Validation engineers make sure that instruments and equipment work correctly and accurately. They work with equipment where precision is very important.

Validation engineers help to install new equipment. They take exact measurements and calibrate (or validate) the new equipment to ensure it is working to precise standards. They often train technicians to use the equipment. After equipment is installed, validation engineers troubleshoot if there are any problems with it.

Engineers keep detailed records and provide this information to those who work with the equipment. They need to be very detail-oriented and have good math, science, and computer science skills.

Validation engineers often work in biotechnology and medical fields. The green sector of the economy also requires these specialists to make manufacturing more efficient and to fine tune equipment.
