Senior React Native Engineer
Job description
About the role
You own the mobile evolution for this global finance platform, shaping how modular apps launch on iOS and Android. This role demands hands-on craft, clear tradeoff calls, and steady delivery under tight market pressure. You turn vague ideas into solid technical paths that scale worldwide. You will architect shared modules that feed many consumer apps, streamlining logic across web and native flows. This position requires designing contracts between teams so modules stay interchangeable, reducing friction during integration and release. You will orchestrate cross-functional projects from discovery through launch, coordinating design, backend, and product stakeholders. In day to day work, you translate messy product goals into structured plans that balance delivery speed, quality, and future scalability.
