Key responsibilities

  • Build and scale the web platform used by thousands of users globally, ensuring it can handle increasing users and orders.

  • Develop agents that automate processes such as patient scan intake, order entry, customer emails, and 3D print queues.

  • Design and implement user interfaces and ship features for the 3D mesh viewer, editing tools, visualization controls, and model handling.

Job description

Your mission

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 Full-Stack Engineer to join our Platform team; the web app, 3D viewer, workflow automations, integrations and infrastructure that hundreds of dental professionals rely on every day. You will:

  • Build and scale our web platform used by thousands of users globally, and ensuring that it can handle the growing amount of users & orders.
  • Build agents that run the digital backbone of a dental lab; automating everything from patient scan intake and order entry to customer emails and 3D print queues.
  • Think from a user’s perspective to design & implement slick user interfaces.
  • Ship features across our 3D mesh viewer; editing tools, visualization controls and model handling.
  • Build and harden integrations with scanners, printers, CAD/CAM partners, ERPs and more.
  • Improve reliability and observability across the platform.
Your profile

We're open on experience level. What matters is that you have some real hands-on experience: an internship, your own projects, or applied work with others. Whether you're fresh out of your Master's or have a few years of front-end work behind you, if you're smart and ready to contribute, we want to hear from you.

What you should bring to the team:
  • You can find your way around both a frontend (TypeScript/React) and a backend (Python/FastAPI) codebase. You don't have to be expert in both, but you're not afraid of either.
  • A working understanding of databases and APIs, and the curiosity to reason about *why* something behaves the way it does (transactions, race conditions, third-party integrations with auth and rate limits).
  • You can debug: when something breaks, you dig in with logs, metrics and error-tracking tools rather than guessing.
  • You care that the code you ship works and doesn't break things around it.
  • You have an eye for design, and think from a user-perspective to build excellent UX.
The 'Nice-to-haves':
  • Experience with 3D graphics on the web (Three.js / WebGL), meshes, or medical/scientific visualization.
  • Familiarity with cloud infrastructure and DevOps (AWS, CloudFront, CI/CD, observability tooling).
  • Exposure to dental, medtech or CAD/CAM domains.
  • Comfort building with and alongside AI/LLM tooling.
How you work:
  • You think sharply, and you'll be surrounded by people who do the same.
  • 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.
Our Tech Stack = Your Tech Stack:
  • Frontend: Vue.js, TypeScript, Three.js
  • Backend & APIs: Python, FastAPI
  • Data & Databases: PostgreSQL, SQLAlchemy
  • Infrastructure & DevOps: AWS, Terraform, CI/CD, Docker, Kubernetes
  • Observability: Sentry, Grafana, Faro RUM
  • Integrations & Partners: 3Shape, iTero, Medit Link, Formlabs, and a growing list of scanner/printer/CAD-CAM APIs
Practical Requirements / Eligibility:
  • MSc in Computer Science or something related
  • Experience with front- and/or back-end related work
  • Fluent in English (written and spoken)
  • Valid work authorization in Belgium
  • Able to work from our Leuven office at least 3 days per week
Why us?
  • A mission that matters: We’re transforming dental care to make high-quality dentistry accessible globally.
  • A fast-moving team that ships: A collaborative, ambitious team that executes at hyper-speed while keeping the day-to-day genuinely fun.
  • A dream workspace: A sunny office with stunning views over Leuven, park walks, and coffee by the Vaartkom.
  • A vibrant culture: Regular after-works, sports sessions, hackathons, and company retreats.
  • Uncapped growth: The opportunity to grow into broader roles as the company — and you — scale.
