AI Product Engineer (Mid/Senior)

About the Role

We're growing another team behind Lyro, our AI customer support agent, running on real, large-scale production traffic. Lyro is a sophisticated conversational AI that can:

• use custom tools
• follow complex, multi-step, user-defined Guidance
• access product data (through our native Shopify integration and an in-house system for ingesting products from any other source)
• access company policies
• continuously learn from company data and conversations

The same agent has to work for a solo store owner who sets it up in an afternoon and for companies with their own systems, their own processes, and very specific expectations about how support should sound. Building one product that does both - without it collapsing into a lowest-common-denominator bot - is the actual engineering problem here.

This isn't a classic role with a fixed lane. We're looking for a builder who takes full end-to-end ownership of things our clients actually see - from integrating with their systems to the agent engine itself, to the infrastructure that holds it all together. The brief you'll get might be just one sentence - scoping it, talking directly to the client, CSM, or sales team, shipping it, and iterating on it is on you. And sometimes there's no brief at all: you look at where the product stands, decide what would move it forward the most right now, and go make it happen.

This highly autonomous role is perfect for someone who thrives in a fast-paced environment, embraces spec-driven development, and enjoys leveraging AI tools to boost productivity.

What You'll Work On

• End-to-end feature ownership - from talking to the client, CSM, or sales team to shipping and monitoring in production
• Integrations and distribution channels for the agent
• The agent itself: context engineering, tool-use optimization, prompt caching, and an evaluation module used directly by clients and CSMs
• Working across the full stack, regardless of your specialization
