Job description

Senior Software Engineer - Hardware Abstraction Layer - Hearing Aids

Delivering software excellence and pushing the limits of technology to make some of the world’s best hearing aids is what we do in Demant.

We are looking for a Senior Software Engineer with broad competencies who wants to develop and strengthen our Hardware Abstraction Layer (HAL).

You will be deep down the software stack in a crucial and complex part of our software eco system.

Development, defect support and platform improvements

Our HAL platform connects to hearing aids, apps, fitting software and sophisticated internal tools. Seamless Bluetooth solutions and connectivity are crucial for the end-users to have great experience with our hearing aids.

We embrace agile software development and use Scaled Agile Framework (SAFe) and releases the HAL platform 2-4 times per year. The backlog of features and enablers are executed by priority.

The features are platform support of audiological or end user features. The enablers are typically platform improvements for the future and general internal improvements that can be either specific or of an exploratory nature.

What You Will Do

• Most of your daily life is analyzing, designing, coding, testing and integrating our platform, always done with a broad mindset. Analyzing logs and unraveling mysteries is a key activity in the role and team.
• With an ever-changing Bluetooth environment and incoming defects there will be adjustments, which you must react fast to as part of the team. You will also act as problem solver for other teams consuming HAL.
• Lastly, you will be part of simplifying HAL to make the solutions more effective, maintainable and secure. In collaboration with the team, you will identify improvements and come up with suggestions for how these should be implemented.

We need everybody in the team to be on top of technology to keep on improving and providing best-in-class solutions. To support this, we have a monthly learning day for the team to acquire relevant knowledge either individually or on a team base.

We invest in and take advantage of AI, that is part of our development environment and tooling.

Part of your team consists of six Software Developers, two Test Developers, a Product Owner and a Scrum Master. They are all very experienced and enthusiastic about their jobs.

We encourage and strive for T-shaping, meaning that it is healthy that we share the responsibilities and grow mutual skills between developers and test developers.

Scrum is used as the basic way of working and encourages collaboration, sparring and sharing of thoughts and enables the best possible solutions.

It is important that you can collaborate with others and see the gain of it, rather than just working on your own. We hope that you, with your energy and enthusiasm, will contribute and encourage cooperation.

Your manager is a “servant leader” and will support your needs and development in our trust-based culture.

We believe in the good life

In Demant we trust and value professionalism, experience, and commitment. We recognize that to bring energy and inspiration to work, you need to re-energize and spend time with family, friends, and hobbies in a healthy work life balance.

To ensure the good life we offer good breakfast and lunch in our canteen, free fitness room including weekly spinning and yoga sessions, massage offer, no child’s first sick day meaning you can stay home with your child as long as the child is not feeling well and the possibility to work from home up to two days per week. Just to mention some of the things.

Your profile

• To candidate for this job, you need to Senior Software Developer with minimum 8 years of experience. You have experience with hardware abstraction layers either as a provider or consumer.
• You are proficient in .NET and #C and have experience with Bluetooth Low Energy and/or have made apps; IOS, Android or MAUI, and are able to grasp, navigate and make a difference in a large eco-system of software and hardware.
• You like to understand how things work and to untangle complex issues in the complex HAL world.
• It will be nice but is not required if you have experience from pharma / medico or other regulated industries and know how it impact our work.
• Other people will say you have a high focus on quality and testing at all levels and that you enjoy the respect of others as a team player, where you seek the optimal solution through a constructive dialogue.
• It is required that you work on-site Smørum from 1st of January 2027 and no later than 1st of February 2027.

We expect to hold the 1st interview on the 16th and 18th of November, and the 2nd interview on the 23rd and 24th of November.
