About the role
Cloud Studios is a Berlin app studio building premium, productised digital products. Our current product, GetMOW, analyses how AI engines like ChatGPT, Perplexity and Google's AI Overviews represent B2B software brands, and tells companies what to change to get recommended.
We need to move the core of this product from "working prototype" to a system that runs reliably at scale. That's this role.
You'd own the backend: the system that queries multiple AI platforms, processes what comes back, and turns it into structured insight. We have the product logic worked out. What we need is an engineer who can turn that into infrastructure that doesn't break under real usage.
Secondary to that, you'd also implement UI work from our product designer's designs and clean up parts of the existing frontend. The majority of your time goes to the backend and AI systems.
Tasks
Design and build the backend architecture for GetMOW's AI analysis engine: orchestration across multiple AI platforms, data pipelines, job scheduling, storage
Build AI workflows that hold up under real load - structured, tested, monitored, with clear failure handling
Set up the security and infrastructure basics: authentication, data handling, error handling, logging
Use AI coding tools (Claude Code or similar) to build fast, while understanding and owning what ships
Implement UI features from Figma designs and refactor parts of the existing frontend codebase
Take technical decisions independently and be able to explain them
Requirements
Strong backend fundamentals: APIs, databases, async processing, system design
Practical experience building with LLMs or AI workflows: API integrations, structured outputs, multi-step pipelines, evaluation, or similar. Coursework alone isn't enough, we need something you've actually built
Familiarity with our stack or something close to it: Next.js, TypeScript, Supabase, Vercel
A habit of writing secure, maintainable code, not just code that runs once
You use AI tools to increase your speed, not to replace understanding your own system
Fluent English
Eligibility
You must currently be enrolled at a university or in vocational training, and one of the following must apply:
1. Mandatory internship (Pflichtpraktikum): required by your study or training regulations. You'll need your enrollment certificate and proof of the requirement.
2. Voluntary internship alongside your studies: maximum 3 months
Applications that don't meet either condition can't be considered, regardless of how strong the technical fit is.
Benefits
You'll own a production system from the start, not a peripheral feature
Direct, regular contact with the founders on technical and product decisions
A real, live product you can point to afterward, not a toy project
If it works out, a path to a long-term paid role with continued ownership of what you built
Details
Duration: 3-6 months (mandatory internship) or max. 3 months (voluntary internship)
Full-time, 30-40h/week
Berlin office preferred, ideally 2+ days/week. Remote is possible
Start: as soon as possible
This internship is unpaid, in line with the legal conditions above
Towards the end of the internship, we'll discuss extending into a long-term, paid role based on performance and fit
