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.
We're looking for a Product Engineer, Frontend & UX to join our Automate Platform team. Your mission is to make Automate simple for dental labs to use, and own how the product looks and feels. You will:
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.
Your profile
What you should bring to the team
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.
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
Red flags (we're honest about what doesn't fit)
You need finished designs before you can start
You talk about frameworks and never about users
Your portfolio shows implemented mockups — but no UX decisions of your own
You reach for visual flourish when the user just needed fewer steps
