AI Engineer (with backend experience in Node.js)

This role is about bringing AI features into real products. You’ll work with LLMs, APIs, and backend logic — connecting intelligent systems to working apps.

We’re looking for an engineer who’s comfortable switching between AI experiments and backend implementation — someone curious, fast-learning, and product-oriented.

Required skills:

• 6+ months of hands-on AI / ML experience (LLMs, model APIs, prompt engineering, fine-tuning, etc.)
• Solid backend development experience with Node.js
• Experience integrating AI APIs (OpenAI, Claude, Gemini, etc.)
• Understanding of REST APIs and backend architecture
• Experience with Git and version control
• Strong debugging and testing habits
• Good communication and teamwork skills

Nice to have:

• Experience with Docker
• Familiarity with LangChain, Haystack, or RAG pipelines
• Experience in data preprocessing / ETL
• Interest in data analysis and AI-driven product features

Responsibilities:

• Build and maintain AI-driven features and services
• Integrate LLMs and AI APIs into backend systems
• Collaborate with backend and data teams
• Experiment with model fine-tuning and prompt optimization
• Maintain code quality and documentation

We offer:

• Innovative team and friendly environment
• Flexible hours and remote-first mindset
• Work with cutting-edge AI tools in real product scenarios
