Description

You will join aduno®'s core development team and work at the interface between physical infrastructure and scalable software.
From LoRaWAN sensor data and MQTT pipelines to high-performance REST APIs - you'll bring the data to life.
You will design and implement scalable APIs and microservices using FastAPI - from data integration to secure endpoints.
Integration and processing of sensor data from LoRaWAN networks via MQTT and ChirpStack - you will ensure that no data point is lost.
Design and optimization of TimescaleDB schemas for time-series data; high-performance queries for large data volumes are your specialty.
Implementation of JWT-based authentication, refresh token strategies and modern authentication flows (including Redis session management).
Containerisation with Docker, helping to design CI/CD pipelines and deployment processes.
Developing and maintaining a testing strategy using pytest, mypy, and static code analysis tools (ruff, bandit) to ensure sustainable, secure code.

Proficiency in PostgreSQL or TimescaleDB; Understanding of time series data and query optimisation.
Proficiency in using containers for local development and deployment.
Knowledge of Redis (session management, caching).
Vertrautheit mit modernen Authentifizierungsstandards (JWT, OAuth 2.0, DPoP / RFC 9449).
Understanding of clean architecture and scalable system designs.
You take ownership of your components and proactively drive projects forward.
You can clearly communicate technical matters - both within the team and to stakeholders.
Clean code, sustainable solutions and meaningful tests are second nature to you.
You strike the right balance between perfection and time-to-market.
You enjoy sharing your knowledge, giving constructive feedback and working collaboratively to find the best solution.
You see IoT, network technologies, and new Python patterns as exciting areas, not as obstacles.

Several years' practical experience with Python 3.10+ and knowledge of object-oriented and functional programming.
Extensive experience in the development and design of RESTful APIs using FastAPI or a comparable framework (Flask, Django REST).
Knowledge of MQTT protocols and experience with processing real-time data streams.
Practical experience with pytest and writing unit and integration tests.
Experience with ChirpStack or other LoRaWAN network servers.
