Senior Full Stack Developer

Senior • On-site

20,000 - 30,000 PLN/yr

Bialystok, PD, Poland

Vibe coding is real.

We are looking for a builder with a real technical foundation who knows how to move fast with AI without losing touch with how systems actually work.

This role is for someone with a real grounding in web development, systems, architecture, APIs, databases, and modern engineering practices — but who also understands that AI has fundamentally changed how great products get built.

You should already be comfortable with

  • Claude, ChatGPT, Codex, and modern AI coding workflows
  • Cursor, Windsurf, OpenClaw/OpenCode-style tools, and agentic development environments
  • Prompting, context management, structured outputs, and tool use
  • Local model experimentation with LM Studio, vLLM, or similar tools
  • Fine-tuning, LoRA/QLoRA, Unsloth, or a willingness to learn these quickly
  • Automation, scripting, APIs, and AI-assisted debugging
  • Knowing when AI is useful, when it is wrong, and when human engineering judgment matters

Benefits

  • Access to the latest models
  • Generous token usage
  • Freedom to experiment
  • Real ownership
  • Minimal bureaucracy
  • A fast-moving environment focused on execution

What we care about

  • Getting things done
  • Strong technical intuition
  • Curiosity and initiative
  • Understanding how systems actually work
  • Knowing when AI is correct and when it is hallucinating nonsense
  • Speed, adaptability, and ownership
  • Someone who constantly questions “why?”

We are not looking for people emotionally attached to old ways of working.

We are looking for people who can leverage AI properly because they already understand technology at a foundational level. The vibes only work when they come from competence.

This role is for builders who can take ideas from concept to production rapidly, responsibly, and confidently.
