Senior Mobile Software Engineer

Role Description

At Bitso, the Senior Mobile Software Engineer on the Registration Squad owns the identity verification and onboarding experience across iOS and React Native, the entry point for every user who joins Bitso. You will design and deliver reliable, high-quality mobile flows that connect users to KYC providers, guide them through identity verification, and ensure compliance across multiple markets (MX, BR, CO, AR, GI, US).

Working closely with product, backend, and compliance stakeholders, you will shape the technical direction of a domain where quality, security, and user experience are non-negotiable, and where your work directly determines whether a user can access financial services.

Qualifications

• Experienced in React Native development with a proven track record of shipping production mobile apps at scale across iOS and RN.
• Strong depth in iOS native development.
• Hands-on experience integrating third-party SDKs, including identity verification or biometric providers.
• Understanding of the constraints and tradeoffs of mobile SDK integration in regulated environments.
• Designed and maintained mobile architectures that are testable, maintainable, and resilient to rapid iteration cycles of a fintech product.
• Comfortable working across the mobile/backend boundary, understanding REST APIs, async flows, and how mobile state interacts with backend systems.
• Ability to communicate complex technical decisions clearly in English, both written and spoken, to engineering peers, product managers, and senior leadership.
• Work with a high degree of autonomy and ownership, identifying problems, proposing solutions, and seeing them through to production.
• Strong sense of urgency and comfort operating in a fast-paced, high-stakes fintech environment where compliance and user trust are on the line.

Requirements

• Familiarity with KYC/AML flows, identity verification providers (Incode, Jumio, IDWall, or similar), or onboarding funnels in regulated financial products.

What You Will Do

• Own KYC and onboarding mobile flows: design, build, and maintain the screens, navigation, and SDK integrations that take a user from signup through identity verification and level upgrade.
• Drive React Native architecture decisions: define patterns, set standards, and ensure consistency across the mobile surfaces owned by the Registration Squad.
• Integrate and maintain identity provider SDKs: own the technical relationship with providers like Incode and Jumio at the mobile layer, including version upgrades, migration work, and incident response.
• Deliver high-quality code: write clean, well-tested React Native and iOS code and champion engineering best practices through code reviews.
• Ensure mobile reliability: proactively monitor, debug, and resolve production issues with a focus on root-cause analysis and lasting fixes.
• Collaborate cross-functionally: partner with Product, Compliance, and backend engineers to translate regulatory requirements and user needs into sound mobile solutions.
• Mentor and uplift: share knowledge with fellow engineers, contribute to technical discussions, and raise the bar for mobile craft within the squad.

Benefits

• Me Time program, including unlimited paid time off.
• Remote-first work environment.
• Employee Stock Option program.
• Zero trading fees through our Bitso Alpha app.
• Extended Family Leave Policy: all birthing parents, non-birthing parents, and adopting parents are eligible for a 4-month leave.
• Premium health, dental, and life insurances in Mexico, Gibraltar, Colombia, USA, Brazil, and Argentina.
