Job description

What you can expect

We are looking for a Product Engineer focused on customer deployments for Agentic Voice AI to lead the deployment of next generation Zoom Virtual Agents. Leveraging LLMs and agentic frameworks to build highly automated conversational voice and chat agents for strategic customers.

You would be expected to have native language proficiency in English as well as one or more languages such as, German, French, Spanish, Japanese, Arabic languages.

About the Team

The Zoom Virtual Agent team is dedicated to building state-of-the-art conversational AI solutions that resolve customer issues quickly and efficiently. Play a critical role in developing metrics, intelligence, and evaluation systems that drive continuous improvement using advanced LLMs and data science.

Responsibilities

• Leading multi-step conversational workflow design using agentic frameworks to enable LLM agents to execute complex multi-tool tasks, including database checks and transactions.


• Fine-tune the underlying Large Language Models (LLMs) to ensure optimal performance, low latency, and minimal hallucination in real-time voice conversations.


• Developing and deploy custom full-stack Python/JS to connect the agent's decision-making with customer back-end systems (CRM, ERP, knowledge bases) as external \"tools.\"


• Crafting and iterating advanced LLM prompts (e.g., chain-of-thought, few-shot) to guide conversation, maintain context, and ensure accurate tool use in live voice interactions.


• Prompt-engineer TTS components (e.g., ElevenLabs, Azure, Cartesia ) to fine-tune tone, pacing, emphasis, and prosody to context and brand.


• Conducting A/B testing and performance monitoring on TTS output, ensuring high acoustic quality, latency requirements, and emotional appropriateness.


• Acting as the embedded technical expert, working directly with customer engineering and executive teams to map complex business goals to agentic solutions.


• Managing end-to-end production deployments with continuous optimization and performance tuning driven by real-world voice traffic data.


• Translating field challenges, LLM failure modes, and TTS needs into actionable input for Core Engineering and Product to drive platform innovation.

What we’re looking for

• Have 3+ years in a technical, customer-facing role (FDE, Solutions Architect, Technical Lead) focused on AI/ML or highly technical SaaS products.


• Possess proven hands-on experience designing and deploying LLM solutions using modern agentic frameworks (e.g., LangChain, LlamaIndex, internal tools).


• Have deep expertise in voice stacks and TTS integration, using prompt engineering to control prosody, tone, and pacing.


• Possess proven ability to write and manage iterative prompts guiding both generative text logic and speech synthesis quality (prosody and emotion).


• Have solid software development skills in Python for prototyping, API integration, and production deployment, coupled with familiarity with modern DevOps practices.


• Own exceptional ability to distill complex AI and engineering concepts into clear, actionable insights for both technical teams and C-level executives.
