About your role:

You will join the Clover Device Engineering team, which is responsible for the core software and operations of Clover’s Android-based payment terminals. Clover delivers an elegant end-to-end Point of Sale system, powering millions of daily transactions for merchants globally. In this role, you will be an Android Application and Back-End Engineer, driving the development, certification, and operation of critical terminal features that connect our devices to the cloud.

What you’ll do:

• Core Systems Design: Designing and implementing complex solutions that span across Android applications, secure Inter-CPU communication, the Real-Time Operating System (RTOS), and payment kernels.
• Feature Integration: Adding critical payment features (such as dynamic currency conversion, mobile wallets, and offline payment support) to our existing products.
• Component Ownership: Taking end-to-end technical ownership of specific, mission-critical payment components on the terminal.
• Deep Troubleshooting: Troubleshooting and resolving highly complex issues that span the full device stack, from the Android application layer down to the embedded hardware/RTOS.
• Compliance & Certification: Working closely with international certification teams (e.g., EMVCo) and test organizations to ensure compliance and readiness.
• Collaboration: Working with Product Management to clarify and/or create technical specifications.
• Support: Triaging bugs related to payment applications and related infrastructure, and performing production support services as part of a regular on-call rotation.
• Responsibilities listed are not intended to be all-inclusive and may be modified as necessary.

Experience you’ll need to have:

• 5+ years of software development experience.
• Must have demonstrable experience in the architecture and design of Android devices and embedded platforms.
• Proficiency in at least two major programming languages, with a focus on C/C++ for low-level tasks and Java/Kotlin for the Android application layer.
• Strong Android app development experience using Kotlin and native code (JNI).
• Experience with UI development, optimal performance, and adaptation to various screen sizes.
• Good working knowledge of revision control and code review tools like Git, Gerrit, etc.
• General understanding of security protocols, encryption/decryption technologies, PKI, HSM, and certificate management.

Experience that would be great to have:

• Embedded/MCU/ARM Cortex development, RTOS, and C language experience.
• Previous experience in the payments industry, specifically working with EMVCo or exposure to PCI/PTS standards would be very helpful but is not required.
• Back-End development with Spring Boot.

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 being on-call during non-standard and/or overnight hours on a rotational basis.
