Da Silva joined Arup Group as a graduate engineer in 1989.[6] She was part of the development of the Hong Kong International Airport and National Portrait Gallery, London.[7] She began to work in post-disaster engineering in 1991.[6] In 2001, she was selected as one of Management Today's 35 Women Under 35.[8] She has investigated the relationship between populations and the built environment, in particular the role of infrastructure in reducing vulnerability.[9][10]
In 2009, da Silva founded the Arup International Development group, a non-profit subsidiary of Arup Group which works with organisations that look to improve the coordination of infrastructure development in the developing world.[11] She is a member of RedR, Engineers for Disaster Relief, a charity which has thousands of engineers who will respond quickly after a disaster.[12] Arup encourage humanitarian efforts to build back better, preventing homes being destroyed when floods or disasters return.[13]
Da Silva is a specialist in disaster reduction and has worked with various humanitarian groups. She worked with the United Nations High Commissioner for Refugees (UNHCR) in Sri Lanka after the 2004 Indian Ocean earthquake and tsunami.[14] She coordinated the efforts of over 100 humanitarian agencies and the building of over 60,000 shelters in six months.[5][15] From 2008 to 2017, she worked with Sabre Education to develop a series of early-years learning facilities in Ghana.[16][17] The work was supported by the Institution of Civil Engineers.[18] She has since been working with the World Bank on a Global Program for Safer Schools.[19] Da Silva worked with Tower Hamlets Council on Ideas Stores, a way to bring IT facilities to communities in East London.[5]
She is founder and on the Board of the Lloyd's Register and Arup-supported global programme to accelerate critical infrastructure resilience, "The Resilience Shift",[27] which stimulates improved resilience and whole-system thinking through thought leadership, grant making, and convening.[28]
