Job Title

Android Application Framework Developer - Device Engineering

About Your Role

Kickstart your engineering career at the intersection of Android software and physical hardware! 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.

What You Need to Have

Education: Bachelor’s or Master’s degree in Computer Engineering, Electrical & Computer Engineering (ECE), Computer Science, or a related discipline (Graduating seniors or recent grads welcome).
Hardware/Device Project Experience: Demonstrated classroom, capstone, research lab, or personal project experience building software that talks to physical devices or external hardware (e.g., IoT devices, Arduino/Raspberry Pi, robotics, microcontrollers, USB accessories, or sensor integration).
Core Languages: Strong foundational coding skills in Java or Kotlin , with working knowledge or academic exposure to C or C++ .
Android Fundamentals: Practical understanding of native Android development fundamentals (Activities, Services, BroadcastReceivers, Intents, and background threading).
Networking & Hardware Protocols: Academic or practical familiarity with low-level communication concepts such as TCP/UDP socket programming, USB device communication (Host/OTG), or serial/UART protocols .
CS & Systems Foundations: Rock-solid grasp of core computer science fundamentals: Object-Oriented Design, Data Structures, Operating Systems (threading, processes, memory management), and Git version control.
Eagerness to Learn: High curiosity, passion for device hardware, and excitement to learn POS platform architecture and payment security standards.

Experience that would be great to have:

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.

Individuals with temporary visas including, but not limited to, F-1 (OPT, CPT, STEM), H-1B, H-2, or TN, or any candidate requiring sponsorship, now or in the future, will not be considered for this role.

Benefits at Fiserv:

Paid holidays and generous time away policies
No-cost mental health support through Employee Assistance Programs
Living Proof program to recognize your peers’ extra effort with points redeemable for rewards
