Senior Android Engineer, Product Engineering

Overview 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 optimisation. 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. Responsibilities Technical Contributions Actively contributes to the design, implementation, and testing of Android applications using Kotlin, Jetpack Compose and modern architecture patterns (MVVM, MVI, Clean Architecture). Identifies and removes delivery and quality bottlenecks (e.g., build performance, app performance, release friction) through pragmatic, scalable solutions. Applies modern Android practices, including CI/CD, automated testing (unit and UI), observability and performance monitoring. Champions Android platform excellence, including Material Design, accessibility, responsiveness and device compatibility. Contributes to the Android technical vision and helps evolve mobile architecture and standards. Leverages AI‑powered tools to improve development efficiency and shares learnings with the team. Acts as a trusted advisor on Android‑specific design, architecture and platform capabilities. Champions best practices (lifecycle management, state handling, performance optimisation, modularisation) through code reviews and mentorship. Cross Functional Collaboration Executes delivery plans using modern Android technologies to build performant, user‑centric mobile experiences. Proactively identifies and mitigates risks related to performance, device fragmentation and platform constraints. Collaborates closely with Product and Design to deliver intuitive, high‑quality experiences aligned with Material Design principles. Partners with backend and platform teams to ensure seamless integration and efficient, reliable releases (including Play Store rollout strategies). High Quality Development and Delivery Ensures quality through strong testing practices, monitoring and iterative release cycles. Team and Culture Building Supports and mentors junior engineers, strengthening team capabilities in Kotlin, Compose and modern Android development. Contributes to a high‑performance, inclusive engineering culture grounded in trust, accountability and collaboration. Advocates for mobile excellence across performance, usability, accessibility and platform consistency. Promotes continuous learning, experimentation and adoption of modern Android tools and practices. Leads by example with strong ownership, craftsmanship and pride in delivering high‑quality mobile experiences. A deep passion for the platform and helping improve the lives of millions of people.
