Working across the full development lifecycle, you will collaborate closely with product, design, and backend teams to deliver reliable, high-performance features. The environment is highly ownership-driven, where engineers influence architecture, coding standards, and product direction. You will be solving complex challenges involving payments, offline resilience, and hardware-adjacent systems. This is a hands-on engineering role where your work is deployed into production stores and used daily by frontline retail teams.

Responsibilities

• Design, develop, and deliver robust point-of-sale features using Kotlin for Android-based terminal applications.
• Own the full software lifecycle including architecture, development, testing, deployment, and ongoing optimization.
• Collaborate with cross-functional teams to translate business requirements into scalable technical solutions.
• Improve application performance, responsiveness, reliability, and user experience across devices and environments.
• Conduct code reviews and enforce engineering best practices, secure coding standards, and maintainable architecture.
• Work on payment-related workflows, hardware integrations, and offline-first capabilities where applicable.
• Stay up to date with Android ecosystem advancements and contribute to continuous engineering improvements.

Requirements

• 5+ years of professional Android development experience with strong proficiency in Kotlin.
• Deep understanding of the Android SDK, Android Studio, and modern application architecture patterns.
• Experience integrating with RESTful APIs and working with JSON and other data formats.
• Strong knowledge of version control systems, particularly Git.
• Solid understanding of Android UI/UX principles, performance optimization, and secure coding practices.
• Excellent debugging, problem-solving, and communication skills in collaborative engineering environments.
• Familiarity with AI tools for engineering productivity, with awareness of appropriate usage contexts.

Nice to have

• Experience with POS systems, payment processing, or retail technology environments.
• Experience with Jetpack components (Compose, ViewModel, WorkManager, Room, etc.), reactive programming (Flow/Rx), dependency injection, and CI/CD pipelines.

Benefits

• Competitive base salary range of $160,000-$180,000 depending on experience and qualifications.
• Equity package with long-term growth potential.
• Comprehensive medical, dental, and vision insurance.
• Unlimited flexible paid time off.
• Opportunity to work on real-world POS systems used in production retail environments.
• High ownership role with influence over architecture and engineering standards.
• Exposure to fast-growing, high-scale retail and payments technology.
• AI-forward engineering culture that encourages modern development workflows.
