Role
Who you are
- We are looking for an exceptional mobile platform engineer with deep React Native expertise and proven Staff-level leadership
- 15+ years of professional software engineering experience, with significant depth in mobile development
- 8+ years of hands-on React Native experience, including large-scale production apps
- Deep expertise in mobile architecture, performance optimization, and native platform integration (iOS/Android)
- Strong command of TypeScript, React, and modern application engineering practices
- Proven experience building platform foundations, shared libraries, design systems, or developer frameworks that enable other teams
- Experience designing and scaling monorepo architectures and cross-team ownership models
- Strong understanding of testing, release safety, observability, and operational excellence in mobile environments
- Expertise in developer tooling, CI/CD pipelines, and mobile release infrastructure
- Ability to influence across teams and domains, aligning engineering leaders around shared standards
- Track record of mentoring senior engineers and driving organization-wide technical change
- Experience operating in high-reliability or regulated environments (fintech experience is a plus)
- Strong passion for bridging mobile and web platforms through shared foundations and consistent user experiences
What the job involves
- To enable this, we are hiring a Staff React Native Specialist at domain level
- This is a highly strategic and deeply technical role reporting directly into the Merchant Experience Domain Lead, with impact spanning multiple teams and domains
- You will own the foundations of our React Native platform: the low-level architecture, performance, developer experience, and monorepo strategy that will allow Mollie to scale mobile development across the organization
- This role is about building the system that enables everyone else to build faster
- As a Staff React Native Specialist, you will operate as the domain-wide technical authority for React Native and mobile platform foundations. Your responsibilities will include:
- Owning Mollie’s React Native architecture at the deepest level, ensuring long-term scalability, performance, and maintainability
- Driving the next evolution of our mobile platform by establishing a monorepo and shared foundation that enables every team to ship cross-platform features independently
- Defining the standards, patterns, and best practices that will allow Mollie to scale React Native development across many teams without fragmentation
- Building and maintaining core platform modules: navigation, authentication, localization, offline support, observability, performance tooling, and shared UI primitives
- Ensuring seamless feature parity and consistency between Mollie’s mobile and web experiences
- Partnering with engineering leaders across domains to enable distributed feature ownership while maintaining a coherent platform
- Leading technical initiatives that reduce complexity, improve release confidence, and raise the overall quality bar of Mollie’s mobile ecosystem
- Mentoring senior engineers and acting as a multiplier across the organization through coaching, design reviews, and architectural guidance
- Serving as a key driver of Mollie’s long-term mobile strategy as we transition from centralized delivery to domain-owned, cross-platform execution
- Mollie’s frontend ecosystem spans multiple applications, including our merchant dashboard, mobile apps, and developer-facing experiences
- Our stack includes:
- Mobile: React Native + TypeScript, evolving toward shared domain-owned feature modules
- Frontend: React, TypeScript, component-driven development
- Backend: Primarily PHP & Java, deployed in Google Cloud
- Infrastructure: Service-based architecture, supported by queueing systems
- Developer Experience: Strong investment in internal tooling, CI/CD, and platform consistency
- This role will be foundational in shaping how Mollie builds mobile software at scale for the next decade
