Effective communication and delegation skills are crucial, as they frequently collaborate with product managers, designers, and other engineers to align technical solutions with business goals. This balance provides opportunities for leadership growth while keeping technical skills sharp.

Familiarity with frameworks like React or Angular, back-end technologies such as Node.js or Java, cloud services, and version control systems like Git is typically required, along with experience in CI/CD and testing tools. Excellent communication, leadership, and collaboration skills help you guide teams and coordinate across disciplines.
