I will pre-pend my answer with a caveat: this is probably localized.
What I know is based on experience working in North America.
Do translate the degree on your resume to English (B.Eng in Computer Science). Recruiters want to easily categorize you, and this is something that they are familiar with.
Also keep in mind that you will probably have to do the following things if you apply to large corporations that care about all of the paperwork:
1) Some companies will require degrees/diplomas to be legally translated or notarized by local notaries. This is fairly easy, you find someone in the area, pay them some money, wait for about a week and all is well.
2) Some companies will require a foreign degree to be validated by a local college/university. The process involves paying some money and having a local well-known institution asserting that your degree of Ingeniero Técnico en Informática is roughly equivalent to their B.Eng in Computer Science. I know someone for whom this took 1.5 months. Your mileage may vary because it completely depends on the bureaucratic complexity of the institution in question.
Sometimes these things need to be done before they can officially onboard you. Keep this in mind, as it may delay your working start date or cause unexpected hiccups.
