You will be rewarded for creativity and innovation. In this role, you will be joining a team responsible for developing next generation SDK's, tools, and apps that drive millions, and potentially billions, of payment transactions — including apps that integrate directly with payment terminal hardware and manage unattended, kiosk-mode Android devices in the field.

Essential Functions:

• Analyze, design, program, debug, and modify complex software enhancement features and/or new software products.
• Improving the performance of existing software.
• Debug and fix software including difficult issues using a broad knowledge of technologies.
• Participate in and influence project teams to create working software.
• Provide input and lead code reviews and technical meetings.
• Recommending new technologies that can help increase productivity.
• Contribute and influence project planning and estimates.
• Protect company proprietary and confidential information.
• Regularly attending team meetings to discuss projects, brainstorm ideas, and put forward solutions to any issues.
• Other duties as assigned.

Required Skills and Experience

• At least a BS/BA Degree in MIS, Computer Science, Engineering, or related field
• 6+ years of Android Experience, building applications or libraries
• 4+ years of Kotlin Experience
• Hands-on experience with Jetpack Compose (this is a Compose-first, XML/View-free environment)
• Candidate must have a commitment to industry best demonstrated practices, source code control, architecture, coding structure, and unit/system testing
• Strong object oriented programming experience
• Strong experience with Kotlin Coroutines and Flow for multithreaded and asynchronous programming
• Strong trouble-shooting and debugging skills
• Ability to design, plan, and implement features based on product requirements
• Experience with interfacing with RESTful services and consuming JSON or XML
• Familiarity with Source Control tools (Git)
• Experience working in large, multi-module Android projects (15+ modules) with dependency injection (Dagger/Hilt)
• Great English written and verbal communication skills
• Excellent multi-tasking skills, managing multiple initiatives at one time in a fast-paced environment

Desired Skills and Experience

• Experience with Material Design 3 or modern Android design systems — our CX application is actively migrating to M3 design guidelines
• Experience with Kotlin Multiplatform (KMP) development
• Experience in Unit Testing with Dependency Injection, including JUnit, Kotest, and MockK/Mockito
• Experience communicating with external devices over sockets or serial protocols (TCP/IP, USB, Bluetooth) — particularly integrating with POS/payment terminal hardware, printers, or similar embedded/peripheral devices
• Experience integrating multiple third-party or vendor SDKs behind a shared abstraction layer (e.g., supporting several hardware vendors from one codebase via product flavors)
• Experience with unattended or kiosk-mode Android device management (device admin, persistent launcher apps, remote provisioning)
• Experience with Agile/Scrum
• Experience creating and consuming AARs/JARs, including private Maven repositories (e.g., Artifactory/JFrog)
• Strong interest in the tooling/development process with continuous integration (Azure Pipelines, SonarQube, code coverage tooling)
• Proficiency with AI-assisted development tools (e.g., Claude Code, GitHub Copilot) to accelerate coding, debugging, code review, and test authoring
• Understanding of data security, encryption handling, PCI/EMV compliance, data privacy and related regulations
