Staff Applied Scientist

QXO is the fastest growing publicly traded distributor of building products in North America. The company is executing its strategy to become the tech-enabled leader in the $800 billion building products distribution industry and generate outsized value for its shareholders. QXO expects to achieve its target of $50 billion in annual revenues within the next decade through accretive acquisitions and organic growth.

Depending on your expertise, you may focus on some of the following:

o Build and productionize time series models for demand, sales, and inventory (e.g., hierarchical forecasting, intermittent demand, seasonality/trend modeling, multivariate forecasting).

o Develop approaches to handle sparse, volatile, and evolving data environments.

o Develop pricing models and policies, including elasticity estimation, margin optimization, and discounting/contract structures.

o Support pricing for quotes and BOMs, including guardrails, risk/margin checks, and complex B2B rules around bundling and substitution.

o Design models for inventory planning, replenishment, and allocation under real-world constraints (lead times, MOQs, service levels).

o Build tools to improve fill rates, reduce stockouts, and manage working capital.

o Formulate and solve optimization problems (linear, mixed-integer, non-linear, heuristics/approximation) for routing, allocation, capacity, and network flows.

o Integrate optimization with forecasting/pricing models to support end-to-end decisions.

Across all areas, you’ll:

o Combine statistical methods, machine learning, and operations research techniques as appropriate.

o Stay current on relevant research and bring practical, scalable methods into production.

o Translate messy business problems into clear technical formulations and evaluate alternative approaches.

o 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).

o Build or contribute to simulation and scenario analysis frameworks to test policies before rollout.

o Define and implement offline and online evaluation (experiments, policy evaluation, counterfactual analysis).

o Partner with data engineering to ensure data quality, structure, and accessibility for modeling.

o Define metrics for your domain (forecast accuracy, stockouts, margin impact, quote win rates, price realization, etc.).

o Design experiments and quasi-experiments to measure the business impact of new models and policies.

o Clearly communicate findings, trade-offs, and recommendations to stakeholders.

o Work closely with Sales, Marketing, Supply Chain, Finance, and Product teams to understand constraints, workflows, and incentives.

o Collaborate with AI Engineers who will embed your models inside intelligent agents and applications.

o Mentor other scientists and engineers; elevate standards around methodology, code quality, and evaluation.

o Influence roadmap and strategy by highlighting long-term modeling opportunities and risks.
