Marcos Mashiba was born in 1984 in the countryside of São Paulo state, Brazil. He married Carolina in 2014, and together they have a daughter, Luísa, born in 2015.
He graduated in Mechanical Engineering from São Paulo State University (UNESP), Ilha Solteira campus, in December 2006. In March 2007, he joined Petrobras as part of the first class of the company’s engineering training program in Subsea Engineering. In 2011, he completed his master’s degree in Mechanical Engineering at the Federal University of Rio de Janeiro (UFRJ), with research focused on the performance of subsea gate valves.
Recognized for his expertise, Marcos was appointed as a Technical Advisor at Petrobras in 2012, becoming a reference in the discipline of subsea valves and actuators (V&A). He worked for nine years at Petrobras’ Research and Development Center (CENPES), leading the qualification processes for subsea valves and actuators. In 2016, he moved to the Subsea Equipment Engineering Department, where he spent over eight years working across all design phases—from specification to field support—on equipment such as XMTs, PLETs, PLEMs, manifolds, SSIVs, and P&Bs, always with a focus on V&A.
Since October 2024, after being moved from the Subsea Equipment Engineering Department to the Compliance and Technological Implementation Department, his role as Technical Advisor has been focused on the development and qualification processes for implementation of new technologies in subsea systems. Marcos represents Petrobras in the IOGP Subsea Engineering Subcommittee, where he also serves as a Subject Matter Expert (SME) for subsea valves and actuators since 2019, contributing to the development of specifications S-708 and S-731 under the JIP33 initiative, in collaboration with leading global oil and gas companies.
