Build Amazing - Deliver Amazing - Live Amazing - Be Amazing

We are looking for an expert at the intersection of linguistics and voice interaction design to help design and implement advanced AI voice agents on our platform. As a Senior Voice AI Designer, you will define the voice and conversational experience of our AI assistant from the ground up. You will craft natural dialogues, optimize language understanding, and work cross-functionally with engineers to bring human-like voice interactions to life. This role is highly impactful – your work will directly influence how thousands of businesses and users communicate using Nextiva’s AI. 

Key Responsibilities 

• Conversational Design: Create intuitive voice conversation flows and dialogue scripts for our AI assistant. Define user intents, sample utterances, prompts, and error recovery paths that enable users to achieve their goals naturally and efficiently. 
• Linguistic Optimization: Apply your linguistics expertise to tune the AI’s language understanding and responses. Expand the system’s ability to manage diverse phrasing, accents, and conversational nuances (including context carryover and user interruptions) without needing explicit definitions. 
• Cross-Functional Collaboration: Work closely with product managers and AI engineers to implement your conversation designs. Fine-tune the speech recognition (ASR), natural language understanding (NLU), and text-to-speech (TTS) components of the voice agent by providing requirements and iterative feedback. Ensure the technical implementation aligns with the intended user experience. 
• User Testing & Iteration: Conduct usability tests of the voice agent (e.g., prototype dialogues or beta features) and analyze real user interactions. Identify pain points or misunderstandings and refine the dialogue flow, wording, or underlying NLU models to continuously improve success rates and user satisfaction. 
• Voice UX Best Practices: Establish conversation design best practices and standards. Implement effective turn-taking cues, confirmations, and personality-consistent responses for the assistant. Champion a user-centric voice that is friendly, professional, and reflective of Nextiva’s brand, without over-explaining technical details to users. 
• Innovation: Stay up to date with the latest trends in conversational AI and voice UX. Experiment with new tools or approaches (e.g., leveraging large language models for dialogue, improving multi-modal voice + screen interactions, etc.) and incorporate relevant innovations to keep our AI voice agents on the forefront. 

 Qualifications 

• Experience: 4+ years of hands-on experience designing voice or conversational interfaces (voice assistants, IVR systems, chatbots, etc.). You have led conversation design for at least one significant product or feature from concept to launch. 
• Domain Expertise: Strong background in Voice UX/Conversation Design and/or Computational Linguistics/NLP. Deep understanding of how people naturally communicate and how to design AI interactions to match that. 
• Technical Skills: Familiarity with speech and language technologies – experience working with ASR, NLU, and TTS systems is required. Proficiency in using conversational AI platforms or tools (e.g., Dialogflow, Amazon Lex, Microsoft Bot Framework, or similar) to build or prototype dialogue flows. 
• Basic programming or scripting skills (Python or similar) to manipulate conversational data or tweak prototypes. 
• Linguistic Skills: Solid grasp of linguistic concepts (grammar, semantics, pragmatics, phonetics) and ability to apply them to improve language understanding in AI. You can craft dialog that accounts for diverse ways users might phrase things, without needing each variation explicitly spelled out. 
• Communication & Collaboration: Excellent communication skills with the ability to document designs clearly and explain reasoning to diverse stakeholders (engineering, product, customer support, etc.). Proven ability to work in cross-functional teams and iterate based on feedback and user data. 
• User-Centric Mindset: Empathy for end-users and a strong desire to create delightful, frictionless voice experiences. A mindset of continuous improvement – you iterate until the conversation feels as smooth as talking to a helpful colleague. 

Preferred Qualifications (Nice to Have) 

• Experience with advanced conversational AI techniques, such as leveraging large language models or retrieval-based methods to enhance dialogue management. 
• Background in telephony or contact center voice applications (e.g., designing IVR call flows or voice bots for customer support). Understanding of call center metrics and workflows is a plus. 
• Multilingual conversation design experience – e.g., designing voice interactions in multiple languages or accommodating various accents/cultures. 
• Active involvement in the conversational AI or linguistics community (publishing articles, speaking at industry events, participating in groups like Voice UX meetups or the Conversation Design Institute).
