Valero Energy Corporation is an international manufacturer and marketer of transportation fuels and petrochemical products, and the world's premier independent refiner. Headquartered in San Antonio, Texas, the Fortune 500 company employs approximately 10,000 people and runs 14 refineries across the United States, Canada and the United Kingdom, with a combined throughput capacity of 3 million barrels per day.
Refining is only part of the picture. Valero operates 12 corn ethanol plants in the U.S. Midwest with 1.7 billion gallons of annual production capacity, making it the world's second-largest corn ethanol producer. Through the Diamond Green Diesel Holdings LLC joint venture on the Gulf Coast, it produces renewable diesel at two plants, with up to 1.2 billion gallons of annual capacity, and co-produces Sustainable Aviation Fuel, with up to 235 million gallons of annual capacity.
The work is large-scale, continuous and safety-intensive: refineries and plants operate around the clock across multiple countries, and depend on disciplined execution and coordination between sites. Valero states that it maintains safe, reliable and environmentally responsible operations, describes itself as a leader in low-carbon transportation fuels, and is committed to advancing the future of energy through innovation, ingenuity and execution.
Roles are spread across refining, petrochemicals, renewable fuels, ethanol and Sustainable Aviation Fuel production, in the U.S., Canada and the U.K.
