Applied AI Engineer

We are looking for a Full Stack AI Engineer to join our AI product team at Rast Mobile. You will help us improve and develop our main AI product, ThinkHub, which uses local large language models (LLMs) like DeepSeek, Mistral, and LLaMA.

This role is focused on real-world AI applications, not just research or small demos. You’ll work on everything from getting AI models to run locally to building backend services that connect AI to business problems.

What You’ll Do

• Work with local or private AI models (DeepSeek, Mistral, etc.)
• Build tools using RAG (Retrieval-Augmented Generation) and agent systems
• Create and test prompts, connect models to real data
• Use frameworks like LangChain or LlamaIndex
• Store and search data using vector databases like pgvector or Weaviate
• Build and maintain backend services with Python or Node.js
• Make sure everything runs fast, safe, and stable

What We Expect

• You’ve worked with local LLMs before (or want to learn deeply)
• You’re good at backend development (Python or Node.js)
• You understand how to manage data, search it, and give it to models
• You can build and test real AI systems, not just toy projects
• You care about clean, working code and solving real problems
