## Description

## Job Summary

We are seeking a Senior Mobile Engineer (Android) to join our Growth Engineering team at EarnIn. As a Senior Mobile Engineer, you will play a key role in accelerating customer acquisition, activation, engagement, and retention by working on high-impact web and mobile projects.

## Responsibilities

- Partner with product, design, and analytics teams to define and solve problems, including writing specifications and implementing solutions.

- Build and refine systems that drive acquisition, activation, engagement, and retention, deciding what to test, when to ship, and how to measure results.

- Work across multiple stacks as needed, owning Android but contributing to iOS, backend, or web (React/TypeScript) when necessary.

- Utilize AI-native development workflows, including AI coding tools and agents for cross-stack code generation, spec-driven development, and faster iteration.

- Translate customer pain points and business goals into technical solutions, pushing back when data suggests a better approach.

- Run and instrument experiments to validate that shipped features move growth metrics, and eliminate ineffective solutions.

- Develop scalable architecture that enables the organization to remain agile as it expands.

- Drive decisions on app development and testing strategies and methodologies.

- Ship iteratively, prioritizing ruthlessly, scoping MVPs, and balancing speed against quality.

- Create unit and automation tests to ensure new code doesn't break existing features and meets product requirements.

- Own projects end-to-end, from specification through launch and iteration, with minimal oversight.

## Requirements

- Bachelor's degree in Computer Science or a related technical field, or equivalent technical experience.

- 4+ years of industry experience building, shipping, and maintaining mobile applications at scale, with a strong focus on Android.

- Strong ownership and willingness to work across stacks, with a growth mindset and comfort with ambiguity.

- Fluency in Kotlin, with a strong grasp of reactive and functional paradigms.

- Proven experience with modern Android app architectures and Jetpack components.

- Deep understanding of Android UI frameworks, including XML layouts and Jetpack Compose.

- Hands-on knowledge of software engineering best practices across the full SDLC.

- Experience using AI-assisted development tools is a plus.

- Experience with mobile analytics and experimentation tooling is a strong plus.

- Familiarity with iOS development, backend development, or web (React/TypeScript) is a significant plus.

## Benefits

- Excellent benefits, including healthcare, internet and cell phone reimbursement, a learning and development stipend, and potential opportunities to travel to our Mountain View, CA headquarters.
