Fullstack Developer - Python & React (m/w/d)

We are developing a modern, AI-supported process automation platform — from analyzing SAP workflows to automated generation of documentation and presentations. Our stack is consistently modern: Python 3.13, FastAPI, React 19, PostgreSQL, and Azure-Cloud-Infrastructure.

You will work closely in a small, agile team on a system that has a real impact on corporate processes — no buzzword bingo, but productive code that is in daily use.

Tasks

Backend (Python / FastAPI)

• Development and maintenance of REST APIs with FastAPI according to clear architecture patterns

• Database modeling with SQLAlchemy 2 and migration management via Alembic

• Implementation of tenantable data isolation with PostgreSQL Row-Level Security

• Integration of AI services: Anthropic Claude, OpenAI, Azure OpenAI, DeepL

• Development of Prefect 3 pipelines for asynchronous data processing

• Authentication via Azure AD / Microsoft Entra ID (JWT, JWKS)

Frontend (React / TypeScript)

• Building and further development of React 19 components with Material-UI (MUI v7)

• Type-safe API integration with openapi-fetch and automatically generated types

• State management with TanStack Query, routing with React Router v7

• Azure AD SSO integration via @azure/msal-react

Cloud & DevOps

• CI/CD workflows with GitHub Actions

• Deployment on Azure (Container Registry, Static Web Apps, Blob Storage)

Requirements

Prerequisites — you must bring this

• At least 1 year of experience with Python — you know type hints, async/await, Pydantic, and know how to write clean, readable code

• At least 1 year of experience with Azure — you have already worked with Azure services (e.g. Azure AD / Entra ID, Blob Storage, Container Registry, or Static Web Apps)

Advantage — not a must

• Knowledge of FastAPI or similar Python web frameworks

• Experience with React and TypeScript

• PostgreSQL knowledge, ideally with SQLAlchemy

• Experience with workflow orchestration (Prefect, Airflow, etc.)

• Integration of AI APIs (OpenAI, Anthropic, LangChain)

• Familiarity with quality tools like Ruff, mypy, or pytest

Personally

• You write code that you can still look at in two years

• You say when something doesn't make sense — and suggest a better solution

• You work independently and ask in time if you can't get any further

Benefits

• Modern, well-maintained codebase

• Direct communication, flat hierarchies

• Python 3.13 from day one

• Real influence on the architecture and tech stack

• Remote-friendly work culture
