Data Scientist

DemandTec is a retail analytics and demand science platform used by grocery retailers and CPG suppliers to run pricing, promotions, markdowns, and trade fund decisions on connected, AI-powered intelligence rather than siloed point solutions. Backed by Longshore Capital, we're modernizing a market-leading core into an AI/ML-native, composable platform — with a live network of 7,800+ connected CPG suppliers, the largest and hardest-to-replicate asset in the category.

We're building the next generation of our solution platform for retail and analytics: GenAI-powered agents, real-time decisioning, and connected optimization across pricing, promotions, markdowns, and trade funds. This team sits at the center of that build.

We're hiring a Data Scientist in Poland to help build the ML and GenAI capabilities behind our next-generation retail and analytics platform. You'll work closely with the Lead Data Scientist and a distributed team to build models, ship GenAI features, and turn retail/CPG data into decisions that matter to our customers.
