Agent UX Designer

About the Role

As part of the Agent Experience Design team, you'll help shape what great AI conversation experiences look and sound like - across channels and languages, for enterprise customers around the world. You'll work directly with customers and internal teams to improve agent quality - especially in voice, one of our fastest growing channels - and build the systems and resources that allow us to scale your expertise.

This work spans research, design, enablement, and product strategy. You might:

• Advise customers and internal teams on conversation design and voice selection
• Evaluate and iterate on voice quality across providers, languages, and use cases
• Build playbooks, rubrics, and evaluation frameworks that scale best practices across the team
• Partner with Engineering and Product to translate field insights into platform improvements

Your insights will shape how Decagon deploys AI in mission-critical contexts and how we build toward the next generation of intelligent systems.

In this role, you will

• 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 a high bar for naturalness and appropriateness
• Build repeatable frameworks for assessing conversation and voice performance
• Enable our Customer team to apply strong design judgment independently
• Partner crossfunctionally 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

Your background looks something like this

• 3-5+ years of relevant experience (e.g., voice experience design, conversation designer, product manager, applied linguistics, etc.)
• Experience building evaluation frameworks, rubrics, or QA processes
• Strong communicator across technical and business contexts
• Comfortable working close to the product in a fast-moving environment

Even better if you have

• Native or professional fluency in Spanish and/or familiarity with other languages
• Experience with TTS providers or speech synthesis tools
• Hands-on experience with frontier AI tools and deployment in enterprise or high-impact settings
