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:\nBuild and scale our web platform used by thousands of users globally, and ensuring that it can handle the growing amount of users & orders.\nBuild 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.\nThink from a user’s perspective to design & implement slick user interfaces.\nShip features across our 3D mesh viewer; editing tools, visualization controls and model handling.\nBuild and harden integrations with scanners, printers, CAD/CAM partners, ERPs and more.\nImprove reliability and observability across the platform.\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.What you should bring to the team:\nYou 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.\nA 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).\nYou can debug: when something breaks, you dig in with logs, metrics and error-tracking tools rather than guessing.\nYou care that the code you ship works and doesn't break things around it.\nYou have an eye for design, and think from a user-perspective to build excellent UX.\nThe 'Nice-to-haves':\nExperience with 3D graphics on the web (Three.js / WebGL), meshes, or medical/scientific visualization.\nFamiliarity with cloud infrastructure and DevOps (AWS, CloudFront, CI/CD, observability tooling).\nExposure to dental, medtech or CAD/CAM domains.\nComfort building with and alongside AI/LLM tooling.\nHow you work:\nYou think sharply, and you'll be surrounded by people who do the same.\nYou'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.\nYou're reliable - people can count on you to see things through.\nYou 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.\nOur Tech Stack = Your Tech Stack:\nFrontend: Vue.js, TypeScript, Three.js\nBackend & APIs: Python, FastAPI\nData & Databases: PostgreSQL, SQLAlchemy\nInfrastructure & DevOps: AWS, Terraform, CI/CD, Docker, Kubernetes\nObservability: Sentry, Grafana, Faro RUM\nIntegrations & Partners: 3Shape, iTero, Medit Link, Formlabs, and a growing list of scanner/printer/CAD-CAM APIs\nPractical Requirements / Eligibility:\nMSc in Computer Science or something related\nExperience with front- and/or back-end related work\nFluent in English (written and spoken)\nValid work authorization in Belgium\nAble to work from our Leuven office at least 3 days per week\nWhy us?\nA mission that matters: We’re transforming dental care to make high-quality dentistry accessible globally.\nA fast-moving team that ships: A collaborative, ambitious team that executes at hyper-speed while keeping the day-to-day genuinely fun.\nA dream workspace: A sunny office with stunning views over Leuven, park walks, and coffee by the Vaartkom.\nA vibrant culture: Regular after-works, sports sessions, hackathons, and company retreats.\nUncapped growth: The opportunity to grow into broader roles as the company - and you - scale.","description_format":"text","description_chars":4070,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Belgium","iso":"BE","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Medical AI","Dental Products & Labs"],"lifecycle":[{"event":"open","at":"2026-07-28T16:29:06Z"},{"event":"open","at":"2026-09-05T16:00:00Z"}],"visa":[],"liveness":{"score":14,"band":"cold","label":"Long shot","p_open":1,"p_active":0.317,"p_room":0.44,"age_days":80,"expected_fill_days":61,"reasons":["conf:3","velocity","win:tail","crowd:"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/relu-full-stack-engineer","json_url":"https://alion.io/job/relu-full-stack-engineer.json","meta":{"generated_at":"2026-10-17T13:16:55Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":17818,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-18T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":32307},"rest":"https://alion.io/mcp/rest/get_company?id=32307"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Frelu-full-stack-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Frelu-full-stack-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Frelu-full-stack-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/relu-full-stack-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Frelu-full-stack-engineer"}]}
