About the role

Key responsibilities & impact

Develop Windows and Android applications that interact with our hardware.
Implement low-level hardware-related functionality such as reading system/device data, interfacing with external connections, and handling background processes.
Establish pragmatic release/update processes, versioning, and reliable delivery.
Independently own software projects — from concept to implementation.
Work closely with product management to translate requirements into solutions.

Requirements

What you’ll need

A degree in Computer Science (or similar) or vocational training as an application developer is not strictly required if you are an outstanding self-taught developer with demonstrable skills.
You are comfortable with C++/C# (Windows) and Java/Kotlin (Android) and enjoy system-level development.
Hardware affinity: you understand drivers, how system services work, and are comfortable communicating with physical devices.
Mindset: you are a doer. If you get stuck, you don’t wait for help — you research, experiment, and solve the problem.
Flexibility and initiative: you are pragmatic, quick to learn, document sensibly, and approach problems in a structured way.
Your code and comments are in English. You speak fluent English (C2). German is useful for casual office communication but not required. Knowledge of Chinese is a plus.
