About the Role
We’re looking for a Conversational Designer with hands-on experience in voice bots and prompt engineering. This is a unique role where design meets AI - you’ll craft natural, engaging voice conversations while leveraging LLMs (like GPT-4, Claude, Gemini) and voice AI platforms (Retell, Vapi, ElevenLabs, Deepgram) to bring them to life. You’ll work at the intersection of conversation design, AI-driven prompts, and real-time voice automation, shaping the next generation of Voice AI experiences for our SaaS products.
What You’ll Do
● Design voice-first conversations that feel natural, human-like, and intuitive.
● Write, refine, and optimize prompts for LLM-powered voice agents handling real-time conversations.
● Map conversation flows, fallback strategies, and user journeys for voice bots and IVRs.
● Collaborate with engineers to integrate LLM prompts into voice AI platforms and APIs.
● Analyze call transcripts, recordings, and metrics to improve conversation performance.
● Balance UX empathy (tone, clarity, accessibility) with AI constraints (latency, interruptions, accuracy).
● Experiment with A/B testing, multilingual design, and new features to push the boundaries of voice AI.
● Document conversation specs, prompt libraries, and design decisions for consistency.
What We’re Looking For
● Proven experience as a Conversational Designer (voice bots, IVR, chatbots, or virtual assistants).
● Hands-on experience with LLMs and prompt engineering.
● Familiarity with voice AI platforms (Retell, Vapi, ElevenLabs, Deepgram) and API integrations.
● Strong writing skills - empathetic, clear, and adaptive to different voice personas.
● Ability to diagnose conversation failures and improve them with data-driven insights.
● Collaboration skills - comfortable working with engineers, product managers, and clients.
● Bonus: experience in multilingual voice design, A/B testing, or conversation analytics.

At KnackLabs, you’ll:
● Be among the first in India to pioneer voice AI design powered by LLMs.
● Work on a fast-growing SaaS product with real-world industry applications.
● Be part of a culture of experimentation, iteration, and impact.
● Grow at the crossroads of design + AI engineering, a rare and future-facing career path.
