Responsibilities
Own and build features end-to-end, from concept to delivery
Build agent-based AI pipelines, interfacing with ML engineers working on core models (e.g. our child speech recognition pipeline)
Serve as a bridge between product design and engineering, moving fluidly between UX/UI and technical problem-solving
Develop and integrate front-end components for mobile and web platforms, leveraging existing design systems and brand guidelines
Do whatever it takes to go from product conception to playtest
Qualification
Required
Excellent production-grade engineering & debugging skills across backend, ML, and mobile frontend
Experience with at least one of Flutter, native Android development in Java/Kotlin, or iOS development in Swift/ObjC
Experience with ML tooling and GenAI tools (you don't need to be a linear algebra beast designing your own models, but you should understand how multimodal models work and communicate with ML engineers in their language)
Some experience with GenAI models & pipelines, including human eval infrastructure
Familiarity with Git flow, etc
Basic data science skills (enough to analyze your own product insights)
Familiarity with basic infrastructure setup, continuous integration, and production release workflows
Very high level of attention to detail. For example, you see how small changes in a character's facial expression or the shading of a background affect the emotional impact of the end product
Demonstrated bias to action in product building: creating something from nothing and turning chaos into order
Demonstrated ability to work within existing design systems and brand standards to build new front-end components
Cross-functional skills; you likely either picked up engineering from a product/design domain or product skills from a computer science background
Familiarity with project management tools and collaborative development tools

Experience as a product manager or in a role with significant ownership over features or components
Deep understanding of mobile app architecture, design patterns, and performance optimization techniques
Experience with designing products for children
