Senior Engineer, Mobile Apps

You will spearhead the migration of two native apps into a single cross-platform codebase, working autonomously to define strategy, make architecture decisions, and deliver production-ready mobile features. You will use AI-assisted tools and Figma-to-code workflows to accelerate development, write comprehensive tests, enforce security and quality standards, and collaborate directly with product managers, designers, and stakeholders to translate requirements and resolve risks.

• Identify risks, propose trade-offs, and keep stakeholders informed
• Use AI coding assistants to accelerate code generation, refactoring, and test authoring
• Leverage Figma-to-code workflows to scaffold UI components from designer handoffs
• Write and maintain comprehensive unit and widget tests
• Collaborate with product managers, business stakeholders, and designers to translate needs into technical solutions
• Participate in design reviews and provide early technical feedback
• Own app architecture decisions including state management, navigation, and data layer

• Experience in the financial sector, ideally crypto, DeFi, or digital assets (nice to have)
• Familiarity with MCP and Figma API integrations for automated UI code generation (nice to have)
• Knowledge of security and compliance for financial apps including end-to-end encryption, secure key storage, biometric authentication, and GDPR (nice to have)
