About The Position

The Senior Android Engineer is a leading velocity contributor for a cross-functional delivery Pod, responsible for shaping, reinforcing, and executing the technical direction of Android applications. They drive the design, implementation, and testing of high-quality, scalable mobile solutions, ensuring strong alignment with modern Android best practices and user experience standards. They play a critical role in accelerating team delivery by identifying and addressing technical and process bottlenecks, applying pragmatic engineering approaches, and maintaining a high bar for code quality, performance, and reliability. As a senior member of the team, they contribute meaningfully across the full mobile development lifecycle—from architecture and development through testing, release, and ongoing optimization. The Senior Android Engineer works closely with Product, Design, and cross-functional engineering partners to deliver user-centric solutions that meet both business and technical objectives. They bring a strong passion for the Android platform, championing technologies like Kotlin, Jetpack Compose, and Material Design, while staying current with evolving platform capabilities and industry trends. They also serve as a mentor and technical leader within the team, supporting the growth of junior engineers, promoting best practices, and contributing to a culture of continuous improvement, collaboration, and engineering excellence. This role follows a hybrid schedule and requires regular, in-person work at our Hampton, NH or future Boston, MA office. Our hybrid model is M/T/W in office and TH/F are optional work-from-home. Candidates must reside within commuting distance of either office. Fully remote work is not available for this role.
