Job description

• We are seeking a Senior Android Developer to build and evolve high-quality native Android applications. You will take features from concept to release, combining strong hands-on engineering in Kotlin and Core Java with a proactive, ownership-driven approach.
• This role suits an engineer who takes pride in craftsmanship — someone who owns their work end-to-end, anticipates problems before they surface, and drives tasks to completion with minimal supervision.

Key Responsibilities

• Design, develop, and maintain native Android applications with a focus on performance, stability, and user experience.
• Own assigned features and tasks end-to-end — from technical design through development, testing, and release.
• Write clean, maintainable, well-tested code in Kotlin and Core Java.
• Collaborate with product, design, backend, and QA teams to deliver features on schedule.
• Diagnose and resolve defects and production issues across the app stack.
• Uphold engineering quality through code reviews, testing, and adherence to Android best practices.
• Languages: Kotlin, Core Java
• Native Android: Android SDK, Jetpack components (ViewModel, Lifecycle, Room, Navigation), Jetpack Compose and/or XML layouts
• Architecture & tooling: MVVM / Clean Architecture, dependency injection (Hilt/Dagger), Android Studio, Gradle, Git
• Integration: REST APIs (Retrofit/OkHttp), push notifications, Play Store release workflows

Required Skills & Experience

• 5–10 years of professional software engineering experience, with a strong focus on native Android development.
• Proven, verifiable results delivering Android applications to production — e.g., shipped apps, measurable performance or quality improvements.
• Strong programming skills in Kotlin and Core Java.
• Deep understanding of the Android SDK, application lifecycle, memory management, and performance optimization.
• Experience with modern Android architecture patterns (MVVM, Jetpack) and automated testing (JUnit, Espresso).
• Experience building and/or leveraging AI agents (e.g., agentic workflows, LLM-based automation, AI-assisted engineering tools) to improve productivity and outcomes.
• Ability to work onsite in San Diego, CA.

What We Look For

• Strong sense of ownership — takes end-to-end responsibility for outcomes, not just tasks.
• Self-motivated and proactive; able to operate independently with minimal supervision.
• A good team player who collaborates effectively across teams, geographies, and time zones.
• Proven track record of delivering measurable results in previous roles.
