What does a successful Senior Android Engineer - Clover Sport do?

As a Senior Android Engineer for Clover Sport, you will own the development of high-volume, mission-critical point-of-sale software that powers concessions and retail for professional sports teams and venues nationwide. Operating in packed stadiums with unpredictable networks, you will ensure our applications remain fast, stable, and highly reliable under pressure. You will drive feature delivery from concept to launch across multiple POS applications and a shared library platform, balancing technical modernization with practical, business-driven decision-making while mentoring your peers.

What you will do:

• Design, build, and ship features across three POS applications and a shared ecosystem of supporting libraries and applications

• Work within a multi-module Gradle architecture, making sound decisions about where code belongs and how modules expose their APIs.

• Build robust order, payment, and fulfillment flows

• Integrate with the broader device and hardware ecosystem via AIDL, Content Observers, and Android Intents, plus specialized payment and receipt hardware (printers, scanners, kitchen display systems, etc...).

• Write new code in Kotlin, applying modern patterns while pragmatically maintaining and improving legacy Java.

• Contribute to UI using Conductor navigation, ViewBinding, and Epoxy, plus Jetpack Compose (Material 3).

• Write meaningful unit tests (JUnit, MockK, Robolectric) and instrumented/UI tests (Espresso, UiAutomator), and keep CI green.

• Participate in code reviews, uphold the team's code-style standards, and mentor mid-level engineers.

• Lead by example, treat everyone with respect, and prioritize quality above all else.

• Working directly with third-party vendors to define technical requirements and build integrations

What you will need to have:

• 5+ years of professional Android development, with significant Kotlin experience and comfort working in mixed Kotlin/Java codebases.

• Strong command of multi-module Gradle projects and dependency management at scale.

• Deep understanding of Android fundamentals: lifecycle, background work, IPC (AIDL, Intents, Content Observers), and threading/concurrency.

• Experience with networking (Ok Retrofit) and local persistence (Room / SQLite).

• A solid testing discipline across unit and instrumented tests.

• Proven ability to maintain and refactor large, long-lived production codebases without breaking things.

• Comfort working in a Git-flow branch/release model and CI/CD pipelines (GitHub Actions).

What would be great to have:

• Fintech, POS, payments, or hardware-integration experience (Clover SDK, card readers, receipt printers, barcode scanning).

• Jetpack Compose and modern UI architecture experience.

• Experience modernizing legacy code (e.g., RxJava ? coroutines, kapt ? KSP, migrating to Compose).

• Hands-on experience with dependency injection (Dagger 2) and reactive programming (RxJava); ability to reason about complex asynchronous flows.

• Experience leveraging AI-assisted development tools (e.g., GitHub Copilot, Google Gemini) to accelerate coding, debugging, code review, and test generation - while applying strong judgment to validate and refine AI-generated output.
