As the lead game engineer, you’ll spearhead Ello’s transition from reactive app development to character-imperative game development in Unity: You’ll build our game development team with us and make key architectural decisions.

You’re responsible for bringing Ello’s tutoring AI to life. You’re passionate about character development and game interactions. You want to build products that delight users. You see how small changes in the facial expressions of a character or the shading of the background affect the emotional impact of the things you create. You have experience working with 2D animation in Unity. You know how to structure a project well and love setting up infrastructure from scratch.

You thrive working in a fast-paced early-stage environment. You enjoy teaching other developers that are just getting started with Unity and value mentorship. You’ll eagerly show us the tricks of your favorite IDE and the intricacies of your workflow. You’ll lead the way both as an architect and by setting an example as an individual contributor who writes great C# code.

Most importantly, you are excited about the opportunity of making an impact on child development at scale.

Required Experience

• A track record of shipping 2D games on mobile platforms

• Understanding the performance implications of your code at a systems level

• Experience writing high-performance, parallelized code
• Strong ability to read React/React Native code, perhaps through prior experience working on a JavaScript frontend project
• Basic design skills; some experience using basic design tools to convey your ideas and make small asset adjustments (Figma, Photoshop, some animation tool)
• Experience with product analytics from query to visualization

What You’ll Be Building

Reading is the gateway to learning but unfortunately, many children do not receive the individualized support they need to become confident, capable and engaged readers. This creates a cycle where they find reading frustrating and, by avoiding it, fall further behind. Parents want to take action, but they don’t have the experience or time. Enter Ello, an expert coach that makes reading fun and breaks this cycle.

Our first product is an AI reading coach that listens to a child read from real books. It uses evidence-based reading instruction to help them when they get stuck and behavioral psychology to motivate them to keep going.

Who You’ll Be Joining

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 wider community; we place significant emphasis on ensuring diversity in our team and building an inclusive culture.

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 – we believe it’s possible to do both.
