• Continuously improve our brand onboarding and operational excellence capabilities.
• Collaborate with product and design teams to build world-class applications.
• Work on systems that handle millions of voice AI conversations per year.
• Identify and eliminate sources of toil and inefficiency in systems and processes.
• Proactively refine UX based on user feedback and usage analytics, driving measurable improvements in adoption, task completion time, and error rates.
