Sr. Android Engineer

About the role

Clover is a pioneer in the fintech space, dedicated to transforming the way small and medium-sized businesses operate. As a part of Fiserv, we provide an all-in-one point-of-sale (POS) and business management platform that handles everything from seamless payment processing to inventory and staff management. With over 15 billion transactions processed annually, Clover empowers merchants worldwide to run their businesses more efficiently and grow with confidence.

Responsibilities

• Design, build, and ship features across three POS applications and a shared ecosystem of supporting libraries and applications
• Work within a multi-module Gradle architecture, making sound decisions about where code belongs and how modules expose their APIs
• Build robust order, payment, and fulfillment flows
• Integrate with the broader device and hardware ecosystem via AIDL, Content Observers, and Android Intents, plus specialized payment and receipt hardware (printers, scanners, kitchen display systems, etc...)
• Write new code in Kotlin, applying modern patterns while pragmatically maintaining and improving legacy Java
• Contribute to UI using Conductor navigation, ViewBinding, and Epoxy, plus Jetpack Compose (Material 3)
• Write meaningful unit tests (JUnit, MockK, Robolectric) and instrumented/UI tests (Espresso, UiAutomator), and keep CI green
• Participate in code reviews, uphold the team's code-style standards, and mentor mid-level engineers
• Lead by example, treat everyone with respect, and prioritize quality above all else
• Work directly with third-party vendors to define technical requirements and build integrations

Requirements

• 5+ years of professional Android development, with significant Kotlin experience and comfort working in mixed Kotlin/Java codebases
• Strong command of multi-module Gradle projects and dependency management at scale
• Deep understanding of Android fundamentals: lifecycle, background work, IPC (AIDL, Intents, Content Observers), and threading/concurrency
• Experience with networking (OkHttp, Retrofit) and local persistence (Room / SQLite)
• A solid testing discipline across unit and instrumented tests
• Proven ability to maintain and refactor large, long-lived production codebases without breaking things
• Comfort working in a Git-flow branch/release model and CI/CD pipelines (GitHub Actions)

Qualifications

• Fintech, POS, payments, or hardware-integration experience (Clover SDK, card readers, receipt printers, barcode scanning)
• Jetpack Compose and modern UI architecture experience
• Experience modernizing legacy code (e.g., RxJava → coroutines, kapt → KSP, migrating to Compose)
• Experience leveraging AI-assisted development tools (e.g., GitHub Copilot, Google Gemini) to accelerate coding, debugging, code review, and test generation — while applying strong judgment to validate and refine AI-generated output
