Junior Full-Stack Developer (TypeScript / React ・ Supabase / Postgres)

Location:  Hungary  Type:  Full-time or working student / part-time - both welcome  Level:  Junior ・ Working student ・ Recent graduate Why this role We build software that real businesses run on. You'll join a small, senior team where you own real features early ― not tickets that someone pre-chewed for you. You'll learn fast, ship to production within your first weeks, and have a senior engineer in your corner the whole way. This is a role for someone early in their career who thinks in  systems , not just syntax. Let's be honest about AI (please read this) We don't expect you to hand-type every line from memory, and we don't want you to. Of course you'll use Cursor, Copilot, Claude, and whatever comes next ― that's not cheating, that's the job in 2026. We  want  you to vibe-code. But here's the thing the tools  can't  do for you: they don't know what the right answer is.  We hire for that.  Our focus is architecture and judgment  ― the ability to decide what should be built, how the data should be shaped, where a responsibility belongs, and whether the code the AI just generated is actually correct, secure, and maintainable, or just plausible-looking. So the bar isn't "can you write a for-loop without help." The bar is:  do you understand the system well enough to steer the tools and recognize a good result when you see one?  If you're early in your career but you genuinely _get_how the pieces fit together, you're exactly who we're looking for. Tasks What you'll do Build product features end to end with AI-assisted tooling: database → API → React UI. Learn to model data properly in  Postgres  ― schema, relationships, migrations, and Supabase Row-Level Security ― and understand  why it's structured that way. Build clean, usable interfaces in  React + TypeScript . Read, question, and improve the code you and the tools produce ― and learn to tell solid architecture from a shortcut that'll hurt later. Grow quickly with real mentorship, code reviews, and ownership. Our stack (what you'll learn on the job) Languages:  TypeScript, Python Frontend:  React, [Next.js / Vite], Tailwind CSS Backend / Data: Supabase (Postgres, Auth, Storage, Edge Functions), SQL, RLS Tooling:  Git/GitHub, CI/CD, Claudflare, and the AI dev tools you already use AI-native workflow:  Cursor / Copilot / Claude as a normal part of how we build Sysops : Debian, terminal, etc You won't know all of this on day one. No junior does. You'll learn it here. Requirements What we're looking for Must-haves A real foundation in  TypeScript / JavaScript and React  ― through study, side projects, an internship, or things you've built for fun. Architectural curiosity:  you care  why  code is structured a certain way, not just whether it runs. Basic comfort with  SQL / relational data  ― or the clear ability to pick it up fast. You use AI dev tools well and critically ― you don't blindly paste whatever they output. You communicate clearly in  English  and you're genuinely eager to learn. Based in Hungary, or able to work reliably within CET hours. Nice-to-haves A GitHub or portfolio with something you actually built - however small or messy. Exposure to Supabase, Firebase, or any Postgres-backed app. An eye for UI/UX. Currently studying computer science or similar (working-student arrangement very welcome). German or another European language (not required ― English is our working language). We care far more about how you think than about your CV length. Benefits How we work Small team  ― you learn directly from people who've shipped a lot, and your work matters from week one. Hybrid:  a real office in HU plus flexibility to work from home most of the week. Student-friendly:  flexible hours; we'll work around your lectures and exams. Low bureaucracy:  clear ownership, short feedback loops, no death-by-process. What we offer Fair junior compensation with clear room to grow. Real mentorship ― not "figure it out alone." Modern hardware and the AI tooling you need. A learning budget for courses, books, and conferences. The chance to grow into a serious engineer on a product that real customers use. How to apply Send a short note about yourself plus your  GitHub / portfolio / LinkedIn. Built something you're proud of ― or even something broken you learned from? Link it. A CV is welcome, but what you've made and how you think tells us more. No essay required. We review every application and reply to everyone.
