Ello
Engineering, full-time
San Francisco (Relocation assistance available)
Salary range: $140,000 - $210,000 + Equity
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. 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 Design Engineer to bridge the gap between design and engineering, focusing on creating seamless front-end experiences on mobile platforms. You will own feature development from start to finish, at times acting as your own product manager, and collaborating closely with product and engineering teams. You don’t need to be an illustrator, but you’re able to take an existing component library and build new frontend tools from scratch on the frontend (React & Flutter) without a designer. You’re responsible for bringing Ello’s tutoring AI to life through character development and game interactions. You pay attention to the details. You want to build products that delight users.
We welcome candidates from both design and engineering backgrounds, but we prioritize strong technical foundations and demonstrated execution speed.
Responsibilities
Develop and integrate front-end components for mobile and web platforms, leveraging existing design systems and brand guidelines
Own features end-to-end, from concept to delivery
Serve as a bridge between design and engineering, moving fluidly between UX/UI and technical problem-solving
Build new components and maintain consistency within the app
Set up basic infrastructure, manage production workflows, and handle continuous integration and app store delivery/release processes
Required Experience
-
Design:
Proven UI/UX design skills, with experience across both mobile and web interfaces
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 ability to work within existing design systems and brand standards to build new front-end components
Cross-functional skills, having either picked up engineering from a design domain or design skills from a computer science background
-
Engineering:
Experience with object-oriented programming and production-grade mobile development
Computer science/engineering background or equivalent extensive front-end engineering experience
Knowledge of front-end development platforms (web and mobile)
Understanding of mobile app architecture, design patterns, and performance optimization techniques
Experience with Flutter or native Android development in Java/Kotlin
Familiarity with Git flow, basic infrastructure setup, and production workflows
Exposure to continuous integration, app store delivery, and release processes
Exposure to agile development methodologies and project management tools, version control systems, and collaborative development tools
Nice to have experience
Experience as a product manager or in a role with significant ownership over features or components.
Experience with game development
Experience with generative AI applications
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
Immerse yourself in a collaborative environment surrounded by an A+ team
Dive deep into the rapidly evolving world AI and interactive learning.
