Senior Android Software Engineer - SDK, API, and OTA

This might be the perfect role for you if you are excited by:

• Working on Android software that is shipped directly to our custom hardware rather than a typical mobile application
• Digging into APIs and SDKs close to AOSP and firmware while keeping your responsibilities in the application layer (it’s a great chance to expand your knowledge and learn new things!)
• Being one of the first people to get access to early prototypes and test units of new hardware
• Having input on the CPU, memory, and other specs that will be included
• Contributing to the development and roadmap for a major piece of our tech stack (our in-house OTA utility)
• Driving much of your own roadmap (TONS of autonomy)
• Building a product that our customers genuinely love because it solves real, everyday problems for busy families and those with neurodivergent kids (the ADHD and Autism communities are among our biggest fans)

If so, read on!

Skylight’s mission is to build the OS of the family. We make consumer products, like Skylight Frame and Skylight Calendar, that are loved by millions of people across the globe.

We've built a healthy, bootstrapped, and profitable business, and are scaling our Engineering team to better support our growth, improve our technical infrastructure, and continue to expand the feature set for customers.

This is a Senior or higher-level position.

Our ideal candidate is a deeply experienced Android engineer with expert-level command of Android App development, Kotlin, and Clean architecture (MVVM). But more than that, they’re experienced in working on low-level APIs, navigating AOSP, and implementing Android solutions for custom hardware. Experience working with Jetpack Compose is nice to have, but not required.
