Android Technical Lead

Full-time

Department: Core Technologies | Frontend 2

About the Position

We are seeking an experienced Android Technical Lead to join our client, a leading technology provider in the retail industry. This role is pivotal in modernizing their retail POS architecture by evolving it from a legacy Java 8 Swing-based POS client to a modular, offline-first, multi-platform model. The shared business logic layer is built with Kotlin Multiplatform (KMP), targeting both JVM/Desktop and Android clients. This layer is the heart of the platform, managing domain rules, use cases, and data flows for critical retail operations.

Responsibilities

• Architecture ownership: Define clean repository, service, facade, DTO, and bridge contracts between Kotlin, platform-specific code, and the VueJS/TypeScript UI layer.
• Technical delivery: Design, implement, and maintain shared KMP modules for POS business capabilities, ensuring high-quality, maintainable, and performant code across JVM/Desktop and Android targets.
• Platform integration: Implement platform-specific code for desktop and Android targets using expect/actual patterns, without leaking platform concerns into shared business logic.
• Offline-first delivery: Build offline-capable flows with local persistence, caching, synchronization readiness, and explicit failure handling.
• Code quality: Write clean, well-structured code, participate in reviews, and improve existing modules through refactoring where needed.
• Testing: Write automated tests for domain rules, use cases, repositories, bridge contracts, and coroutine-based flows.
• Collaboration: Work closely with frontend engineers, QA, product owners, and architects to align on contracts, requirements, and feature delivery.
• Knowledge sharing: Support teammates by sharing knowledge and mentoring less experienced Kotlin developers when appropriate.
• Team alignment: Respect team agreements and processes, while providing regular updates on progress, trade-offs, and technical decisions.

Requirements

Must Have

• 8+ years of experience with Kotlin, including architecture decision making with KMP at platform scale
• Strong system-level Android experience
• Strong hands-on KMP delivery to at least two targets (preferably Android and JVM/Desktop) and KMP-Swift/iOS interoperability knowledge
• Java-to-Kotlin/KMP migration at platform scale
• Architectural leadership and vision
• Modular product architecture with customer-specific extension points
• Knowledge transfer and mentoring
• Senior stakeholder communication
• Solid understanding of Clean Architecture
• Practical experience with Kotlin Coroutines and Flow
• Experience with offline-first or local-first client architecture
• Familiarity with dependency injection patterns, preferably Koin
• Strong testing discipline
• Experience integrating REST/OpenAPI-style services
• Comfortable with Gradle Kotlin DSL, modular builds, and CI-friendly project structures
• Effective communication skills for collaboration with frontend developers, QA, and product stakeholders

Nice to Have

• Compose Multiplatform experience
• POS / retail embedded systems experience
• Desktop JVM client experience, especially Electron sidecar or local service integration patterns
• Understanding of VueJS 3 and TypeScript
• Experience with plugin or extensibility architecture
• Performance engineering experience for latency-sensitive client operations
• POS, retail, payment, promotion, or hardware peripheral integration experience
