Internship focused on the development of a transformation API and time series analysis for water data.
Key tasks: data transformations, quality checks, and extending Power BI dashboards.
Required: experience with Python, Pandas, Numpy, and basic knowledge of REST APIs.
Description
Internship focused on developing data flows, a transformation API, and preparing data for analyses and dashboards.
The project aims to quantify nitrous oxide (N₂O) emissions from wastewater treatment plants more accurately in order to reduce the climate impact.
Job requirements
- Background in bioinformatics, higher professional education in ICT, applied mathematics, or a related field; knowledge of biology is a plus.
- Interested in data and API development and strong analytical skills.
- Able to work independently and not afraid of dirty or incomplete data.
- Experience with Python, Pandas, and Numpy.
- Basic knowledge of REST APIs (e.g. FastAPI or Flask).
- Experience with Power BI and DAX is a plus.
- Knowledge of SQL and data modeling, and understanding of long versus wide data formats and efficient transformations.
Tasks
- Optimizing and making data streams robust, including converting long to wide format (silver layer).
- Normalizing time series with different frequencies and processing missing or delayed data.
- Developing a configurable method for parameters.
- Analyzing complex time series and calculating derivative values.
- Expanding the Power BI dashboard and implementing smart quality controls, such as flagging data anomalies and filtering calibration periods.
- Supporting researchers in extending the existing computing API and preparing data for use in Power BI.
Working conditions
- Work placement with allowance.
- A pleasant working environment with plenty of room for personal development.
- Gain practical experience with data analysis and Python.
- A friendly, diverse and multidisciplinary team.
- Free soup with lunch every day.
- The opportunity to gain experience in a socially relevant field.
Description of the organization
Innovative work and learning center for applied research into issues across the entire water chain.
