About the project

As a Software Developer, you will be part of an Agile team developing software solutions that integrate desktop and mobile applications with hearing instruments and related system components.

You will contribute throughout the software development lifecycle, from understanding requirements and designing solutions to implementation, testing, diagnostics and maintenance.

Quality is a shared responsibility in our team. You will be expected to verify your own work, contribute actively to code reviews and help improve our codebase, testing practices and ways of working. You will also use AI tools to support development and problem-solving while critically verifying their output.

• Apply practices such as TDD, BDD and Agile Testing.
• Work with asynchronous and concurrent code, including async/await, multithreading, race conditions and deadlocks.
• Investigate software issues using logs, perform root-cause analysis and resolve defects.
• Review requirements and contribute to technical and design decisions.
• Use AI-assisted development tools responsibly and verify generated code and answers.
• Collaborate with the team, participate in Agile activities and contribute to continuous improvement and innovation.

• Experience working in an Agile environment such as Scrum or SAFe.
• Good written and spoken English.
• A respectful, collaborative approach and willingness to continuously develop your skills.
• A degree in Software Engineering, Computer Science or a related field is welcome, but comparable practical experience is equally valuable.
