Junior Python Backend Developer

Smart Steel Technologies Berlin Full-time

At Smart Steel Technologies, we are building a one-of-a-kind cross-disciplinary team, uniting the worlds of steel and machine learning. Our team has come together from a diverse set of academic and professional backgrounds: software development, computer science, mathematics, physics, and metallurgy. Our goal is to leverage this expertise through trust and cooperation. We want to foster an environment where team members have frequent opportunities to learn from each other in fields that they are not (yet) experts.

The machine learning and data science we employ comes in several varieties: image processing, signal processing, classical supervised modeling, unsupervised methods, exploratory data analysis, and fundamental statistics and probability.

We are grateful to stand on the shoulders of the open source giants. We use NumPy-flavored Python3 as the basis for our development, taking advantage of the availability of libraries designed for both software engineering and data science, ranging from Flask to SciPy, SQLAlchemy to Keras, Jupyter to Pandas, and many more. When Python’s time or space complexity becomes a constraint, we turn to modern C++. When we require client-side browser-based interactivity, we turn to JavaScript. As a python backend developer, your specific expertise as well as your motivation would be the major factors in determining your day-to-day work.
