*** Our hybrid work model is designed to give you the best of both worlds—flexibility and face-to-face collaboration. Employees are required to be present in the office on Tuesdays and Wednesdays each week. This means you’ll be in the office at least two days a week, and work remotely on the other days. This approach helps us stay connected as a team.
