Job description

About the Role

We're a product-focused fintech startup building a consumer mobile app that helps everyday users manage money more easily — think cash advances, early wage access, and credit building, all without interest or hard credit pulls. Founded in 2020 and backed by Series A funding, our small but mighty team (11–50 people) operates out of San Francisco.

We're looking for a Senior Android Software Engineer to take meaningful ownership of our core Android application. You'll work closely with product, engineering, and business leaders to craft polished consumer experiences and drive measurable impact on user happiness and growth.

What You'll Do

  • Design, implement, and maintain a high-quality consumer-facing Android app

  • Help build and evolve the mobile platform layer shared across the engineering team

  • Pragmatically solve complex technical and product problems at pace

  • Contribute meaningfully to product design decisions and technical direction

  • Collaborate cross-functionally with product, engineering, and business stakeholders

  • Mentor and provide technical guidance to junior engineers on the Android team

What We're Looking For

Required

  • 2+ years of mobile engineering experience, with shipped consumer-facing apps (not solely B2B)

  • Strong Kotlin expertise for Android, including Jetpack Compose and modern app architecture (MVVM / Clean Architecture)

  • Experience with backend data formats and APIs common in mobile: protobufs, REST, and gRPC

  • Hands-on experience integrating Firebase services (Authentication, Firestore/Realtime Database, Cloud Messaging)

  • Proficiency with Android testing strategies (unit tests, instrumentation/UI tests) and maintaining CI/CD pipelines for mobile

  • Clear, effective communication and a proven ability to collaborate across functions

Nice to Have

  • Mentorship or technical leadership experience guiding junior mobile engineers

  • Familiarity with Dagger Hilt dependency injection

  • Exposure to Go, GCP, BigQuery, or MySQL on the backend

Note: Visa sponsorship is available for this role.

Compensation & Benefits

  • Salary: $160,000 – $200,000 USD annually

  • Competitive equity in a well-funded, early-stage fintech company
