 * Practical understanding of REST APIs, relational databases, testing, and Git.
 * Strong debugging skills and the ability to understand unfamiliar systems.
 * Attention to product behaviour, usability, and interaction details.
 * Ability to evaluate alternatives and explain your decisions clearly.
 * Initiative, good judgment, and willingness to raise problems early.
 * Good English for technical collaboration. German is a plus.

This is an early-career role, typically suited to someone with around one to two years of experience. Substantial internship, working-student, open-source, university, or independent project experience may also qualify.

Nice-to-have

 * Flutter or another mobile framework.
 * FastAPI or another backend framework.
 * PostgreSQL or Supabase.
 * Automated testing, CI/CD, Docker, or cloud deployment.
 * AI-powered, data-driven or user-facing products.

## Description

You will work across our Flutter application and FastAPI backend, taking features from problem definition through implementation and release.

We are looking for strong engineering fundamentals, evidence that you can ship working software, and the judgment to make sensible product and technical decisions. You should be effective in at least one area of the stack and capable of becoming productive across both.

This is a hands-on role with meaningful responsibility. You will be expected to investigate problems independently, form clear opinions, and take responsibility for the quality of your work.

What you'll do

 * Build end-to-end product features across our Flutter app, APIs, and database.
 * Improve interactive career-exploration, profile, and recommendation experiences.
 * Design and maintain APIs, data models, and external integrations.
 * Diagnose problems across mobile, backend, data, and infrastructure.
 * Propose and implement improvements to UX, architecture, reliability, and performance.
 * Write tests, review code, and support the release of production changes.

Requirements

Our Stack:

Mobile: Flutter and Dart
Backend: Python and FastAPI
Data: PostgreSQL and Supabase
Infrastructure: Docker and cloud services
Interfaces: REST APIs, WebSockets, and external integrations
