Senior Software Engineer

About the role

This role focuses on enhancing the user onboarding experience for Bitso, a leading cryptocurrency platform in Latin America. The Senior Software Engineer will be responsible for designing, building, and maintaining the mobile screens, navigation, and SDK integrations that guide users through signup, identity verification (KYC), and account level upgrades. This involves deep involvement in the mobile user journey from initial interaction to full account activation.

A key aspect of this position is driving React Native architecture decisions, which includes defining patterns and setting standards to ensure consistency across the mobile surfaces managed by the Registration Squad. The engineer will also manage the technical relationship with identity providers like Incode and Jumio, handling SDK integrations, version upgrades, and incident response. This requires a strong understanding of mobile SDK constraints and tradeoffs in regulated environments.

Success in this role means delivering high-quality, well-tested React Native and iOS code, championing engineering best practices through code reviews, and proactively monitoring and resolving production issues to ensure mobile reliability. The engineer will collaborate closely with Product, Compliance, and backend teams to translate regulatory requirements and user needs into robust mobile solutions, while also mentoring peers and contributing to technical discussions.

The annual salary for this position ranges from $105,000 to $175,000 USD.
