Job Description


We are looking for a passionate and talented machine learning engineer with a particular interest in working on speech and audio technology. As part of our Speech & Audio team you will work alongside scientists and engineers to implement, deploy and maintain systems that will directly impact users in the public safety and commercial domains in the form of products and services that make use of speech and audio technology. This role requires skills in working with both science and engineering tools and environments to train models and realize them in working demonstrations and production.

More specifically this involves:

  • Implementing and improving our audio pipelines for training, inference and evaluation.

  • Developing modeling tools, training recipes and prototypes utilizing programming skills in Python.

  • Conducting experiments to assess the quality of speech recognition and natural language processing models and to study the effectiveness of different modeling techniques.

  • Analyzing field data in order to identify areas of possible improvement or enhancement of the system.

  • Presenting and discussing ideas and results within the team and with internal stakeholders (product/project management, engineering etc.).

  • Writing technical documentation.

As part of the team, you will implement and optimize novel machine learning algorithms for sound classification, speech recognition and audio context understanding. Our team is involved in the entire machine learning life cycle – from data collection, model development to inference and deployment, bringing with it unique opportunities to develop new holistic ideas in the domain and deliver a better experience for our customers.

We’re excited about the work we are doing in AI. We often describe it as “Mission Critical AI” because our approach is founded on our many years of Public Safety experience and knowledge. We know the mission-critical needs of our customers are unique and different from the consumer technologies that leverage AI today.

  • Be an avid programmer, with extensive expertise in Python or C/C++
