You will: <ul><li>Build and scale our web platform used by thousands of users globally, and ensuring that it can handle the growing amount of users & orders.</li><li>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.</li><li>Think from a user’s perspective to design & implement slick user interfaces.</li><li>Ship features across our 3D mesh viewer; editing tools, visualization controls and model handling.</li><li>Build and harden integrations with scanners, printers, CAD/CAM partners, ERPs and more.</li><li>Improve reliability and observability across the platform.</li></ul> Your profile We're open on experience level.

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:<ul><li style="font-family:Verdana, Geneva, sans-serif;">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.</li><li style="font-family:Verdana, Geneva, sans-serif;">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).</li><li style="font-family:Verdana, Geneva, sans-serif;">You can debug: when something breaks, you dig in with logs, metrics and error-tracking tools rather than guessing.</li><li style="font-family:Verdana, Geneva, sans-serif;">You care that the code you ship works and doesn't break things around it.</li><li style="font-family:Verdana, Geneva, sans-serif;">You have an eye for design, and think from a user-perspective to build excellent UX.</li></ul> The 'Nice-to-haves':<ul><li style="font-family:Verdana, Geneva, sans-serif;">Experience with 3D graphics on the web (Three.js / WebGL), meshes, or medical/scientific visualization.</li><li style="font-family:Verdana, Geneva, sans-serif;">Familiarity with cloud infrastructure and DevOps (AWS, CloudFront, CI/CD, observability tooling).</li><li style="font-family:Verdana, Geneva, sans-serif;">Exposure to dental, medtech or CAD/CAM domains.</li><li style="font-family:Verdana, Geneva, sans-serif;">Comfort building with and alongside AI/LLM tooling.</li></ul> How you work:<ul><li style="font-family:Verdana, Geneva, sans-serif;">You think sharply, and you'll be surrounded by people who do the same.</li><li style="font-family:Verdana, Geneva, sans-serif;">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.</li><li style="font-family:Verdana, Geneva, sans-serif;">You're reliable — people can count on you to see things through.</li><li style="font-family:Verdana, Geneva, sans-serif;">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.</li></ul> Our Tech Stack = Your Tech Stack: <ul><li style="font-family:Verdana, Geneva, sans-serif;">Frontend: Vue.js, TypeScript, Three.js</li><li style="font-family:Verdana, Geneva, sans-serif;">Backend & APIs: Python, FastAPI</li><li style="font-family:Verdana, Geneva, sans-serif;">Data & Databases: PostgreSQL, SQLAlchemy</li><li style="font-family:Verdana, Geneva, sans-serif;">Infrastructure & DevOps: AWS, Terraform, CI/CD, Docker, Kubernetes</li><li style="font-family:Verdana, Geneva, sans-serif;">Observability: Sentry, Grafana, Faro RUM</li><li style="font-family:Verdana, Geneva, sans-serif;">Integrations & Partners: 3Shape, iTero, Medit Link, Formlabs, and a growing list of scanner/printer/CAD-CAM APIs</li></ul> Practical Requirements / Eligibility: <ul><li style="font-family:Verdana, Geneva, sans-serif;">MSc in Computer Science or something related</li><li style="font-family:Verdana, Geneva, sans-serif;">Experience with front- and/or back-end related work</li><li style="font-family:Verdana, Geneva, sans-serif;">Fluent in English (written and spoken)</li><li style="font-family:Verdana, Geneva, sans-serif;">Valid work authorization in Belgium</li><li style="font-family:Verdana, Geneva, sans-serif;">Able to work from our Leuven office at least 3 days per week</li></ul> Why us? <ul><li style="border:0px solid;margin:0px;font-family:Verdana, Geneva, sans-serif;">A mission that matters: We’re transforming dental care to make high-quality dentistry accessible globally.</li><li style="border:0px solid;margin:0px;font-family:Verdana, Geneva, sans-serif;">A fast-moving team that ships: A collaborative, ambitious team that executes at hyper-speed while keeping the day-to-day genuinely fun.</li><li style="border:0px solid;margin:0px;font-family:Verdana, Geneva, sans-serif;">A dream workspace: A sunny office with stunning views over Leuven, park walks, and coffee by the Vaartkom.</li><li style="border:0px solid;margin:0px;font-family:Verdana, Geneva, sans-serif;">A vibrant culture: Regular after-works, sports sessions, hackathons, and company retreats.</li><li style="border:0px solid;margin:0px;font-family:Verdana, Geneva, sans-serif;">Uncapped growth: The opportunity to grow into broader roles as the company — and you — scale.</li></ul>
