Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Full-Stack Engineer - **Company:** Relu - **Location:** Leuven, Belgium - **Contract:** Internship / Graduate position - **Skills:** 3D Printing, 3D Computer Graphics Software, Application Programming Interfaces (APIs), Artificial Intelligence, Amazon Web Services, Amazon Cloudfront, Cloud Computing, Databases, Continuous Integration, Software Debugging, DevOps, Python (Programming Language), PostgreSQL, SQLAlchemy, Systems Integration, TypeScript, Web Applications, Web Platforms, WebGL, Three.js, Datadog, ReactJS, Large Language Models, Grafana, Backend, Fastapi, Vue.js, Kubernetes, Information Technology, Sentry, Front End Software Development, Terraform, Docker - **Published:** August 2, 2026 - **Apply:** https://www.adzuna.be/details/5824081390 ## 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., * 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 ## Description 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. 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. ## Related Videos - [Rendering Design Software in the Browser at Penpot](https://www.wearedevelopers.com/videos/1353-rendering-design-software-in-the-browser-at-penpot) - [From DevOps to Scaled DevOps: How We’re Rebuilding Continuous Delivery as a Platform](https://www.wearedevelopers.com/videos/100018-from-devops-to-scaled-devops-how-we-re-rebuilding-continuous-delivery-as-a-platform) - [Lessons learned from building a thriving Vue.js SaaS application](https://www.wearedevelopers.com/videos/1666-lessons-learned-from-building-a-thriving-vue-js-saas-application) - [Recruitment Reinvented: Bold strategies and the $10K signing incentive](https://www.wearedevelopers.com/videos/1068-recruitment-reinvented-bold-strategies-and-the-10k-signing-incentive) - [TresJS a new declarative ThreeJS as Vue components](https://www.wearedevelopers.com/videos/543-tresjs-a-new-declarative-threejs-as-vue-components) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [Find a Developer Job: 12 Best Job Sites For Developers](https://www.wearedevelopers.com/magazine/165-find-a-developer-job-12-best-job-sites-for-developers) - [The Biggest German Tech Companies](https://www.wearedevelopers.com/magazine/424-the-biggest-german-tech-companies) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Where To Find Software Engineering Jobs](https://www.wearedevelopers.com/magazine/396-where-to-find-software-engineering-jobs)
