About the Role

Masan Group is building a centralized Data organization that serves as an internal center of excellence across our business units — spanning retail, FMCG, supply chain, and F&B. The data foundation is mature and scaling: our Databricks-based platform and enterprise data warehouse are in production, and this year we expanded the org with a dedicated Agentic AI team focused on direct business value creation.

We're looking for a Senior or Lead Data Scientist who thrives on solving real, complex business problems — not just building models. You'll own solutions end-to-end, work with high-quality data at scale, and collaborate with Data Engineering, BI, and Agentic AI teams within the same org. The DS team's mandate is clear: deliver measurable impact to the business units we serve.

Key Responsibilities

Partner with business stakeholders at WinCommerce, MCH, MML, and Phuc Long to frame and prioritize analytical problems — spanning demand planning, inventory optimization, pricing, promotion effectiveness, customer segmentation, and churn.
Own end-to-end solution delivery: data exploration, feature engineering, modeling, deployment, and production monitoring — working closely with the Data Engineering team to access and structure data on the Databricks/Data Warehouse platform.
Translate model outputs into business recommendations that stakeholders can act on — not just deliver accuracy metrics.
Contribute reusable, well-documented features to the enterprise Feature Store, enabling cross-subsidiary reuse.
Monitor model performance and business KPIs post-deployment; proactively detect drift and propose improvements.
Collaborate at a working level with the Agentic AI team on use cases where ML and agentic approaches intersect.
(Lead level) Provide technical mentorship to junior DS members; drive code and model review practices and contribute to team-wide DS standards.

Qualifications

Senior Level

4–6 years (Senior) / 6+ years (Lead) of applied data science experience in production environments — not research or pure analytics.
Proven track record solving at least 2–3 of the following problem types in FMCG, Retail, or Supply Chain contexts: demand forecasting, inventory optimization, customer segmentation, churn prediction, pricing or promotion analytics, recommendation systems, or anomaly detection.
Strong Python skills and solid ML fundamentals — knowing when to apply which approach and why, not just technical execution.
Hands-on experience with big-data platforms such as Databricks, Spark, or equivalent.
Ability to communicate findings clearly to non-technical business stakeholders — recommendations over jargon.

For Lead Level — Additional Expectations

Demonstrated scope growth beyond individual contribution: cross-team coordination, technical ownership of DS workflows, or mentoring experience.
Comfortable navigating ambiguity across multiple business stakeholders simultaneously.
Experience shaping team-level practices — feature engineering standards, model review, or tooling decisions.

Nice-to-Have

Deep domain experience in modern retail — large-scale store networks, omnichannel operations, or loyalty programs (WinCommerce-equivalent context strongly preferred).
Exposure to LLMs, embeddings, or agentic AI frameworks at a working level — sufficient for cross-team collaboration.
MLOps familiarity: MLflow, FastAPI, Docker, or CI/CD workflows for ML.

Why Join Us

Real problems at scale. You'll work on some of the most complex business challenges in Vietnamese retail and FMCG — across millions of transactions, thousands of SKUs, and a customer base that spans the country. The data is real, messy, and consequential.
A mature data foundation. No more fighting for clean data or waiting for infrastructure. Our Databricks platform and enterprise data warehouse are in production — you spend your time on the problems, not the plumbing.
A full-stack data org under one roof. Work alongside Data Engineers, BI Analysts, and a dedicated Agentic AI team. Cross-functional collaboration is the default, not the exception.
Breadth across industries. Retail, FMCG, supply chain, F&B — few data science roles in Vietnam offer this range of domains within a single organization.
Room to grow. We're hiring at Senior and Lead level because we're building, not maintaining. There is genuine scope to shape how data science is practiced at Masan Group.
Competitive compensation benchmarked to market, with a full benefits package.
