Founding Full-Stack Builder, Design-Led

Afitpilot; Brussel Hoofdstad; Hybride; EUR 10 000 - 17 000; Temps partiel

Résumé du poste

Afitpilot in Brussels (BeCentral) is seeking a founding Full-Stack Builder to own the end-to-end product experience. This hybrid internship places you at the heart of a two-user product and invites you to ship fast across the stack, from frontend Nuxt/Vue to backend Firebase/Firestore and Python.

You will design, build, and refine screens and flows for coaches and athletes, simplify complexity, and explore how AI suggestions can augment rather than replace user agency.

Qualifications

• Experience building full-stack applications.
• Familiarity with Nuxt/Vue frontend.
• Willingness to work across frontend and backend components.

Responsabilités

• Own end-to-end experience for both coaches and athletes.
• Design and build frontend in Nuxt/Vue; extend to backend as needed (Firebase/Firestore, Python).
• Simplify complex features to be intuitive and fast.

Connaissances

Full-stack

AI tools

Description du poste

Founding Full-Stack Builder, Design-Led

Own the whole feel of the product — and build it, across the stack.

• Brussels (BeCentral), hybrid
• Internship → early-team seat
• Pre-salary, real upside

The problem you'd own

Afitpilot has two very different users in one product. The coach needs power, control, and speed across many athletes. The athlete needs something calm and simple that just tells them what to do today. Running underneath is an AI layer that suggests but never decides, so the coach always stays in charge.

Making that legible, fast, and genuinely good to use is one of the most interesting design problems in the product, and right now it’s under-designed. You won't just draw the fix. You'll build it, across the stack.

What you'd own

• The end-to-end experience for both coaches and athletes, and the reasoning behind every screen and every button. Nothing exists "just because."
• Designing and building it. You work in our Nuxt/Vue front end, and you follow a feature into the backend (Firebase/Firestore, Python) when it needs it.
• Simplifying. A lot of what exists works but is heavier than it should be. Your job is to make it obvious.
• Figuring out how AI suggestions surface without stealing the coach's agency — a real and still unsolved UX question.

Who you are

• You already build with AI dev tools — Claude Code, Codex, Cursor, whatever your setup — and you ship fast with them. This is how we move.
• Full-stack instincts with real taste. You design well and you code, and a change in the UI usually means a change in what's behind it.
• Comfortable working the backend through prompting to start, and willing to get properly hands‑on with the full stack over time.
• You get sports. Vito and I are sports‑science people; someone who trains, coaches, or thinks about the body will design this better.
• Self‑directed and opinionated. You'll push back on my decisions, and I want that.
