Working closely with backend teams to ensure the underlying systems we build are aligned to support our mobile product evolution.
Championing best practices across the technical domain (testing, monitoring, release strategy, etc) to strengthen our foundations as we build our products.
Mentoring peers, reviewing code, and contributing to the long-term technical vision for mobile development at Checkout.com.
Should have
Solid background in React Native, building scalable and highly performant consumer experiences.
Proven track record building across the mobile domain (e.g. experience with native iOS and Android).
Experience building and maintaining mobile apps or SDKs used by a large, active, user base.
Passionate about developer experience – clear APIs, great docs, and reliability at scale.
Excellent communication skills and experience collaborating with product, design, and backend peers.
Nice to have
Previous experience in payments, fintech, or other security‑sensitive domains.
Exposure to PCI compliance, tokenization, or secure data handling.
