Company Overview

The world needs a better food system, one that is more sustainable, more inclusive, and that brings healthier and more personalised food to all. Rohlik Group is leading this change. In every city, we carefully select the best quality and freshest local produce to save our customers time; from butchers to bakery, and fresh produce directly from farmers via our unique Farm-to-Door program. We carry all the favourite brands, plus a range of affordable own-label products, so our customers don’t miss out on what they love.

Department Overview

The AI Engineering team at Rohlik drives automation and smart decision-making across the company. We design and optimize AI-driven systems, from ETL pipelines to autonomous AI agents, and integrate them with public APIs, LLMs, and databases. Working closely with Product, Data, and Tech teams, we create scalable, data-powered solutions that improve both customer-facing products and internal operations.

Role Overview

The purpose of this role is to architect and develop both internal AI automation systems and customer-facing AI-powered systems (such as text and voice chatbots, recommendation systems, etc.) that shape the future of online retail.

The AI Engineer is responsible for designing, developing, evaluating, and maintaining core AI services and components that enable efficient decision-making across the organization and enhance the customer experience. These systems operate at a large scale, handling hundreds of concurrent requests across our e-commerce and logistics platforms. You will also act as an advocate for AI-driven transformation, bridging the gap between cutting-edge research and practical, user-centric product features.

You will join a dynamic AI Engineering team at the intersection of retail and technology. We embrace a "ship-fast" mentality, leveraging the latest advancements in LLMs and agentic workflows to solve real-world retail challenges at scale.
