After earning her degree in mechanical engineering, Marxileni Macasaet Lapuz, also known to her colleagues as Xye, spent several years exploring different paths before discovering her passion for sustainability in the construction industry.
“I looked for roles that would challenge me,” she says. “Three years after university, I found my niche in the construction industry.” She went on to work on over 20 projects as a LEED Accredited Professional in Manila, including hospitals, residential developments and pharmaceuticals.
A Workplace That Invests in Development
Today, as Principal Sustainability Engineer at Black & White Engineering, Xye is applying her expertise to one of the most complex sectors data centres. “Improving energy performance for such energy-intensive buildings is no small task,” she explains. “But it’s also what makes the work so rewarding.”
Xye joined Black & White just over two years ago and cites the company’s commitment to professional development as a major reason she enjoys her role.
“Black & White dedication to lifelong learning and professional growth is one of the things I appreciate most about my current role. This investment creates a culture that inspires everyone to achieve success and be creative,” she says.
Earning Respect Through Persistence and Technical Skill
In the early stages of her career, Xye encountered real challenges. “When I worked with teams in the Middle East, I was excluded from meetings simply because I was a woman. My opinions were dismissed,” she recalls. Instead of being discouraged, she stayed focused. “I worked hard until my senior engineers recognised my abilities and included me as a valuable member of the team.”
Xye is quick to credit the mentors who supported her development. “My former managers saw my potential and provided the environment in which I was able to develop my skills further and gain more confidence in carrying out my work.”
As an active member of the Women’s Engineering Society (WES), supported by Black & White. Last year, Xye was named one of the Top 50 Women in Engineering in the UK. “That recognition really encouraged me to engage more deeply with the WES community and continue advocating for women in engineering,” she says.
Bringing Sustainability to Life for the Next Generation
Xye is currently authoring a children’s book on green buildings for the Lottie Tour, a WES initiative designed to introduce engineering careers to girls. “It’s about sparking curiosity early. I want young minds to understand how engineering can help develop greener buildings and a more sustainable future.”
Her message is clear: “Read, write, stay informed. The glass ceiling is a myth if you’re prepared to keep going. Your success depends on your effort and determination.”
