Web3 Developer Senior Jobs in Europe

Working At Bitso

We are a diverse team that takes pride in understanding the perspectives of others. We fully embrace working remotely and we are eager to act, improve and accelerate progress inside and outside of our organization.

To drive revolutionary changes in society and make crypto useful, we delight our customers with world-class products, deep care, and intentional empathy.

Your Purpose

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.

Reports ToThis role reports to the Registration Engineering Manager.Who You Are

• You are experienced in React Native development, with a proven track record of shipping production mobile apps at scale across iOS and RN, with a strong depth in iOS native development.
• You have hands-on experience integrating third-party SDKs, including identity verification or biometric providers, and understand the constraints and tradeoffs of mobile SDK integration in regulated environments.
• You have designed and maintained mobile architectures that are testable, maintainable, and resilient to the rapid iteration cycles of a fintech product.
• You are comfortable working across the mobile/backend boundary, understanding REST APIs, async flows, and how mobile state interacts with backend systems.
• You communicate complex technical decisions clearly in English, written and spoken, to engineering peers, product managers, and senior leadership.
• You work with a high degree of autonomy and ownership. You identify problems, propose solutions, and see them through to production.

What You Will Do

• 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.
