Intern/Working Student – Frontend Development (m/f/x)

Intern / Student, Full or part-time · Munich, Frankfurt

Join Our Mission

At Quantagonia, our founders have built and scaled successful companies, including achieving Unicorn status. But throughout their journey, they saw a recurring problem: while optimization has the potential to solve huge planning challenges, it has always been too complex and out of reach for most businesses.

That’s why we created DecisionAI—to make real-time, AI-powered optimization accessible for everyone. We’re tackling the biggest challenges of our time, from cutting kilometers and costs in logistics to solving complex distribution puzzles, mastering scheduling challenges, and enabling fascinating production optimizations.

This is your chance to bring your theoretical knowledge into real-world action and see the results of your work on the greatest playground of all: the real world. ????
‍
Join us to build interactive, data-driven web applications that bring our DecisionAI engine to life. You won't be working on landing pages or marketing websites—instead, you’ll help create dynamic internal tools, business UIs, and decision support interfaces.

Tasks

Help Ship the very first user-facing screens of DecisionAI. Build real apps, not static sites: Develop user-facing features in React/TypeScript, transforming complex logic and real-time data into intuitive UIs.
Partner closely with backend & design. Consume our Django Ninja REST API, keep state in sync, and turn Figma mock-ups into fully responsive UIs. Your feedback will shape both UX and APIs.
Own features end-to-end. Scope a slice of the product with product/design, build it, ship it, and track the metrics that define “done.”
Level-up developer experience. CI linting, or visual-regression tests so the whole team ships faster.

Requirements

Enrolled in a Bachelor’s or Master’s program in Computer Science, Media Informatics, or similar — or equivalent self-taught experience.
Solid grasp of JavaScript/TypeScript and React (hooks, context, functional components) —especially building stateful, multi-screen applications.
Comfortable with semantic HTML5 and modern CSS; familiarity with utility-CSS frameworks like Tailwind is a plus.
Basic understanding of REST APIs, client-side routing, and application architecture (e.g., CSR/SSR); some exposure to Django or another Python web framework.
You know Git workflows and have written basic frontend tests.
Fluent in English (spoken & written); German is a plus.
Startup mindset: you show initiative, take ownership, and thrive on shipping and iterating quickly.
Nice to Have:
- Hands-on work with REST / OpenAPI backends, especially Django Ninja or FastAPI.
- Interest in design systems, accessibility, or performance budgeting.
- Personal or academic projects you can share (GitHub, portfolio, etc.).

Benefits

Real Impact: Work directly with founders and see your contributions drive tangible results.
Learn and Grow: Gain first-hand insights into building and scaling a business.
Career Boost: Develop skills and experiences that open doors to future opportunities.
On-Site Perks: All-inclusive office setup in Frankfurt or Munich with some flexibility for remote work.
Stay Healthy: Access to health and sports memberships.‍
Team Spirit: Enjoy regular team events and offsites.
