Strong Junior Applied AI Engineer (LLM/RAG)

Summary

Build and improve production AI systems using LLMs and RAG pipelines, integrating them with backend services and evaluating performance.

We are looking for an Applied AI Engineer to help our team design, develop, and improve production AI systems powered by LLMs.

Develop and improve LLM and RAG pipelines.
Work with structured outputs, tool calling, and agentic workflows.
Integrate AI components with backend systems and external services.
Evaluate model performance and reduce errors.
Research and apply new AI approaches.
Use Claude Code, Codex, and other AI development tools.

Requirements
1+ year of commercial software development experience.
Strong knowledge of at least one programming language: Python, JavaScript/TypeScript, Java/Kotlin, C#, or another backend language.
Practical experience with LLM APIs or AI-powered features.
Understanding of RAG, embeddings, vector search, and prompt engineering.
Experience with APIs, databases, and Git.
Strong technical thinking, independence, and a desire to grow in Applied AI.
