Staff Software Engineer, Android

About The Team
The Core Services Team builds and maintains the mission-critical, high-throughput, and fault-tolerant foundational services that power the entire platform. This includes services for safety, identity, payments, and other core business logic.

As a Staff Software Engineer (Android), you will be a technical leader who operates with a broad scope, influencing the technical direction not just within your team but across multiple dependent mobile teams. You will drive the design and implementation of highly scalable, reliable, and performant client-side architecture for foundational platform components, setting a high bar for engineering excellence and mentoring senior engineers.

What You'll Do
Technical Leadership & Architecture (Mobile)

• Lead the design and architecture of large-scale, resilient Android platform components and libraries for core services (e.g., ensuring high performance, low latency, and a consistent, multi-platform user experience).
• Own complex mobile technical initiatives that impact major product areas or multiple Android and cross-platform engineering teams.
• Drive technical decision-making and establish architectural standards and patterns for the wider Core Services mobile organization, focusing on modularity, testability, and maintainability.

System Implementation & Operational Excellence

• Implement critical, high-performance Android features and modules using modern mobile frameworks (e.g., Kotlin, Jetpack Compose, or equivalent), ensuring they are scalable, secure, and maintainable.
• Champion a culture of operational excellence by establishing best practices for mobile crash/error monitoring, performance profiling, and proactive client-side health improvements.
• Aggressively identify and resolve mobile technical debt, architectural deficiencies, and non-performant UI/logic across related client systems.

Cross-Organizational Influence

• Partner closely with Staff Engineers, Engineering Managers, and Product Managers to define technical roadmaps that align with long-term business strategy, specifically for how core services are consumed and utilized on the mobile platform.
• Represent the team and its technical strategy in cross-organizational forums and drive consensus on complex technical tradeoffs between mobile, backend, and cross-platform concerns.

Mentorship & Development

• Act as a force multiplier by mentoring other Android engineers, elevating the technical capabilities of the entire team.
• Provide in-depth, thoughtful feedback in design and code reviews for critical mobile systems, emphasizing Android best practices, performance, and memory management.
• Contribute to the engineering culture by championing best practices in testing, deployment, and security within the mobile CI/CD pipeline.

Minimum Qualifications

• 12+ years of professional experience as a Software Engineer, with significant experience in designing, building, and operating large-scale, high-availability Android applications or platform libraries in a production environment.
• Deep expertise in Android/Mobile Infrastructure (e.g., modern Android architecture, dependency injection, threading, lifecycle management, performance optimization).
• Proven ability to lead projects, break down ambiguous technical problems, and drive complex, multi-quarter initiatives to successful completion.
• Strong understanding of mobile operating system internals, best practices for battery/data usage, and security considerations on the Android platform.

Preferred Qualifications

• Master's degree in Computer Science, Software Engineering, or related technical field.
• Experience with site reliability engineering (SRE) principles as they apply to mobile applications (e.g., client-side telemetry, proactive rollout strategies).
• A track record of influencing mobile engineering strategy and architecture across different organizational boundaries.
