The challenge
As a Senior Frontend Engineer & Team Lead, you will play a key role in owning and evolving the frontend domain within a small, highly autonomous squad. Your mission will be to define the frontend architecture, standards, and delivery practices, transforming business requirements into scalable, maintainable, and high-quality user interfaces.
You will combine hands-on development with technical leadership, acting as the reference point for frontend decisions while enabling other engineers to succeed. In this context, leadership is not about managing large teams, but about setting direction, ensuring quality, and fostering a strong engineering culture.
You will be responsible for evolving the frontend platform based on React and TypeScript, driving architectural decisions such as modular design, monorepos, shared libraries, and design systems. You will ensure consistency, scalability, and performance across applications, while continuously improving developer experience and frontend workflows.
Collaboration will be essential. You will work closely with Product, Design, and Backend teams to translate business needs into technical solutions, align on UX implementation, and define API contracts. You will also contribute to broader platform decisions, ensuring the frontend integrates seamlessly within the overall system architecture.
