Description

About this role 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.

Experience working with microfrontends and modular frontend strategies. Leading frontend development practices, including code reviews, testing, and performance optimization. Collaborating with cross-functional teams (Product, Design, Backend) to deliver high-quality solutions. Key skills and expected impact: Ability to translate business and product requirements into robust, scalable frontend solutions. Strong understanding of frontend architecture principles: Domain-Driven Design (DDD) Hexagonal architecture SOLID principles Deep knowledge of the React ecosystem and modern frontend tooling. Experience with design systems and atomic design principles. Strong focus on performance, accessibility (a11y), and user experience quality. Ability to ensure code quality, maintainability, and observability across the frontend. Strong mentoring and leadership skills: enabling others through feedback, pairing, and guidance. Ownership mindset with the ability to drive initiatives from concept to delivery. Pragmatic decision-making: balancing long-term architecture with short-term delivery needs. Strong communication skills to align with both technical and non-technical stakeholders.
