Job Description
Checkout.com is on a mission to transform the shopping experience for millions of consumers. As our most senior individual contributor in mobile, you’ll lead the development of our mobile app from the ground up. This role goes far beyond writing code - you’ll define the architecture, shape the technical foundations, and craft a high-performance, user-friendly experience at scale.
You’ll be our mobile authority, driving key decisions on tooling and component strategy. We're looking for someone pragmatic, opinionated, and deeply experienced in building mobile-first consumer products.
What You’ll Do
Lead the design and implementation of our first mobile app, with React Native as the preferred approach, while keeping flexibility to evolve the tech stack as the product matures.
Drive key architecture decisions - navigation, state management, animations, and performance tuning - ensuring scalability and maintainability.
Act as the guardian of mobile UX and performance: define what should be built in React Native and where native development is the better fit.
Partner with backend and product teams to deliver seamless, end-to-end user journeys.
Establish mobile engineering foundations - coding standards, CI/CD pipelines, testing practices, and observability - from the ground up.
Mentor future mobile hires, scale the team, and actively contribute to the hiring process.
You Should Have
8–10+ years in mobile engineering, with at least 3+ years production-level React Native experience.
Solid background in iOS or Android native development - confident extending and maintaining native modules when required.
Proven experience building and maintaining mobile apps with significant active user bases.
Deep understanding of UX, performance bottlenecks, and platform-specific edge cases.
Strong technical judgment with the ability to balance trade-offs, influence direction, and adapt the stack as needed.
Excellent communication skills and experience collaborating with product, design, and backend peers.
Experience in consumer-first industries, ideally with high-scale apps (>100K MAUs).
