[Hiring] Android Technical Lead @Accesa

Role Description

Our client is a leading technology provider in the retail industry, delivering modern point-of-sale and store operations solutions to retailers across multiple markets. As part of an ongoing platform modernization initiative, they are evolving their client architecture away from a legacy Java 8 Swing-based POS client toward a modular, offline-first, multi-platform model — supporting stationary POS terminals, self-checkout kiosks, and self-scanning devices across diverse retail environments.

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, owning the domain rules, use cases, and data flows for critical retail operations:

• Item registration
• Checkout
• Payment
• Customer management
• Promotion handling

Business continuity through offline operation, high testability, and performance under real retail conditions are non-negotiable priorities.

Qualifications

• 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).
• 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 capabilities.
• Senior stakeholder communication skills.
• 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.

Requirements

• Define clean repository, service, facade, DTO, and bridge contracts between Kotlin, platform-specific code, and the VueJS/TypeScript UI layer.
• Design, implement, and maintain shared KMP modules for POS business capabilities.
• Implement platform-specific code for desktop and Android targets using expect/actual patterns.
• Build offline-capable flows with local persistence, caching, synchronization readiness, and explicit failure handling.
• Write clean, well-structured code, participate in reviews, and improve existing modules through refactoring.
• Write automated tests for domain rules, use cases, repositories, bridge contracts, and coroutine-based flows.
• Work closely with frontend engineers, QA, product owners, and architects.
• Support teammates by sharing knowledge and mentoring less experienced Kotlin developers.
• Respect team agreements and processes, while providing regular updates on progress, trade-offs, and technical decisions.

Benefits

• Enjoy our holistic benefits program covering social, physical, emotional wellbeing, and work-life fusion.
• Physical Wellbeing: Medical benefits, gym support, and personalized fitness options.
• Work-Life Fusion: Flexibility to define the work-life dynamic that works for you.
• Emotional Wellbeing: Investment in mental wellbeing alongside physical health.
• Social Wellbeing: Connection through passions and interests in a hybrid environment.
