Internship Fastapi information

What is an internship in FastAPI?

An Internship in FastAPI is a temporary position for students or recent graduates to gain hands-on experience working with FastAPI, a modern Python web framework for building APIs. Interns typically assist in developing, testing, and deploying web applications using FastAPI, often under the guidance of experienced developers. This internship helps participants strengthen their Python programming skills, learn best practices in API development, and understand the workflow of real-world software projects. It also offers networking opportunities and can serve as a stepping stone to a full-time role in backend or web development.

What types of projects can interns expect to work on during a FastAPI internship?

As a FastAPI intern, you will typically work on building and enhancing backend APIs, often as part of a development team focused on creating scalable web services or integrating third-party APIs. Projects may include implementing new endpoints, optimizing performance, writing automated tests, and collaborating with frontend developers to ensure seamless data flow. You'll gain experience with asynchronous programming, modern Python practices, and tools like Docker and Git, while often participating in code reviews and agile sprint meetings. This hands-on exposure is valuable for understanding real-world backend development workflows and best practices.

What are the key skills and qualifications needed to thrive as an internship FastAPI developer, and why are they important?

To thrive as an Internship FastAPI developer, you need a solid understanding of Python programming, RESTful API concepts, and basic web development principles. Familiarity with FastAPI, version control systems like Git, and experience using tools such as Docker or Postman are typically expected. Strong problem-solving abilities, eagerness to learn, and effective communication skills help interns collaborate and quickly adapt to new challenges. These skills and qualities are crucial for efficiently contributing to API development projects and succeeding in a fast-paced learning environment.

What is the difference between Internship Fastapi vs Junior Backend Developer?

AspectInternship FastapiJunior Backend Developer
Required CredentialsBasic programming knowledge, coursework, or self-study in Python and FastapiDegree in Computer Science or related field, some experience with backend frameworks
Work EnvironmentInternship setting, learning-focused, often in tech companies or startupsFull-time or part-time employment, collaborative team environment
Industry UsageEntry-level, training, and skill development phaseDeveloping and maintaining backend services in production

Internship Fastapi positions are designed for learners gaining hands-on experience with Fastapi and Python, often as part of an internship program. Junior Backend Developers are more experienced, responsible for building and maintaining backend systems in a professional setting. While internships focus on learning, junior roles involve applying skills to real-world projects.

Key responsibilities

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

  • 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.
