Jean Vezina

Co-founder, Managing Director

  • Caltech Unipessoal Lda
  • Caltech General Contracting Lda

A Civil Engineer from Canada, Jean has 25 years of construction experience around the world with aid organisations and the private sector. He came to East Timor in 1999 as part of a Médecins Sans Frontières emergency team, remaining in the country after leaving them in 2000 to contribute as a private contractor to the emergent nation’s re-construction effort.

“Timor-Leste is a challenging location in which to operate, hampered by its predominantly young and inexperienced labour force. The duty of an employer is to commit to closing the technological and cultural gap between the capabilities of Timorese employees and those in global industry, providing opportunities for training for success. This can be achieved by, prior to labour uptake, having an understanding of the skillset demand for projects and, from the outset, accurately identifying abilities and potential in candidates for jobs and structuring and managing their work skills development in an ongoing way using the appropriate methodologies. Proper supervision needs to be provided to ensure that the highest standards of quality and OH&S are maintained at all times during all phases of operation. The worthy calibre of Caltech’s workforce today is testament to our local knowledge and expertise in getting all of these growth elements right.”

As a company or as an individual, we invite you to be the change you wish to see in Timor-Leste.

“Timor-Leste has such a young and inexperienced workforce that for me, being in a position to put my experience to such good use not only in an operational capacity but as a mentor, is an opportunity I am proud to have.  It is exciting to not only witness the incredible advances being achieved by Caltech’s workforce, but to feel you have contributed in some small way to their progress.”
