Job description

Role Summary

As a Distinguished Engineer in Data Science, you are one of the most senior technical leaders in the organization — an individual contributor whose scope, influence, and technical judgment shape how Walmart builds and operationalizes data science and ML at enterprise scale. You will define multi-year technical strategy across several data science domains, resolve the hardest ambiguous and cross-organizational technical problems, and raise the bar for engineering and scientific rigor across hundreds of engineers and data scientists. This is a hands‑on role: you are expected to prototype, review designs, write and review production‑grade code/models, and be the final technical word on the toughest calls — not just a strategist on slides.

What You’ll Do

• Set the technical vision and multi‑year roadmap for data science and applied ML across multiple product lines, ensuring alignment with enterprise data and AI strategy.


• Architect and guide the build of large‑scale ML/statistical systems (forecasting, causal inference, anomaly detection, optimization, personalization, GenAI/LLM applications) that operate reliably in production at Walmart scale.


• Act as the top technical escalation point for the hardest, most ambiguous data science problems spanning multiple teams, markets, and data domains (e.g., CA/MX international parity, cross‑market calculation standardization).


• Partner directly with VPs, Senior Directors, and Product leadership to translate business strategy into technical roadmaps, and to make build‑vs‑buy, platform, and architecture trade‑off decisions with enterprise‑wide consequences.


• Mentor and raise the technical bar for Principal and Staff Data Scientists/Engineers across the org; conduct design and code reviews that set the standard for rigor.


• Drive the adoption of modern MLOps, experimentation, and responsible‑AI practices (reproducibility, model monitoring, bias/fairness evaluation, data quality SLAs).


• Identify and de‑risk technical blockers before they become executive escalations — proactively surfacing risk, trade‑offs, and mitigation paths to leadership.


• Represent Walmart's data science capability externally and internally: publications, patents, conference talks, and internal technical guilds/communities of practice.


• Partner with Data Engineering, Platform, and Infra teams to ensure the underlying data foundation (ingestion, quality, lineage, governance) can support advanced analytics at scale.

What You’ll Bring

• 12+ years of professional experience in data science, applied machine learning, or statistics, including demonstrated enterprise‑scale production impact.


• Master's or PhD in Computer Science, Statistics, Mathematics, Operations Research, or a related quantitative field (or equivalent practical experience).


• Deep, hands‑on expertise in statistical modeling, machine learning, and/or causal inference, with a track record of shipping models/systems that materially moved business metrics at scale.


• Proven experience architecting and operating large‑scale, distributed data/ML systems (e.g., Spark, distributed training, feature stores, streaming pipelines).


• Strong software engineering fundamentals — production‑quality Python/Scala/SQL, testing, CI/CD, and cloud platforms (GCP, Azure, or AWS).


• Demonstrated ability to influence and align VP/SVP‑level stakeholders and engineering organizations without direct authority.


• A track record of mentoring senior (Staff/Principal‑level) engineers and data scientists.


• Experience in retail, supply chain, or omnichannel commerce data domains (demand forecasting, inventory, OTIF, pricing, personalization).


• Experience applying LLMs / GenAI to enterprise data products (RAG, agents, evaluation frameworks, guardrails).


• Published research, granted patents, or recognized external thought leadership in ML/AI.


• Experience operating across international markets with varying data maturity and regulatory constraints (e.g., US, Canada, Mexico).


• Prior experience as a technical founder, chief architect, or Distinguished/Fellow‑level engineer at another large‑scale technology company.
