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.\n\nWe'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:\n• Build and scale our web platform used by thousands of users globally, and ensuring that it can handle the growing amount of users & orders.\n• 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.\n• Think from a user’s perspective to design & implement slick user interfaces.\n• Ship features across our 3D mesh viewer; editing tools, visualization controls and model handling.\n• Build and harden integrations with scanners, printers, CAD/CAM partners, ERPs and more.\n• Improve reliability and observability across the platform.\n\nYour profile\nWe'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.\n\nWhat you should bring to the team:\n• You can find your way around both a frontend (TypeScript/Vue) and a backend (Python/FastAPI) codebase. You don't have to be expert in both, but you're not afraid of either.\n• 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).\n• You can debug: when something breaks, you dig in with logs, metrics and error-tracking tools rather than guessing.\n• You care that the code you ship works and doesn't break things around it.\n• You have an eye for design, and think from a user-perspective to build excellent UX.\n\nThe 'Nice-to-haves':\n• Experience with 3D graphics on the web (Three.js / WebGL), meshes, or medical/scientific visualization.\n• Familiarity with cloud infrastructure and DevOps (AWS, CloudFront, CI/CD, observability tooling).\n• Exposure to dental, medtech or CAD/CAM domains.\n• Comfort building with and alongside AI/LLM tooling.\n\nHow you work:\n• You think sharply, and you'll be surrounded by people who do the same.\n• 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.\n• You're reliable — people can count on you to see things through.\n• 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.\n\nOur Tech Stack = Your Tech Stack:\n• Frontend: Vue.js, TypeScript, Three.js\n• Backend & APIs: Python, FastAPI\n• Data & Databases: PostgreSQL, SQLAlchemy\n• Infrastructure & DevOps: AWS, Terraform, CI/CD, Docker, Kubernetes\n• Observability: Sentry, Grafana, Faro RUM\n• Integrations & Partners: 3Shape, iTero, Medit Link, Formlabs, and a growing list of scanner/printer/CAD-CAM APIs\n\nPractical Requirements / Eligibility:\n• MSc in Computer Science or something related\n• Experience with front- and/or back-end related work\n• Fluent in English (written and spoken)\n• Valid work authorization in Belgium\n• Able to work from our Leuven office at least 3 days per week\n\nWhy us?\n• A mission that matters: We’re transforming dental care to make high-quality dentistry accessible globally.\n• A fast-moving team that ships: A collaborative, ambitious team that executes at hyper-speed while keeping the day-to-day genuinely fun.\n• A dream workspace: A sunny office with stunning views over Leuven, park walks, and coffee by the Vaartkom.\n• A vibrant culture: Regular after-works, sports sessions, hackathons, and company retreats.\n• Uncapped growth: The opportunity to grow into broader roles as the company — and you — scale.","responsibilities_text":"Are you passionate about technology with a purpose?
