Stellenbeschreibung

Do you want to build backend systems that really make a difference - and are you passionate about Python, clean architectures and IoT data? Then let's talk!

Ihre Aufgaben

• Backend development: You will design and implement scalable APIs and microservices using FastAPI - from data integration to secure endpoints

• IoT data pipelines: Integration and processing of sensor data from LoRaWAN networks via MQTT and ChirpStack - you will ensure that no data point is lost

• Database architecture: Design and optimisation of TimescaleDB schemas for time-series data; high-performance queries for large data volumes are your speciality

• API security: Implementation of JWT-based authentication, refresh token strategies and modern authentication flows (including Redis session management)

• DevOps integration: Containerisation with Docker, helping to design CI/CD pipelines and deployment processes

• Quality assurance: Developing and maintaining a testing strategy using pytest, mypy and static code analysis tools (ruff, bandit) to ensure sustainable, secure code,

• Modern tech stack: Python 3.12 , FastAPI, TimescaleDB, ChirpStack, Docker, GitLab CI - no legacy baggage

• Shaping the future: Your expertise matters - you have a real say in architectural decisions and the technical development of aduno®

• High-end equipment: Operating system of your choice - you decide what you work best with
