Incard’s mission is to build the financial operating system for entrepreneurs.
We are focused on creating a system where business banking, financial tools, and application logic are coordinated into a single control layer.
Through the app store, entrepreneurs and developers can build industry-specific functionality as their business evolves.
Our team is small, highly motivated, and focused on engineering excellence. We operate with a flat organizational structure. All employees are expected to be hands-on and to contribute directly to the company’s mission. Leadership is given to those who show initiative and consistently deliver excellence. All engineers are expected to have strong communication skills. They should be able to concisely and accurately share knowledge with their teammates.
We’re looking for a Senior Android Engineer who cares deeply about architecture, performance, and product quality and who enjoys building scalable, well-crafted mobile experiences in a complex domain.
You’ll collaborate closely with Android, iOS, Backend, and Product teams to build and evolve Incard’s Android app, used daily by modern e-commerce businesses to manage spending, cards, and financial insights.
This role is ideal for someone who thrives in fast-moving environments, takes ownership beyond tickets, and brings strong product thinking alongside technical excellence.
Build, scale, and maintain Incard’s Android application using Kotlin and Jetpack Compose
Design and evolve scalable Android architecture beyond MVP, using clean, modular patterns
Collaborate closely with Product, Backend, Android and iOS teams to deliver high-quality features

Product-minded engineer with strong attention to detail and edge cases
Comfortable using AI tools (e.g. Cursor, modern LLMs) to accelerate development responsibly
Strong communication skills, open to feedback and continuous improvement
