Embedded C Developer for Bluetooth Stack

Contribute to the development of future connectivity solutions for hearing impaired. Join us and work with the latest embedded technologies connecting hearing aids to the digital world. Wireless communication is becoming ever more important to enable hearing impaired participate in society on equal terms. From using your hearing aids as a wireless headset, to connecting to a teachers microphone in the classroom, or simply getting a proper audio signal from your TV at home. We are looking for a colleague to join our development team located near Copenhagen to ensure we have the most versatile and stable Bluetooth solution.

Join our team

In our team, you will work on the low-level Bluetooth stack in our hearing instruments. We are responsible for the controller and host layers of the Bluetooth low energy protocol, enabling communication with all major phone brands as well as other accessory devices. The majority of our code is in C, using and contributing to the open-source Zephyr project. Our team is a mix of recent graduates and highly experienced engineers. We always work closely together and have collaborative reviews on all tasks to ensure both quality and knowledge sharing and you will get the best possible opportunity to learn and contribute. You will get a chance to work closely with colleagues in the hardware teams, other embedded software teams, as well as the phone app teams. Together, we are responsible for the full connectivity solution - a very complex and interesting task.

Ready to use your skills?

We consider both experienced and more junior candidates. It is important that you have a solid experience with embedded programming. Apart from that, if you are not an expert in all the areas below, we will get you up to speed. You should bring a passion to deeply understand your work area, learning new stuff, and communicating a lot with your colleagues. This is a fairly large development project, and you will become proficient in working on a large development pipeline involving many contributing teams.

Key Responsibilities:

  1. Develop and maintain the BLE stack, focusing on the controller and host layers.
  2. Implement unit tests and other automated tests.
  3. Collaborate with cross-functional teams to integrate BLE features into hearing instruments.
  4. Optimize code for performance, reliability, and power efficiency.
  5. Collaborate with third parties on interfaces to third party components and devices.
  6. Debug and resolve issues related to BLE connectivity and functionality.
  7. Stay updated with the latest BLE standards and technologies.

Qualifications:

  1. Bachelor’s or Master’s degree in Computer Science, Electrical Engineering, or a related field.
  2. Proven experience in C programming, particularly in embedded systems.
  3. Experience with microcontroller programming and real-time operating systems (RTOS).
  4. Solid understanding of Bluetooth Low Energy (BLE) protocols and standards.
  5. Good problem-solving skills and attention to detail.
  6. Ability to work in a collaborative team environment.

Onsite presence required

I Demant, we do have a hybrid work policy where a smaller part of your weekly work can take place from home. However, we are looking for a colleague who can be in the office every week, working directly with colleagues and interacting with equipment. Thus, remote work from abroad is unfortunately not an option.

Why apply…

You get to join a major company in its field and an organization with international footprint. We provide a collaborative and inclusive work environment and the opportunity to contribute to the commercial growth of our organization.

Get in touch

Please send your CV and motivational letter as soon as possible, as we are screening applications on a continuous basis. Please note that we only accept applications through our online recruitment system.
