About The Position

We are seeking a Senior Software Engineer to join our LRX Core team, focused on building the shared architecture and foundational layers that power Crunchyroll experiences across Smart TVs, Game Consoles, and other connected devices. In this role, you will design and implement core client frameworks, shared modules, and platform-level capabilities that enable multiple product teams to build consistently and efficiently. You will play a key role in shaping our HTML5-based architecture, driving technical direction, and ensuring performance, scalability, and reliability across devices. This role requires strong frontend expertise (JavaScript, TypeScript, React) and experience working with performance-constrained or platform-specific environments.

Deep experience with JavaScript, TypeScript, and React, including building scalable and maintainable applications.
Proven ability to design and deliver complex systems, frameworks, or shared libraries used across multiple teams or products.
Demonstrated ability to lead projects, influence architectural decisions, and drive alignment across teams.
Strong debugging and problem-solving skills, especially in cross-module or platform-specific scenarios.
Experience working with cross-functional teams and managing dependencies in distributed environments.
Ability to clearly articulate technical concepts and trade-offs to both technical and non-technical stakeholders.
