Software Engineering Intern (Full-Stack)

About the Role

As a Software Engineering Intern at SANOVIO, you’ll get hands-on experience building the AI-powered procurement infrastructure that tackles one of the biggest and most complex cost problems in European healthcare.

This is a fast-paced, hands-on role for aspiring engineers with high agency, strong technical curiosity, and a builder mindset. We’re looking for a full-stack generalist with a frontend affinity. You’re eager to design user flows and implement them in React and TypeScript, while learning to own outcomes end-to-end across backend, data, AI-enabled workflows, and cloud deployment. You thrive amid uncertainty, move quickly, and care deeply about writing clean, high-quality code.

If you are a passionate builder who thrives at the intersection of full-stack development and AI, this is your opportunity to work directly with the founders, contribute to a real product, and grow rapidly in a startup scaling toward €10M ARR in 2026.

TASKS

• Contributing to end-to-end product workflows, from frontend UX to backend systems, data pipelines, and edge cases
• Building frontend experiences in React and TypeScript alongside scalable, reliable backend systems
• Supporting the design and development of AI-enabled systems, including embeddings, retrieval, and agents that create real operational leverage
• Working on data pipelines for large-scale unstructured data
• Making pragmatic technical decisions on architecture, tools, and frameworks to balance speed and quality
• Deploying and maintaining software in cloud environments with a “you ship it, you run it” mindset
• Writing clean, maintainable, and well-tested code with scalable, reusable components and APIs
• Collaborating across the stack and learning through code reviews, pair programming, and mentorship from senior engineers

REQUIREMENTS

We are looking for ambitious engineering students or recent graduates with a strong foundation in software engineering and a genuine interest in AI. We hire for skill, ownership, and output.

General Profile

• Generalist mindset with a frontend affinity, eager to build across backend, data, and AI
• Proactive and self-driven, able to turn unclear requirements into shipped software
• Fast learner who picks up new technologies and frameworks quickly
• Comfortable iterating closely with users and clients, including across different cultures
• Strong problem-solving ability and attention to detail
• Motivated to build excellent software in a fast-paced startup environment
• Willing to work in-person in Munich with a higher intensity than a traditional 9–5 role

Technical Skillset

• Solid foundation in full-stack software engineering, especially React and TypeScript, with a good understanding of constructing user flows
• Backend engineering skills, ideally with Node.js, and familiarity with APIs and data modeling
• Experience building software projects (academic, personal, or professional)
• Familiarity with Docker and cloud environments is a plus
• AI experience is a plus, especially embeddings and retrieval, structured outputs and tool calling, evals, and agentic workflows beyond prompt engineering

Communication & Ownership

• You take initiative and enjoy taking responsibility for your work
• You communicate clearly and are comfortable interacting with technical stakeholders and clients
• You actively seek feedback and want to improve rapidly

Bonus if you

• Can share a portfolio of projects, shipped products, or a GitHub with meaningful work
• Have built workflow-heavy B2B products, internal tools, or operations software

BENEFITS

• Great central office in Munich with regular team events and dinners
• Monthly Wellness budget
• Access to any AI or productivity tools you need to do your best work
• International scope & travel
• Flexible work setup with time-zone responsibility
• Full-time offer opportunity

About the interview process

Step 1: Intro Call

Casual intro meeting with one of the founders to get to know each other and introduce SANOVIO.

Step 2: Technical Interview

The technical interview consists of two parts:

• A take-home exercise, including a short presentation
• A system design interview

For the take-home exercise, we’ll provide you with a task focusing on a real SANOVIO workflow and user flow in React and TypeScript, with a light end-to-end angle such as API integration, data modeling, edge cases, and clean architecture. Later, you’ll present your results to us.

Step 3: Personal Fit

Meet another co-founder to get a feel for our culture and working style.

Step 4: Offer

If we see a great fit, you’ll receive an offer.

We’re excited to see your application and get to know you!
