We are seeking an AI Engineer to join our AI & Automation team. In this role, you'll design and build AI-based tools and systems for the retail business. You will take problems from the first stakeholder conversation through rapid prototyping cycles to a working solution that real users depend on, choosing the technique that fits each problem - LLMs and RAG, agents, computer vision, or classic machine learning.

This role involves owning solutions from idea to production: designing a solution with business analysts and stakeholders, building a POC quickly to prove value, then hardening it into a production-grade service. This is a hands-on engineering role - most of your week is spent building. You should be comfortable collaborating with both business and technical stakeholders, explaining technical choices to non-technical users, and contributing to the organization's broader digital transformation.

Responsibilities:

• Build and Innovate AI solutions for real business problems, from first prototype to production

• Collaborate with business analysts to turn stakeholder needs into a working demo, then iterate on it with real users

• Apply a range of AI techniques - LLMs and RAG, agents, computer vision, classic machine learning and choose the one that fits the problem

• Deploy and maintain solutions on Azure, and improve existing ones as processes evolve

• Contribute to the team's continuous learning.

We offer:

• Professional development, training, and career opportunities within the Kesko Senukai Group

• Additional health insurance after 6 months of employment

• Bonuses ranging from €600 to €1,700 for referring friends who are successfully hired

• SMART NET Gold loyalty program membership, with access to exclusive offers and discounts

• A partner discount platform with even more exclusive offers

• Additional benefits for important life events, such as the birth of a child, marriage, or bereavement

• An additional day off for your birthday

• Comprehensive onboarding, as well as a supportive and proactive team

• Team-building activities and company events.

Requirements:

• 2+ years of hands-on software development experience •

• Experience with AI-assisted development (e.g. Claude Code, Cursor)

• An ownership mindset - you hold the solutions you build to a high standard of quality, testing what you ship and fixing what breaks

• Solid programming skills in at least one modern language (JavaScript/TypeScript, Python or similar)

• Practical understanding of how LLMs behave in production - prompting, structured outputs, RAG and vector search, evaluation, failure modes

• Experience with REST APIs, Git and Docker

• Excellent communication in Lithuanian and English

• Confidence working directly with business stakeholders and translating their needs into technical solutions.

Nice to have:

• Practical experience building Generative-AI-based solutions or Machine Learning technologies

• Experience building agentic setups - Agentic tools, plugins, MCP servers

• Experience with Azure or another cloud platform, and with CI/CD pipelines

• Experience with LLM frameworks and tooling such as LangChain, LlamaIndex or Azure AI services

• Experience with computer vision or classic ML models

Salary:

€3,500–€4,500 gross (before taxes). The final salary will be agreed individually, based on the candidate’s experience.
