About the company

QXO is the largest publicly traded distributor of roofing, waterproofing, and complementary building products in the United States. The company aims to become the tech-enabled leader in the $800 billion building products distribution industry and generate outsized value for shareholders. QXO is targeting $50 billion in annual revenues within the next decade through accretive acquisitions and organic growth.

QXO is hiring an AI Engineer to design, build, and operate production-grade AI agents that power pricing, quoting, and ecommerce-driven revenue workflows across our platforms.

This is a hands-on engineering role focused on agentic systems, LLM orchestration, and real-world automation—not research prototypes. You’ll build intelligent agents that integrate with pricing engines, catalogs, CRM, and data platforms, with a direct impact on conversion, margin, and operational efficiency.

You’ll work closely with product, engineering, and GTM partners to translate complex business workflows into reliable, observable, and scalable AI-powered systems.

What you will do::

Build & Deploy AI Agents

• Design and implement AI agents using modern orchestration frameworks (e.g., LangChain, LlamaIndex, OpenAI-based ecosystems, or equivalents).
• Build tool-serving architectures (including MCP servers or equivalent patterns) to enable secure, scalable agent capabilities.
• Develop agentic workflows that perform multi-step reasoning and interact with structured and unstructured data.
• Package, deploy, and operate agents in production with a focus on reliability, performance, and observability.

Revenue, Pricing & Ecommerce Use Cases

• Build agents that support revenue-generating workflows such as:
• + Generating bills of materials (BOMs), estimates, and quotes from drawings, specs, takeoffs, or opportunity data

+ Pricing validation, margin checks, and versioned quoting

+ Enrichment and prioritization of leads or accounts for digital GTM channels

• Integrate AI systems with pricing/catalog services, ecommerce platforms, CRM, and internal APIs.
• Partner with the business to identify high-ROI automation opportunities and measure impact on conversion, pricing accuracy, speed to quote, and revenue metrics.

Engineering, Testing & Operations

• Develop reusable libraries, patterns, and internal tooling for agent development.
• Build CI/CD pipelines, automated tests, and evaluation harnesses for LLM-powered systems.
• Monitor agent behavior in production, diagnose failures, and iterate quickly.
• Implement logging, analytics, and feedback loops to continuously improve system performance and safety.

Collaboration & Standards

• Work cross-functionally with product, engineering, and domain experts to design AI-powered workflows.
• Participate in design and code reviews, contributing to shared engineering standards.
• Help define best practices for AI evaluation, observability, and responsible deployment.

What you will bring::

Required

• 3–7+ years of experience as a Software Engineer, AI Engineer, or Machine Learning Engineer.
• Proven experience building and operating LLM-driven or agentic applications in production.
• Hands-on experience with agent frameworks or orchestration libraries (e.g., LangChain, LlamaIndex, AutoGen, Semantic Kernel, or similar).
• Strong programming skills in Python (or TypeScript/Node).
• Experience integrating LLMs with APIs, databases, vector stores, and retrieval systems.
• Solid understanding of CI/CD, containerization (Docker), and cloud deployment (AWS, GCP, or Azure).
• Experience testing, evaluating, and monitoring AI systems in real-world environments.
• Comfort working in ambiguous, fast-moving environments with end-to-end ownership.

Preferred

• Experience building pricing, quoting, ecommerce, or monetization systems.
• Familiarity with MCP servers or equivalent tool-integration architectures.
• Experience with vector databases and search/retrieval systems.
• Exposure to workflow engines, event-driven systems, or MLOps tooling.
• Background in B2B, commerce, or operationally complex industries (e.g., construction, manufacturing, distribution).
• Experience contributing to internal platforms or shared AI tooling.

What you will earn::

• Base pay range: $190,000 - $250,000
• Annual performance bonus
• Long term incentive (equity/stock)
• 401(k) with employer match
• Medical, dental, and vision insurance
• PTO, company holidays, and parental leave
• Paid Time Off/Paid Sick Leave: Applicants can expect to accrue 15 days of paid time off during their first year (4.62 hours for every 80 hours worked) and increased accruals after five years of service.
• Paid training and certifications
• Legal assistance and identity protection
• Pet insurance
• Employee assistance program (EAP)
