Key job responsibilities
As an Applied Scientist, you should be a strong communicator, able to describe scientifically rigorous work to business stakeholders of varying levels of technical sophistication. You will closely partner with the solution development teams, and should be intensely curious about how the research is moving the needle for business. Strong inter-personal and mentoring skills to develop applied science talent in the team is another important requirement.
- Lead research and development of speech and audio generation technology and end-to-end speech-to-speech architecture
- Develop audio processing solutions for production environments, including source separation, enhancement, and mixing
- Define the research roadmap for your area, identify high-impact problems, and communicate technical direction to senior leadership
- Publish research, contribute to the broader scientific community, and bring external advances into production systems

A day in the life
You might start your morning reviewing experimental results and refining a model architecture before syncing with your engineering partners on integration plans. After lunch, you could be whiteboarding a new approach to a problem your team recently identified, then writing up findings for an internal science review. You will regularly present your work to peers and stakeholders, participate in code and design reviews, and explore emerging research that could unlock new possibilities for your team.

About the team
Our team is driven by a shared commitment to applying science in ways that create meaningful impact for customers. We value rigorous research, collaborative problem-solving, and a willingness to experiment with new ideas. You will work alongside talented scientists and engineers in an inclusive environment where your contributions shape the direction of our work. We are focused on building solutions that matter at scale, and we are looking for teammates who are energized by that challenge.

Questions you could be asked

What NLP problem have you worked on, and how did you measure whether it actually worked?
What have you built with speech recognition or text-to-speech, and where did it break?
Tell me about a project where machine learning was part of your work. What did you do?
Tell me about a project where speech synthesis was part of your work. What did you do?
Tell me about a project where audio processing was part of your work. What did you do?

Adapt your resume

List these exact terms on your resume: Nlp, Speech, Machine Learning, Speech Synthesis, and Audio Processing. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them — a tool named with nothing behind it rarely survives a human read.
Lead with what you built, trained or shipped — this role is judged on the AI system itself, not the tools around it.
