About the role
As an AI Experience Developer, you will oversee the full lifecycle of customer-facing journeys powered by Upgrade's conversational AI across chat, voice, and email. Working with Sierra Agent Studio and backend APIs, you will translate operational service flows into automated production experiences, monitor transcript quality, handle edge cases, and continuously drive customer satisfaction and self-service resolution rates.
What you'll do
- Design and develop conversational journeys in Sierra Agent Studio for chat, voice, and email channels
- Analyze transcripts, recordings, and analytics weekly to identify conversational drop-offs and implement logic/prompt fixes
- Map edge cases and ensure appropriate handoffs or resolutions for issues such as declined payments and mismatched identities
- Partner with product and engineering teams to define API requirements and integrate service flows into the AI agent
- Build simulation and regression testing suites to ensure journey updates do not degrade existing behaviors
- Monitor latency, error rates, and fallbacks using SumoLogic and Grafana, managing production alerting
What you bring
- 3 to 5 years of experience in software development, technical solutions, conversational AI, or technical product management
- Hands-on understanding of LLM agent behavior, prompting, tool calling, knowledge retrieval, and failure modes
- Experience designing evaluation systems for non-deterministic software (simulations, test suites, LLM-as-a-judge)
- Technical fluency to read API specifications and collaborate with backend developers on REST and GraphQL integrations
- Strong product and customer mindset with a disciplined approach to production monitoring and incident response
