Role Overview

CIBC is growing its mobile engineering team and is looking for experienced Senior React Native Developers to support multiple mobile initiatives across existing and greenfield applications.

This is a hands-on mobile development role. The majority of development will be completed using React Native and Expo, with a smaller portion requiring interaction with the native iOS/Android layers for troubleshooting, integrations, and platform-specific functionality.

Candidates must have meaningful, recent production experience with React Native. This is not intended for primarily web-based React developers who have had limited exposure to React Native.

Developers will work within Agile squads alongside Product, Design, QA, and Engineering teams, taking features from requirements and Figma designs through development, testing, and implementation.

Key Responsibilities

• Design, develop, test, and maintain production mobile applications using React Native and Expo
• Build new mobile features from requirements, specifications, and Figma designs
• Work within Agile squads alongside Product, Design, QA, and other engineers
• Own features through the full development lifecycle from requirements through implementation and QA
• Integrate mobile applications with REST APIs
• Troubleshoot issues across React Native and, when required, the underlying native iOS/Android layers
• Work with Swift/iOS development when functionality requires native implementation
• Apply established native mobile development patterns and best practices within React Native applications
• Develop automated unit/component tests using Jest and React Native testing libraries
• Participate in code reviews, technical design discussions, security reviews, and engineering standards
• Support both existing applications and new greenfield mobile development
• Contribute to CI/CD and mobile release processes using EAS Build/EAS Update, Jenkins, and GitHub Actions
• Leverage GitHub Copilot and AI-assisted development tools throughout the engineering workflow
• Participate in the team's move toward spec-driven development, using specifications from requirements through implementation and QA
• Work with emerging AI-enabled engineering workflows, including Figma MCP integrations and Spec Kit

Must-Have Skills

• Strong, recent hands-on experience developing production React Native applications
• Experience working with modern/recent versions of React Native
• Strong hands-on experience with Expo
• Strong TypeScript/JavaScript development experience
• Experience working within Agile development squads
• Ability to take Figma designs and independently translate them into production-ready mobile features
• Strong troubleshooting and problem-solving skills
• Strong communication skills and ability to collaborate effectively with Product, Design, QA, and Engineering teams

Strong Assets / Nice to Have

• Previous native iOS development experience, particularly Swift
• Native Android development experience
• Experience troubleshooting React Native issues within native mobile layers
• Experience with EAS Build and EAS Update
• Experience with Zustand and/or TanStack
• Experience with Expo-based navigation
• Experience with Jenkins and GitHub Actions
• Web application development experience
• Experience with GitHub Copilot or other AI-assisted development tools
• Exposure to spec-driven development
• Experience with Figma MCP servers, Spec Kit, or similar AI-enabled engineering workflows
• Experience developing applications within banking, financial services, or other highly regulated environments
