We’re growing fast and are excited to continue bringing world-class talent onboard to help shape the next chapter of our growth journey.

POSITION SUMMARY
 We’re looking for a Senior Android Engineer to join our Core UX Team, building high-quality mobile experiences that directly impact EarnIn’s customers. This role is ideal for someone with deep expertise in Android development, strong product intuition, and the ability to influence both technical and cross-functional decisions. As a senior engineer, you’ll own critical features end-to-end—from technical design and architecture through delivery, instrumentation, and long-term maintainability. You’ll collaborate with iOS and backend peers to drive cohesive experiences, mentor junior engineers, and help shape mobile best practices across the company.

We value engineers who bring system-level thinking, curiosity to learn from adjacent domains, and the drive to leverage new tools—including AI—to enhance velocity and quality. The base salary range for this full-time position is $207,000 - $253,000 plus equity and benefits. Our salary ranges are determined by role, level, and location. This is a hybrid position in Mountain View (Headquarters) and will require in-office work 2 days a week.

WHAT YOU'LL DO

  • Own the design, implementation, and delivery of complex Android features that serve as critical touchpoints in our customer journey.
  • Influence architecture and patterns across the mobile stack, driving best practices in scalability, modularization, accessibility, and performance.
  • Mentor and guide junior and mid-level Android engineers, raising the technical bar and fostering a culture of shared learning.
  • Partner closely with iOS, backend, design, and product leads to shape features, ensuring alignment across clients and services.
  • Write high-quality Kotlin code using Jetpack Compose, Coroutines, and modern Android architectures (MVVM/MVI/Clean Architecture).
  • Proactively identify and resolve technical debt, scalability risks, and opportunities for improving developer productivity.
  • Instrument and measure feature success, ensuring performance, accessibility, and analytics are part of the definition of done.
  • Collaborate with QA and product teams to ensure robust testing strategies (unit, UI, snapshot, and automation).
  • Champion the use of AI tools to enhance productivity, testing, and product innovation.

WHAT WE'RE LOOKING FOR 

  • Bachelor’s degree in Computer Science or related field, or equivalent practical experience.
  • 4+ years of professional Android development experience with Kotlin in production environments and Bachelor’s, or equivalent industry experience
  • Expertise in modern Android development, including Jetpack Compose, Coroutines/Flows, dependency injection (e.g., Hilt/Dagger), Android architecture components, and Gradle build optimization.
  • Proven experience in owning features end-to-end, from design/architecture through release and long-term maintenance.
  • Strong understanding of mobile UX principles, accessibility standards, and design system alignment.
  • Experience driving performance optimization, including profiling, memory management, and startup time improvements.
  • Demonstrated ability to collaborate in distributed, cross-functional teams, influencing product, design, and platform decisions.
  • Strong testing practices (unit, UI, integration, automated regression) and CI/CD familiarity.
  • Excellent written and verbal communication skills.
  • Experience with cross-platform mobile collaboration (iOS, React Native, Kotlin Multiplatform) is a plus. 
  • Familiarity with backend or API development (REST/gRPC/GraphQL) to enable more ownership is a plus.
  • Prior contributions to open source or mobile community knowledge sharing (talks, blogs, libraries) is a plus.
  • Proactive interest in working with AI-driven solutions, automation, or generative AI to improve mobile workflows and customer experiences is a plus.

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
