Squarehead is looking for a C++ Developer to help us advance our world-leading acoustic systems.

We’re a small team in the software department who solve interesting problems in modern C++. Now we're looking for a new teammate to join us!

What you’ll do

Our main product is an array of 100+ microphones, which, combined with some clever maths and signals processing, enables us to listen in a direction. This allows us to detect and locate threats like drones.

The code that runs on the array is written in modern C++, where performance, clean code, safety, and collaboration really matter. The main responsibility of the code is to continuously sample the microphones, run the necessary DSP and machine learning algorithms, and turn this into detection information. This is then made available via network APIs, together with audio and video streams.

To make all of this happen, we use tools like C++23, CMake, Conan, clang-tidy, clang-format, sanitizers, IDEs of your choice, git and GitLab. And the best tool of all; talking to each other and getting stuff done.

The role is based in Oslo, Norway, more specifically in Nydalen, but working from home every now and then is not a problem. C++ experience as well as good written and oral communication skills in English are required. Any knowledge in TypeScript, Rust and CMake is a bonus.

If this sounds fun to you, and you have experience in some of what we have listed, send us an application describing how you can contribute. A bachelor’s degree or other relevant experience is an advantage when applying.

Squarehead Technology, who celebrated its 20th anniversary in 2024, is a global leader in directional microphone technology. The company was founded by three physics students at the University of Oslo who were intrigued by underwater sound waves. They came up with the idea of a microphone capable of separating intelligible sound from noise. Two decades later, Squarehead has grown into a team of 60 employees who develop, design, manufacture, and sell advanced microphone arrays.

Through the “digitalization of human hearing”, we enhance situational awareness in industrial and security sectors. Our solutions—ranging from drone detection and condition monitoring to quality control—play a vital role in safeguarding critical infrastructure and assets.

Squarehead is headquartered in central Nydalen, Oslo, with a subsidiary in the United States and sales representatives stationed across the globe. All development and production take place in Nydalen, fostering a dynamic and collaborative work environment. Being close to the final products means that challenges are solved together, across disciplines and expertise. At Squarehead, you witness the full impact of your work—from idea to implementation—and the difference it makes in the world.
