Junior AI Engineer (Next.js & LLM)

Junior • Remote

Warsaw, Poland

About the Role

At Blazity, we are building modern web applications and rapidly expanding into AI-powered systems — agents, automation, and LLM-based workflows.

We are looking for a high-potential Junior AI Developer (student or early career) who is strongly interested in AI and LLMs, actively experiments with them, and wants to turn that into real-world, production experience.

This is not a standard frontend role — this is an AI-first position, where web development is a tool to build intelligent systems.

Our requirements

AI-first mindset

You actively use agentic coding tools like: Claude Code / Codex / Cursor
You have experimented with AI, e.g.:
- building a chatbot
- automating tasks with LLMs
- generating structured outputs
You are curious:
- how LLMs work
- how to build real AI features (not just use them)
This role is for people who already do things with AI, not just read about it.

Technical foundations

Knowledge of:
- JavaScript / TypeScript
- React or Next.js (even small projects)
Understanding of APIs (REST basics)

Learning mindset

You learn by building (projects > theory)
You are comfortable making mistakes and iterating
You are proactive and self-driven

Big plus

First experience with:
- OpenAI / Anthropic APIs
- prompt engineering (structured output, few-shot)
You built:
- small AI apps (chatbot, automation, AI tool)
GitHub projects showing AI experiments
Participation in hackathons (especially AI-related)

Other

English C1

Support development of:
- LLM-based features
