Senior AOSP Engineer

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

• Digging into the Android Open Source Project (AOSP), the Linux Kernel, and low-level APIs to dial in great custom hardware experiences and features.
• 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.
• 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).

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. Through a singular focus on care for our customers, Skylight has scaled from a school project to over $180M in annual revenue while being completely bootstrapped. We have a huge opportunity to make family life easier and more connected, and that’s why we have been working hard to expand our team.

At Skylight, our engineering team is small but mighty — our software powers an experience for millions of customers.

• Develop and debug the Linux kernel and device drivers for our custom hardware.
• Perform low-level device debugging (e.g., using UART, JTAG).
• Implement and maintain robust OTA (Over-the-Air) system image update workflows.
• Conduct system performance profiling and optimization (e.g., using systrace, perfetto) across the entire software stack, from kernel to SDKs.
• Collaborate closely with product management, hardware, and other engineering teams on technical requirements and seamless hardware/software integration.
• Create and maintain detailed documentation related to AOSP and low-level system development.
• Assist in project management for AOSP development, ensuring timely delivery.
• Provide technical support for system-level and AOSP-related issues internally and externally.
• Stay updated with the latest trends and best practices in AOSP and Android platform engineering.
• Communicate regularly and clearly with stakeholders about progress and challenges.
