Lead Frontend Engineer (React) - Build Enterprise UI

The Walt Disney Company; Tandil; Presencial; ARS 184.649.000 - 276.974.000; Jornada completa

Descripción de la vacante

The Walt Disney Company in Argentina is seeking a Lead Software Engineer (React) to build the UI surface of the AI-enabled D-Fi platform for finance teams. You will own the React frontend, authentication, IAM end-to-end, and accessibility standards, while shaping UX through user feedback and cross-functional collaboration.

You will work on enterprise-grade web apps with strong focus on performance, security, and scale, collaborating with product and finance stakeholders.

Formación

• 7+ years of software engineering experience, with deep expertise in modern frontend development.
• Advanced level of English (must).
• Bachelor's degree in Computer Science, Engineering, or related field; advanced degree a plus but not required.
• Demonstrated experience owning a user-facing product end-to-end, including direct incorporation of user feedback into the roadmap.
• Strong product sense — comfort making UX judgment calls, not just implementing specs handed to you.
• Experience building role-based or permission-aware UI in a multi-persona application.
• Background building internal tools or enterprise applications is a plus, but not required — genuine curiosity about the finance domain is.

Responsabilidades

• Own the product surface layer. Build and maintain the React-based frontend across all product surfaces that finance workers and budget owners use daily.
• Own the UX iteration cycle. Incorporate feedback from UAT sessions with real users, translate that feedback into concrete product improvements, and ensure every release is measurably simpler and faster than what it replaces.
• Own authentication and access. Build and maintain SSO integration and role-based UI rendering — what each persona sees and can do within the platform.
• Own identity and access management (IAM) end-to-end. Ensure a person's Disney identity is established correctly at authentication, that their data entitlements are honored consistently as that identity flows through the platform, and that when an agent acts on a user's behalf, it correctly assumes that user's identity and permissions rather than its own — no agent action should ever grant a user more access than they'd have acting directly.
• Own performance and accessibility standards. Set and enforce the bar for how fast and how usable the application is across every surface.
• Make autonomous agent actions visible. Design UI patterns that clearly surface what agents have done, what's pending human review, and what requires action — closing the loop between autonomous backend work and the humans who oversee it.
