Senior Product Engineer, Ello

• You pay attention to the details and thrive building products that delight users
• You can work full-stack and across multiple programming languages, build chains, etc. Learning yet another language doesn’t feel like a daunting task at this point
• You have experience with or a demonstrated curiosity for GenAI pipelines
• On the backend, you’re able to write performant Python code and deal with complex I/O pipelines
• On the frontend, you’re able to take an existing component library and build a rough UI from scratch (Flutter & React) without a designer or implement pixel-perfect layouts in collaboration with a designer
• As an ideal candidate, you’ll have built and shipped software products end-to-end in the past, for example through an initiative you championed at a prior job, through an impressive side project, or as the founder of your own company. We’d love to hear about those in the interview process!
• 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
• Have something to teach us
• Want to do work they are proud of to ship products they are proud of
• Have an urge to make a real impact on child development at scale
• Take initiative and full ownership of their work
• Prefer open and direct communication grounded in empathy to beating around the bush
• Exemplify integrity in their actions, decisions, and communication
• Want to build meaningful relationships at work

Desirable

• Ello is a rapidly growing, series A startup focused on revolutionizing the way children learn and interact with technology
• You will work directly with Ello’s Co-founder & CTO, Catalin Voss, on a small team (<10) of engineers, learning designers, and PMs to develop new products
• You’ll be surrounded by a team of A+ engineers and you’ll work with some of the foremost experts in ML to productionize models and build new product experiences
• We’re looking for a strong Sr. Product Engineer, New Products to independently own the build-out of learning activities as part of Ello’s next-generation AI tutoring apps
• You will bridge the gap between product development and engineering to own features from conception to playtest, at times acting as your own product manager, and at times collaborating closely with our product team
• You’ll be part of a small team that is responsible for bringing Ello’s tutoring AI to life through agent control, character development, and game interactions
• 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
