Carlos joined the Trust in 1997, having previously worked around the Middle and Far East as a specialist in fire detection systems.
Since then, he has been part of the medical electronics team, who are responsible for maintaining a wide range of electronic and mechanical equipment.
Carlos said: "We look at everything, from breast pumps to the heart and blood monitors in intensive care - no two days are the same. Sometimes we'll spend the majority of our time carrying out scheduled tests on equipment, but other days might see us responding to emergency call outs. It's all a matter of juggling priorities."
Despite his job title, Carlos isn't strictly confined to working with electronic equipment. As he explains: "We also deal with the mechanical side of things. One example is the checks we perform to make sure there are no bolts or screws loose on examination couches and furniture around the wards.
"Then there are other jobs, such as updating inventories and conducting site surveys. These tell us what we've got and where it is, and we travel all over the place to get this done.
"I also help staff to use and understand their equipment, especially if it's something new. Most people are well trained anyway, but coming from a technical standpoint, there's always the odd tip I can impart."
And with almost a decade and a half working in the medical electronics team, Carlos remains unfazed by the ever-changing face of technology.
As he explains: "Advances are always being made, and members of the team regularly attend courses to keep on top of new developments. Fundamentally though, whatever the gadgetry, equipment will always need testing - and repairing."
Outside of work Carlos spends much of his spare time caring for his disabled son, and when he gets the chance, follows the fortunes of Chelsea FC.
