Senior Product Engineer

Company details

Description of the offer

At Ello, our mission is to maximize the potential of all children. Our first product, Read with Ello, is an AI reading teacher that listens to children read out loud. Ello uses speech recognition to help them when they get stuck, makes up stories using generative AI, and inspires a love for reading.

We’re now building on the success of Read with Ello and putting together the pieces of the world’s first complete AI teacher for all children. Together, we believe we can close the primary school education gap worldwide.

Ello has been recognized on Fortune’s “Change the World” and Time’s 2024 Best Inventions lists. We are well-funded, backed by world-class investors, and ready to recruit new talent to help us achieve our vision.

Who you’ll be joining

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 work in-person out of our San Francisco office and we’re big believers in face-to-face collaboration.

About the role

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. 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.

We welcome candidates from all backgrounds – mobile engineering, machine learning, or design & product – but we prioritize strong technical foundations and demonstrated execution speed in shipping. 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!

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

Required Experience

Engineering:

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

Design & Product:

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

Nice to have experience

Experience with game development

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

We look for candidates who

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

Here are some reasons to be a part of our team

Dive deep into the rapidly evolving world of AI and interactive learning.

Experience the joy of turning your designs and code into engaging and educational experiences for children worldwide

Be part of an A+ team and an engineering culture of excellence

About Ello

Ello is a public benefit corporation on a mission to maximize the potential of all children. We’re currently around 45 people, headquartered in San Francisco, with offices in São Paulo, Brazil; Nairobi, Kenya; and New York.

Our team has deep expertise in artificial intelligence, K-12 education, and child development across institutions such as Stanford, Berkeley, Google, Apple, and more. We were part of Y Combinator’s W20 batch and are funded by world-class investors including Goodwater Capital, Homebrew, Reed Hastings, Common Sense Growth, Ravensburger, Project A Ventures, Reach Capital, Khosla Ventures, WndrCo, Visible Ventures, and K9 Ventures.

We’re a small, collaborative team that takes each other’s voices very seriously. Because our mission is to support all children, it is critical that our team is representative of the communities we work in; we place significant emphasis on ensuring diversity in our team and inclusion in our culture.

We feel enormously privileged to be one of the few companies that has the opportunity to take a shot at truly revolutionizing education with AI at this inflection point in technology. We don’t take it for granted, so we work quite hard to turn that vision into reality with urgency. We want to create an environment in which we can all be our best selves, use our strengths to take Ello forward, and develop our own skills. We want to have fun while working hard to do impactful things that we’re proud of – and we believe it’s possible to do both.
