Summary

Posted: Nov 11, 2026

Weekly Hours: 40

Role Number: 20

The MusicApps team in Rellingen, Germany, builds music creation and audio recording apps for Apple platforms. We are looking for a Software Development Engineer in Test who loves making and recording music. You will help us keep these apps at a high level of quality and performance on macOS, iOS, and iPadOS.

This is an on-site role at our office in Rellingen, Germany.

Description

You will test existing and new products, and you will build the automation and tools that help us ship with confidence. You will work closely with engineers, designers, and product managers. You will use our apps the way a musician does, and you will report what you find with clear steps and precise isolation.

You work in a careful, structured way. You communicate well, and you work well in a team. Details matter to you, and you do not accept "good enough”.

Responsibilities

• Test new features and run regression tests.
• Find and isolate issues across many software components.
• Run acceptance and integration tests on daily builds.
• Write, maintain, and expand automated tests and test tools.
• Use our products as a customer does, and report what you find.

Minimum Qualifications

• Programming or scripting skills, for example Python, shell, or Swift.
• Experience with QA processes, such as test planning, bug reporting, and regression testing.
• Experience with audio recording and Digital Audio Workstations (DAWs).
• Strong written and spoken communication skills in English.
• Close attention to detail. You find the small problems, and you do not accept "good enough”.

Preferred Qualifications

• Experience with test automation frameworks, for example XCUITest.
• Experience running automated tests.
• Knowledge of music theory and notation.
• Familiarity with MIDI, audio hardware, and audio interfaces.
• Bachelor’s degree in Computer Science, Software Engineering, or equivalent practical experience.

Because to create products that serve everyone, we believe in including everyone. Therefore, we are committed to treating all applicants fairly and equally. We will work with applicants to make any reasonable accommodations.

At Apple, we believe accessibility is a fundamental human right. You’ll find that idea reflected in everything here — in our culture, our benefits and our digital tools. By welcoming as many perspectives as possible, we help you build a career where you feel like you belong.
