Job Description


About The Role

At Blazity, we are building modern web applications and rapidly expanding into AI-powered systems โ€” 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 โ€” 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

What You Will Do

  • Work on real AI features
  • Support development of:
    • LLM-based features
    • simple AI workflows
    • early-stage agent-like systems
  • Help with:
    • prompt design and iteration
    • testing and improving AI outputs
    • building simple integrations with LLM APIs
What We Offer

  • Hands-on experience with real AI systems in production
  • Work with experienced engineers building AI solutions
  • Fast growth path toward AI Engineer role
  • Opportunity to work on real client projects (not toy problems)
