  • • You will collaborate closely with cross-functional teams, including product managers, designers, and other engineers, to deeply understand business requirements and translate them into scalable, efficient, and innovative technical solutions.
  • • You will continuously adapt to the evolving JavaScript ecosystem, identifying and implementing new tools and techniques to maximize engineering efficiency and product quality.
