Profile bio

About Rosa Bui

Rosa Bui is a Senior Human Resources Generalist at 24M Technologies at 24M Technologies. She is proficient in Vietnamese. Colleagues describe her as "I had the pleasure of working closely with Rosa for the two years I ran the Human Resources Department at OpenSymmetry. During that time, I often leaned on Rosa to help me understand business processes and to own entire functions within the department, such as annual open enrollment for employee benefits, 401K administration, and payroll. It would be impossible to count the number of times my reply to a question was, “I’ll need to ask Rosa,” because I knew she had likely encountered the issue before or I wanted her input before I responded. Furthermore, I could trust Rosa to exercise utmost care and discretion in handling confidential and sensitive matters. Even when times were stressful, Rosa always came into work with a great attitude. All of this made her a great asset to my team.", "Rosa is amazing to work with. Not only is she diligent, thorough, and quick to respond to any HR needs, but she also has such a cheerful personality that really impacts the culture. I can rest easy whenever I send requests to her, knowing she will be on top of it, which is an indicator of her integrity and character. I am confident she would thrive in just about any team.", and "I had the pleasure to work with Rosa for over 4 at OpenSymmetry and 3 years in the Human Resources department working together as we grew and evolve our services offered. When the full weight of the HR duties were given to Rosa she handled it extremely well in her typical, calm and thoughtful approach. Rosa was large part of the evolution of our HR services over several organizational structure changes, benefits changes, policy updates, and implementing new HR ticketing systems to better serve our employees. Rosa takes a very consistent and successful approach of remaining calm, asking smart questions at the right time, and successfully implementing change. It was pleasure to work with Rosa over last 4 years."
