## About the Role

Are you passionate about technology with a purpose? Want to make a meaningful impact on people's health? Want to work in an AI-native company? At Relu, we're growing - and we're looking for someone like you., * Product ownership and vision: You take a raw user problem, dig to the real need, and separate what's essential from what's nice to have - before you write a line of code

 * 3+ years building web product UIs, with at least 2 years owning UX decisions, not just implementing designs
 * Strong TypeScript and a modern component framework - Vue preferred, React fine if you're ready to switch
 * A portfolio or live product where you shaped the UX: you can walk us through the problem, what you tried, and why you landed where you did
 * You've built or maintained a component library or design system
 * You work well from loose specs and talk to users directly, without needing to be pushed
 * You can coach a junior engineer through code reviews and pairing sessions

The 'Nice-to-haves'

 * Experience with data-heavy B2B tools: tables, filters, dashboards, workflow builders
 * 3D or canvas work (three.js, WebGL)
 * Figma skills good enough to throw together a quick mock
 * Background in healthcare or other professional-tool environments
 * Dutch or French

How you work

 * You're an independent thinker: you don't blindly implement tickets. You think through the consequences and connections of your work and find smart solutions to problems.
 * You're reliable - people can count on you to see things through.
You communicate. You pick up a ticket, ask questions when in doubt, and then execute until it's done - without breaking other things along the way. We don't work in silos.
You think sharply, and you'll be surrounded by people who do the same.

Our Tech Stack = Your Tech Stack

 * Frontend: Vue 3, TypeScript, Vuetify, Pinia, vue-query, Nx monorepo
 * Backend & APIs: Python, FastAPI - you'll add endpoints when a feature needs it
 * Data & Databases: PostgreSQL
 * 3D: three.js (occasional, e.g. the dentist approval flow)
 * Infrastructure & DevOps: AWS, CI/CD

Practical Requirements / Eligibility

 * Fluent in English (written and spoken)
 * Valid work authorization in Belgium
 * Able to work from our Leuven office at least 3 days per week

## Description

* Design system: turn relui into a real base layer, with consistent type scale, spacing, dialogs and buttons. Build a table component that works like Linear or Notion (column config, saved views, inline edits, keyboard use).
 * Simpler order creation: a simple flow showing the main options in plain terms (for example tight, medium, loose instead of retention in mm), with the full parameter set one click away.
 * Agents simple mode: a guided mode focused on inbox status updates and a few common actions. Also a clearer view of past runs and better grouping of pieces.
 * Inbox UX: Scan Check warnings in the inbox viewer, clear sync status and errors, customizable dashboards on inbox data.
 * Dentist-facing flows: share a case with a dentist to approve or reject outputs, with drawing and comments on the 3D view.
 * Onboarding and product updates: an in-app academy, guided first steps, an in-app changelog, a notification center.
 * Ask Relu UI: make the chat less cluttered and better at guiding users through the app.

First 6 months

 * Month 1: ship two or three UX fixes across orders and inbox, and write a short UI audit of the app.
 * Months 2 to 3: design-system v1 (tokens, dialogs, buttons) and the new table component, rolled out to the inbox and orders lists.
 * Months 3 to 4: simple order-creation flow, tested with three customers.
 * Months 4 to 6: agents simple mode and the dentist approval flow., * A mission that matters: we're improving dental care and making higher-quality dentistry accessible to everyone, globally
 * A fast-growing company where your growth goes hand-in-hand with ours - real impact, real ownership, early responsibility and skills in the technologies of the future
 * The chance to work with the latest AI technologies and industry leaders in dentistry
 * Fun team culture: after-works, bi-weekly sports, hackathons, retreats
