At our company you won’t be building flashy websites — you’ll be the interface between our robust hardware and the end user.
Your work will have a direct impact on our products — from the Android connector app to future projects such as a PC control center or a companion app for industrial smartwatches.
Develop Windows and Android applications (e.g., C++/C# and Java) to interact with our hardware
Implement hardware-near features such as reading system/device data, interacting with interfaces, and background processes
Establish pragmatic release/update processes, versioning, and clean delivery
Independently execute software projects — from concept to implementation — this responsibility lies with you
Work closely with product management to implement requirements

You can independently deliver software from “requirements” to “stable operation.”
A university degree (Computer Science or similar) or training as an application developer is not strictly required if you are a highly skilled self-taught developer with demonstrable abilities.
You are at home in C++/C# (Windows) and Java/Kotlin (Android) and enjoy system-level development (services/background, interfaces, debugging)
Hardware affinity: you understand what drivers are, how system services work, and you’re comfortable communicating with physical devices.
Mindset: you are a doer. If you get stuck, you don’t wait for help — you research, test, and solve the problem (Stack Overflow & AI are tools you use).
Flexibility and initiative: you are pragmatic, learn quickly, document sensibly, and approach problems in a structured way
Language: your code and comments are in English. You speak fluent English (C2). German is useful for informal office communication but not required; Chinese is a plus.

Permanent employment contract in a future-oriented industry
Modern workspaces in the heart of Karlsruhe
Flexible working hours and vacation arrangements
Hybrid option: after the probationary period, work from home 2–3 days per week on request
Real responsibility: you will effectively build the software department here “from scratch.”
Open doors, flat hierarchies, and a first-name culture
Individually tailored support measures for continuous development (e.g., later progression into Embedded Development)
Short decision-making paths and open communication
We care about environmental and climate protection — we cover the cost of the Deutschlandticket
We succeed together, so employees participate in the company’s profits
No on-call duty or business travel
