Decagon is a conversational AI platform enabling enterprises to deploy AI agents for customer support and operations across voice, chat, email, SMS, and other channels. Customers include Avis Budget Group, Block's Cash App and Square, Chime, Oura Health, and Hunter Douglas.
As an Agent Experience Designer, you will shape what great AI conversation experiences look and sound like across channels and languages for enterprise customers worldwide. You'll work directly with customers and internal teams to improve agent quality, particularly in voice—one of Decagon's fastest-growing channels—and build systems and resources to scale expertise.
Key responsibilities include:
- Design and optimize enterprise-grade AI conversation experiences across chat, voice, SMS, and email channels
- Serve as a trusted advisor to customers and internal stakeholders on conversation design best practices
- Evaluate voice quality and interaction patterns to maintain high standards for naturalness and appropriateness
- Build repeatable frameworks for assessing conversation and voice performance
- Enable the Customer team to apply strong design judgment independently
- Partner cross-functionally with Engineering and Product to investigate quality gaps and drive improvements through clear recommendations
- Share learnings and create documentation on best practices to improve consistency and raise the quality bar across deployments
You'll need 5+ years of relevant experience in voice experience design, conversation design, product management, applied linguistics, or related fields. Hands-on experience with voice—conversational AI, speech synthesis, or audio production—is required. Experience migrating NLU systems to LLM, understanding RAG functionality improvements, and building evaluation frameworks or QA processes is essential. You must be a strong communicator across technical and business contexts and comfortable working close to the product in a fast-moving environment.
Desirable qualifications include native or professional fluency in Spanish and/or familiarity with other languages, experience with TTS providers or speech synthesis tools, and hands-on experience with frontier AI tools deployed in enterprise or high-impact settings.
Decagon is backed by a16z, Accel, Bain Capital Ventures, Coatue, and Index Ventures. The company is in-office, driven by shared commitment to excellence and velocity.
