Applied Scientist

We’re looking for bold, entrepreneurial talent ready to help build something extraordinary — and reshape the future of building products distribution.

QXO is a publicly traded company founded by Brad Jacobs with the goal of building the market-leading company in the building products distribution industry. On April 30, 2025, QXO completed its first acquisition:
Beacon Building Products, a leading distributor in the sector.

We are building a customer-focused, tech-enabled, and innovation-driven business that will scale rapidly through accretive M&A, organic growth, and greenfield expansion. Our strategy is rooted in delivering exceptional customer experiences, improving operational efficiency, and leveraging data, digital tools, and AI to modernize a historically under-digitized industry.

• Forecasting
  • Build and product ionize time series models for demand, sales, and inventory (e.g., hierarchical forecasting, intermittent demand, seasonality/trend modeling, multivariate forecasting).
  • Develop approaches to handle sparse, volatile, and evolving data environments.
• Pricing & Revenue
  • Develop pricing models and policies, including elasticity estimation, margin optimization, and discounting/contract structures.
  • Support pricing for quotes and BOMs, including guardrails, risk/margin checks, and complex B2B rules around bundling and substitution.
• Supply Chain & Inventory
  • Design models for inventory planning, replenishment, and allocation under real-world constraints (lead times, MOQs, service levels).
  • Build tools to improve fill rates, reduce stockouts, and manage working capital.
  • Formulate and solve optimization problems (linear, mixed‑integer, non‑linear, heuristics/approximation) for routing, allocation, capacity, and network flows.
  • Integrate optimization with forecasting/pricing models to support end‑to‑end decisions.
• Across all areas
  • Combine statistical methods, machine learning, and operations research techniques as appropriate.
  • Stay current on relevant research and bring practical, scalable methods into production.

• Translate messy business problems into clear technical formulations and evaluate alternative approaches.
• Work with engineers to turn models into robust services powering internal tools, APIs, and AI agents (e.g., quoting & BOM agents, pricing copilots, supply planning tools).
• Build or contribute to simulation and scenario analysis frameworks to test policies before rollout.
• Define and implement offline and online evaluation (experiments, policy evaluation, counterfactual analysis).

• Partner with data engineering to ensure data quality, structure, and accessibility for modeling.
• Define metrics for your domain (forecast accuracy, stockouts, margin impact, quote win rates, price realization, etc.).
• Design experiments and quasi-experiments to measure the business impact of new models and policies.
• Clearly communicate findings, trade‑offs, and recommendations to stakeholders.

• Work closely with Sales, Marketing, Supply Chain, Finance, and Product teams to understand constraints, workflows, and incentives.
• Collaborate with AI Engineers who will embed your models inside intelligent agents and applications.
• Mentor other scientists and engineers; elevate standards around methodology, code quality, and evaluation.
• Influence roadmap and strategy by highlighting long‑term modeling opportunities and risks.

• 7+ years of experience in Applied Science / Data Science / Quantitative Research, with a strong record of shipping models into production.
• Deep expertise in one or more of the following:
  • Time series forecasting
  • Pricing & revenue management
  • Supply chain / inventory / logistics modeling
  • Operations research / mathematical optimization
• Strong proficiency in Python and scientific computing libraries (Num Py, pandas, etc.).
• Solid SQL skills and experience working with modern data warehouses/lake houses.
• Hands‑on experience designing experiments, analyzing results, and working with ambiguous real‑world data.
• Excellent communication skills and demonstrated ability to lead projects…
