Descripción del empleo

The role asks for an engineer who can build and run user interfaces for a secure platform, working mainly in React and TypeScript plus native mobile in Swift or Kotlin. A strong candidate brings production experience across web and mobile, solid API integration skills, and a habit of owning features from design mockups through deployment and monitoring. Care for accessibility, testing, and client side security matters more than speed alone.

How it fits the AI era

AI tools can speed up component scaffolding, test writing, and debugging, so the job shifts toward judgment about architecture, security boundaries, and user safety. The human parts stay central: reasoning about trust boundaries, data leakage, and how operators move through critical workflows under pressure. Interfaces for sensitive work still need careful design and accountability that tools cannot supply.

How it builds AI experience

Working here means building interfaces for environments where organizations run AI and sensitive workloads under their own control, so the experience gained is in designing clients that handle data carefully and stay reliable offline. Candidates can prepare by practicing secure token handling, encrypted local storage, and offline sync in personal or open source projects. Familiarity with client side cryptography or zero knowledge protocols would strengthen a case.

Worth showing

• React and TypeScript
• Native iOS or Android
• Secure client side patterns
• API and real time data
