Introduction
High availability with zero downtime, 100% data encryption, and high-performance data access - these are some of the features of the IBM Z Enterprise Computing Platform, also known as the IBM Mainframe.

In our development center in Böblingen, we work with the latest methods on central components of the IBM Z firmware. With our hardware-oriented development, which represents the software interface for the future IBM Z processor generation, we shape cutting-edge technologies at the highest quality level.

Your Role and Responsibilities
We are creating IBM Z Millicode to control basic hardware functions. This code is the link between the concrete hardware implementation and the abstracted IBM Z processor architecture, ensuring that important hardware functions can be efficiently addressed by the operating system.

• Implementing system processes and microfunctionality using assembler programming
• Ensuring the highest reliability and best runtime behavior
• Contributing and expanding the IBM Z architecture
• Writing test cases and executing them, e.g. by using simulated hardware
• Error analysis and troubleshooting in complex scenarios
• Supporting the introduction of new processor systems

• Completed Bachelor's/Master's degree in Computer Science or a comparable technical field
• Be curious and have fun to learn!
• Interest in assembler programming
• Profound knowledge of procedural/imperative programming
• Profound knowledge of at least one scripting language, preferably Python
• Communicative and enjoy working in an agile and international team
• Language Skills: English - Fluent

• Good knowledge of agile software development
• Experience with Git
• Base knowledge of Computer Architecture / CPU Architecture
• Good knowledge in C/C++ or Assembler programming
• Language Skills: German - Advantageous
