Python Developer / Software Engineer (m/f/d) – Test Automation, API, Multi-User Interface

Overview

We are looking for an experienced Python Developer / Software Engineer (m/f/d) to design and develop a flexible, multi-user capable Python interface for a next-generation radio frequency measurement system.
You will play a key role in modernising a C#-based test environment by developing a Python-driven control and evaluation framework that supports both manual and automated testing.
This is a full-time position based in Munich, Germany, with up to 60% remote work flexibility and a competitive salary between €70,000 – €90,000, depending on experience.

Position Details

• Salary Range: €70,000 – €90,000 gross annually (depending on experience)

Key Responsibilities

• Analyze and understand the current Analog/Digital measurement system (C#-based) used for manual and automated RF testing.
• Design and develop a Python-based interface that can control and evaluate the measuring system while ensuring data consistency with the existing C# system.
• Migrate existing test cases from C# to Python, ensuring compatibility and reliability.
• Validate and test the new Python interface for both manual and automated workflows, integrating with frameworks such as G5 and supporting future migration to DETECT.
• Architect a modular solution that supports on-the-fly Python scripting for extending or overriding standard processes.
• Develop a concept for multi-user operation, including rights management, script sharing, and collaboration features.
• Document all technical aspects, including API references, interface specifications, and user guides for a clear, developer-friendly experience.
• Plan and track development progress using Jira, applying agile and CI/CD practices for efficient delivery.

Required Qualifications
