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.
