Senior Android Developer (Kotlin & Platform Internals)

Company Description

ppltx is a tech-driven mobile apps publisher specializing in hyper-casual games and

utility apps and we're looking for a Senior Android Developer to join our R&D team and take a

key role in building and scaling our Android native apps & SDKs, powering user experience,

monetization flows, and live operations.

This role is designed for an engineer who is deeply fluent in Kotlin, not just as a language, but

as a platform and who has ventured beyond the standard SDK surface into the Android Open

Source Project (AOSP) to understand how the OS itself works.

This is also a unique opportunity for a developer who embraces AI as a core part of their

workflow: someone who uses it not just as a tool, but as a force multiplier to ship faster, think

bigger, and build smarter.

What you’ll do

• Design, build, and maintain Android native applications in Kotlin, leveraging AI coding tools (e.g. Cursor, Claude) to accelerate development cycles and reduce repetitive overhead.
• Own end-to-end delivery: architecture, implementation, performance, stability, and release readiness, using AI-assisted workflows to move with speed and confidence.
• Integrate and maintain mobile SDKs (ads/mediation, analytics, attribution, remote config, etc.), utilizing AI tools to streamline integration, documentation, and debugging.
• Collaborate closely with backend, product, QA, and data teams to deliver high-impact features, using AI to prototype faster and communicate technical decisions more clearly.
• Improve engineering standards across automation, CI/CD, testing, and monitoring, including exploring how AI can enhance test generation, code review, and anomaly detection.

Requirements

• Strong mobile development experience in production environments.
• 5+ years of experience with Kotlin and Android Studio.
• Active, hands-on use of AI development tools (Cursor, Claude, Gemini, or similar) as a meaningful part of your daily workflow, not occasional experimentation.
• Deep understanding of Android fundamentals: lifecycle, threading/coroutines, networking, storage, background execution.
• Experience shipping apps at scale, including performance optimization and stability improvements.
• Familiarity with modern Android architecture patterns (MVVM/Clean), modularization, and dependency injection.
• Strong analytical thinking and problem-solving skills; ability to break down complex systems.
• Strong communication and collaboration skills; able to influence technical direction.
• Self-motivated, adaptable, and genuinely excited about how AI is reshaping software development.

Advantage

• Demonstrated ability to use AI tools to accelerate delivery, faster prototyping, AI-generated tests, AI-assisted code reviews, or prompt-driven debugging workflows.
• Experience with Gradle, CI/CD for Android, unit/integration/UI testing.
• Experience integrating ad SDKs/mediation, analytics/event systems, and attribution.
• Experience with build variants/flavors, proguard/r8, Play Console releases, and app signing.
• Familiarity with networking stacks (Retrofit/OkHttp), Jetpack libraries, Compose, Firebase, and crash reporting tools.

What we offer

• A culture that actively embraces AI tools and encourages engineers to constantly evolve how they work.
• Challenging work in a rapidly evolving domain (mobile gaming + monetization).
• Real ownership and impact on architecture and product outcomes.
• Room to learn, grow, and advance as the company and the technology scales.

If you're an Android developer who has already made AI a core part of how you build, and

you're excited about high-quality apps that drive monetization and growth at scale, we'd love to

hear from you.
