What We're Looking For

Bachelor's or Master's in IT, or equivalent experience — with at least 5 years in software development Strong engineering fundamentals: clean code, testing, version control Hands-on experience with Java/Spring, testing frameworks (JUnit, Playwright), and SQL databases An AI-native mindset: you use tools like Claude Code, Cursor, or Copilot daily, and know when AI helps and when it doesn't Strong analytical and communication skills — you think along, speak up, and challenge when needed Experience with frontend technologies Experience with cloud platforms (AWS) ATTENTION UPON DROPPING YOUR APPLICATION: Please, immediately send an email with subject 'AI Native Full Stack Engineer – Your Name' sharing concrete examples of Java/Spring backend work you've done in production. We're specifically interested in: Java/Spring services you've designed or maintained in production — the scale, key architecture decisions, and how you approached testing (JUnit, Playwright) SQL database work you've owned — schema design, query optimisation, or migrations Legacy code you refactored or technical debt you paid down — what was wrong, what you changed, and the outcome How you use AI coding tools (Claude Code, Cursor, Copilot) day-to-day — a specific example where AI sped things up, and one where you deliberately didn't use it Frontend or AWS/cloud experience, if you have it — what you built and your role in it Please point us to production work, not tutorials, side experiments, or course projects. A short paragraph per example is enough. Vague answers like "I use Copilot for most of my coding now" won't move you to the next stage, specifics will.
