We are looking for a Senior Data Scientist to support modeling and analytics for retail measurement data within the Korean FMCG market.

In this role, you will work as part of a collaborative team to solve client-driven business challenges. Rather than working independently, you will be assigned to projects by a team manager, partnering with cross-functional team members to define methodologies, align on analytical approaches, and shape client communication strategies.

A key responsibility of this role is to develop and validate Universe (population) definitions and projection methodologies, ensuring that panel data is accurately expanded to reflect the overall market.

Beyond analysis, you will play a critical role in translating data outputs into clear, compelling business narratives, explaining assumptions, methodologies, and reasoning directly to clients.

• Develop and maintain data models for FMCG / retail measurement in the Korean market
• Design, validate, and refine Universe setting and projection methodologies based on panel data
• Perform data cleaning, processing, and quality validation to ensure robust output
• Collaborate with internal teams to define analytical approaches and methodologies for client projects
• Translate analytical findings into clear, structured storytelling for client communication
• Present reasoning behind methodologies, assumptions, and outputs to clients
• Continuously improve data quality, projection accuracy, and modeling approaches
• Manage stakeholder expectations and contribute to effective project delivery

• Bachelor’s degree or above in Statistics, Mathematics, Economics, Data Science, or a related field
• Around 6+ years of experience in FMCG, retail measurement, consumer analytics, or related industries
• Hands-on experience with Python for data analysis and modeling (required)
• Solid understanding of data processing, statistical concepts, and modeling fundamentals
• Experience working with SQL and large-scale datasets
• Strong English communication skills (both written and spoken) — ability to effectively communicate with global teams and explain analytical outputs to clients

Preferred Qualifications

• Experience with consumer panel data, retail measurement, or similar datasets
• Hands-on experience with Universe building and projection methodologies
• Prior experience working in a project-based, team-driven environment
• Exposure to stakeholder and client-facing roles

Our Benefits

• Flexible working environment
• Volunteer time off
• LinkedIn Learning
• Employee-Assistance-Program (EAP)
