Full-Stack Engineer (Mobile App)
About The Position
What You’ll Do Build and evolve a greenfield mobile and web application using React and React Native, delivering secure, responsive, mobile-first user experiences. Design and implement production-grade backend services using Node.js / Express with TypeScript, including REST API design, PostgreSQL integration, authentication (OAuth/OIDC), and robust server-side architecture. Maintain deep type safety across client and server codebases, leveraging shared schema validation (Zod or similar) and consistent API contracts. Develop responsive, accessible, mobile-first UIs using modern React patterns and state management approaches. Own end-to-end delivery: feature development, testing, performance optimization, release management, monitoring, and iterative improvement. Establish foundational engineering patterns and best practices for a team experienced in web development but new to native mobile. Mentor teammates and help define scalable architecture patterns across frontend and backend layers. Manage mobile build and deployment workflows, including publishing to the Apple App Store and Google Play Store. Navigate app store submission processes including signing, provisioning, certificates, release tracks, and compliance with platform review guidelines. Coordinate with government security and compliance stakeholders to meet required approval gates and documentation standards. Implement secure coding practices and support review, remediation, and compliance-driven updates. Troubleshoot production issues across frontend, mobile, and backend systems and drive root-cause resolution. Maintain clear technical documentation covering architecture, release workflows, and operational processes.
