The position offers a chance to work in a collaborative environment where machine learning and signal processing come together in solving real life engineering problems. Responsibilities Curate, organize, and maintain high quality audio datasets for machine learning applications. Train, evaluate, and improve machine learning models for audio event classification and detection, including drones and other acoustic targets. Analyze model performance and enhance performance and robustness under challenging acoustic conditions Collaborate closely with scientists and engineers in signal processing, acoustics, and data science. Support data labeling, validation, and experiment design for ML development. Research and apply relevant machine learning methods for audio and acoustic data. Required Qualifications MSc or PhD in Machine Learning, Computer Science, Signal Processing, Electrical Engineering, Physics, or a related field. Experience in training and evaluating machine learning models. Strong Python programming skills and experience with ML frameworks such as PyTorch or TensorFlow. Good understanding of classification, detection, and model evaluation techniques. Ability to work independently and collaboratively in multidisciplinary teams. Strong analytical and problem solving skills. Fluent written and spoken English. Personality & Interests We value curiosity, creativity, teamwork, and the ability to work independently when needed. We are looking for you with strong analytical skills, a genuine interest in machine learning for audio, combined with strong coding skills and the motivation to build robust, reliable systems. Workplace & Benefits Working in R&D at Squarehead means working at the intersection of machine learning, DSP, acoustics, and real world systems. The company develops advanced acoustic sensors that have to perform reliably in demanding environments, which creates interesting challenges across everything from signal processing and ML models to embedded deployment and large scale sensor systems. In addition to the above, we offer: Employee development through conferences and courses. Easy commute right next to the subway. Subsidised canteen. Weekly organized physical activity (currently padel tennis and climbing) Rooftop terrace for breaks and summer parties Indoor bicycle and car parking Wardrobe with showers Practical We work with partners who require confidentiality and have security requirements that we must ensure our employees can comply with. This position may require security clearance. Om bedriften 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 70 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. Sektor Privat Nettsted http://www.sqhead.com/
