Clover is a global leader in point-of-sale (POS) platforms, powering millions of small businesses worldwide with smart terminals and integrated payment solutions. We are looking for an Android Application Framework Developer - Device Engineering to join our Device Engineering team in Sunnyvale, CA. In this role, you won't just be building standard mobile screens-you will bridge the gap between high-level Android services and physical hardware peripherals (thermal printers, barcode scanners, cash drawers, scales, and payment modules). If you are a recent graduate or early-career engineer eager to dive deep into the Android OS, manage USB/network hardware protocols, and see your code drive physical smart terminal hardware used by millions of merchants daily, this is the team for you. What You Will Do * Hardware-Connected Android Services: Develop Android application framework services and background daemons in Kotlin and Java that interface directly with external hardware and microcontrollers. * Peripheral SDK & Hardware Integration: Integrate third-party vendor SDKs and write communication pipelines for POS peripherals, including receipt printers, barcode scanners, cash drawers, and weight scales. * USB & Network Protocol Management: Utilize Android USB Host (OTG) APIs to manage hardware attach/detach lifecycle events, configure dynamic USB permissions, and implement socket programming for network IP printers. * System & Device Troubleshooting: Use command-line tools (adb, Logcat, packet/serial sniffers) to isolate, reproduce, and debug hardware integration bugs and OS regressions across our terminal fleet. * AOSP & Platform Exposure: Collaborate with senior engineers to explore Android Open Source Project (AOSP) internals, framework extensions, and custom device services. * AI-Assisted Engineering: Leverage modern AI-assisted engineering tools (such as GitHub Copilot, Claude Code, and coding agents) to accelerate development, refactor framework code, and optimize debugging workflows., * Familiarity with the Android USB Host API (android.hardware.usb) or managing hardware permissions and USB intent filters. * Coursework or project exposure to the Android Open Source Project (AOSP) or building custom Android ROMs/firmware. * Hands-on experience integrating third-party vendor hardware SDKs or libraries. * Exposure to low-level microcontroller communication (SPI, I2C, UART) or embedded Linux environments. How you'll work: * This role is on-site Monday through Friday. Fiserv considers in-person collaboration to be an essential part of this role as in-person office experiences help you with your overall onboarding experience and leads to stronger productivity. * This role requires use of a computer and audio equipment., If you have a disability and require a reasonable accommodation in completing a job application or otherwise participating in the overall hiring process, please contact AskHR.US@fiserv.com .
