Job Title

Android AOSP Device Software Engineer

About your role

Clover, a Fiserv company, is a global leader in point-of-sale platforms powering millions of small businesses worldwide with integrated hardware, software, and payment solutions. The DeviceOS engineering team owns the core platform software running across all physical Clover smart devices and supports global mass manufacturing software pipelines. As a Staff AOSP Engineer based in Sunnyvale, CA, you will serve as the technical authority driving custom Android OS architecture, system framework modifications, low-level platform security, and factory provisioning to deliver a secure, high-performing device experience.

What you’ll do

Lead functional solution architecture, product requirements, and technical designs for custom Android Open Source Project (AOSP) builds across current and next-generation payment terminals.
Design, develop, and optimize Android system services, background daemons, and framework-layer components (frameworks/base/) compatible across multiple Android OS versions.
Bridge high-level application frameworks with low-level C/C++ native layers, working alongside Hardware Abstraction Layer (HAL) and kernel teams.
Partner directly with global manufacturing partners and test engineers to build, maintain, and optimize factory flashing tools, diagnostic software, and board bring-up daemons to achieve 100% manufacturing yield.
Architect platform security workflows, including PKI certificate provisioning, SELinux/SEAndroid policies, and HSM or ARM TrustZone integrations.
Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

Experience you’ll need to have

7+ years of hands-on software development experience with a primary focus on customizing, building, and deploying AOSP at the platform/OS layer.
Proven track record in the architecture, design, and customization of Android devices and platforms (frameworks/base, SystemServer, JNI, AIDL/HIDL) rather than consumer applications.
Technical proficiency in at least two major languages used in the AOSP stack: Java, C++, C, or Kotlin.
Hands-on experience adapting Android frameworks, system services, and Hardware Abstraction Layers (HAL).
Proficient with AOSP build tools and revision control workflows, including Git, Gerrit, repo, Android.bp, and Android.mk.
Deep understanding of platform security protocols, encryption/decryption, PKI certificate management, and Hardware Security Modules (HSM).

Experience that would be great to have

Hands-on experience with Android HAL development or Project Treble architecture.
Experience working directly with the Linux Kernel for Android, device drivers, or ARM TrustZone / TEE environments.
Demonstrated experience mentoring engineers, driving architecture reviews, and providing technical leadership to cross-functional teams.

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.

Benefits at Fiserv:

Fuel Your Life program to support your physical, financial, social, and emotional well-being
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
Eight Employee Resource Groups to foster a collaborative culture and expand your network
·Unparalleled professional growth with training, development, and internal mobility opportunities
Medical, dental, vision, life, and disability insurance options available from day one

Paid parental, caregiver, and military leave
