Android Engineer​/Finance​/Crypto apps

The Role

You will serve as a key contributor to the development of our flagship Android client. A significant part of this role involves working closely with product managers, designers, and other software engineers to translate high-level requirements into high-quality, impactful features. You will be instrumental in the end-to-end development lifecycle: from initial design and architectural planning to implementation, testing, and deployment.

Crucially, you will act as a technical leader and custodian for the entire Android codebase. This includes establishing and maintaining best practices, code standards, and the overall technical quality of the application. You will mentor and guide other engineers, contributing to a continuous learning environment that elevates the team’s collective ability to write clean, maintainable, and performant Kotlin code, ensuring the consistent and reliable delivery of our vital Android to users globally.

This role requires a high degree of autonomy in executing complex technical tasks while collaborating effectively within a small, fast-moving team to ensure technical decisions align with the overall product vision. You will be a hands‑on contributor, focused on delivering high-quality code that directly impacts our consumer finance app for emerging markets.
