AI Engineer (Agentic Voice, TTS)

Join our Speech Team as an AI Engineer, where you'll be responsible for the back-end implementation and linguistic optimization of the TTS layer for our next-generation AI agents. You'll work closely with our Voice Experience Designer and other engineers to create a human-like, context-aware voice for our AI agents. This position is based in Vancouver and operates on a hybrid schedule.

• Responsable de l'implémentation backend et de l'optimisation linguistique de la couche vocale (TTS) pour les agents IA de prochaine génération.
• Intégration et optimisation des API de plusieurs fournisseurs TTS derrière une interface unifiée, et recherche et prototypage d'architectures TTS open-source et internes.
• Minimiser le temps jusqu'à la première audio et la latence de bout en bout dans le pipeline ASR → LLM → TTS tout en maintenant ou en optimisant la qualité vocale.
• Speech expertise: 3+ years in Speech Synthesis (TTS) or applied speech ML, including hands-on work with frameworks like NVIDIA NeMo, ESPnet, or Coqui, and with major TTS APIs such as ElevenLabs, Rime, and Cartesia
• Technical foundation: Strong Python and hands-on experience with deep learning frameworks (e.g. PyTorch)
• Linguistic background: Degree in Computational Linguistics, Computer Science, or AI/ML, with a strong understanding of phonetics, prosody, and syntax you can apply in code (G2P, pronunciation dictionaries, text normalization)
• Evaluation mindset: Fluency with speech-quality metrics (MOS, intelligibility, latency) and the ability to design and execute rigorous A/B tests for voice personas
• Prompt engineering: Proven experience crafting, versioning, and evaluating LLM prompts (system, few-shot) and structured templates
• Backend engineering: Experience building production-grade APIs and integrating multi-vendor services in a cloud environment (GCP preferred)
• Don’t meet every single requirement? If you’re excited about this role and possess the fundamental traits, drive, and strong ambition we seek, but your experience doesn’t meet every qualification, we encourage you to apply
