, and credibility.
- **Flexible environment**: Open positions are likely remote-friendly (engineering roles listed without location constraints). Culture described as “nimble” and driven by solving real supply-chain pain points.
- **Transparent growth**: CEO active on LinkedIn sharing company milestones – strong mission-focused leadership.
