## Description

As an AI Engineer: Voice Designer at Dialpad, you'll own the back-end implementation and linguistic optimization of the Text-to-Speech (TTS) layer for next-generation AI voice agents.

You'll work within the Speech Team, a high-impact R&D and engineering group focused on speech recognition, enhancement, and synthesis. Your goal will be to bridge the gap between core speech science and product engineering, ensuring voice agents sound human, context-aware, and trustworthy.

Responsibilities:

- TTS Backend Implementation: Integrate and optimize multiple TTS vendor APIs, lead research and prototyping for open-source or in-house TTS architectures.

- Linguistic Optimization: Apply phonetics and sociolinguistics expertise to format TTS input for maximum naturalness.

- Conversational Turn Design: Craft context-specific utterances to optimize turn handling and build caller trust.

- Prompt & Persona Management: Design and manage LLM and TTS prompts and parameters to define and refine agent personalities.

- UI Parameter Exposure: Architect logic to expose voice attributes to the product UI.

- Cross-Functional R&D: Partner with ASR and Audio AI engineers to ensure end-to-end voice quality and minimize latency.

Requirements:

- Strong Python programming skills and experience with deep learning frameworks (e.g., PyTorch).

- 3+ years of experience in Speech Synthesis (TTS) or Voice Design.

- Degree in Computational Linguistics, Computer Science, or AI/ML with a deep understanding of phonetics, prosody, and syntax.

- Proven experience crafting and evaluating LLM prompts and managing structured prompt templates.

- Experience building production-grade APIs and integrating multi-vendor services in a cloud environment (GCP preferred).

The target base salary range for this position is $145,000-$172,500 CAD.

Benefits include competitive salary, comprehensive benefits, and real opportunities for growth.
