Join us to put AI to work for people.

What you get to do in this role:

As a Senior Voice AI Engineer – Linguistics & Speech, you will

Contribute to the design, development and implementation of Voice AI applications, bringing linguistic and speech expertise to the core Voice Platform (Speech Recognition, Conversation Management, Speech Generation)

Own language support end to end: add new languages and locales, and maintain language-specific instructions, normalization and pronunciation rules.

Analyze complex speech problems across a diverse set of languages, accents and dialects

Work with other linguists to map the problem space of specific languages

Diagnose language and speech failures in production calls, trace them to the responsible component, and drive the fix with the team.

Partner with engineers to identify and solve the right linguistic problems, and contribute code to the features that power the user experience.

Partner with product managers to work with customers, understand their use cases and linguistic challenges, and build for their success

Design linguistic experiments that drive technology choices (e.g. STT/TTS models and vendors) for Voice AI applications

Build tooling, with the help of AI, to analyze linguistic problems at scale

Mentor colleagues and help promote knowledge-sharing across linguistics and Voice AI engineering disciplines

To be successful in this role you have:

A Master's or PhD in Linguistics, Cognitive Science, or a related field

A specialization in phonetics, acoustics, psycho linguist ics, or cognitive science (applied or interdisciplinary rather than theoretical linguistics)

4+ years of experience in large-scale experiment design and quantitative research projects in an industry setting or applied research

Hands-on experience building Voice AI applications

Development experience with Python or similar languages

Deep knowledge of the structure of several languages; fluency in a language other than English is a plus.

Ability to explain linguistic findings clearly to engineers, product managers, and customers.

Experience evaluating speech recognition and speech synthesis systems (considered an asset)

Experience building applications on top of LLMs, including prompt engineering (considered an asset)

A self-starter, outcome-driven mindset and the ability to work with many stakeholders

The ability to think critically about integrating AI into your work, including hands‑on experience with AI tools such as Claude Code, Cursor or Windsurf.
