American Express

American Express is a globally integrated payments company, founded in 1850 as an express delivery service and now employing more than 70,000 colleagues worldwide. It develops and operates charge and credit card products, travel services, business financial solutions and premium lifestyle rewards for consumers, businesses and merchants, with millions of customers relying on its systems daily.

Technical work spans payments technology, transaction processing, payment security, rewards and loyalty platforms, financial services infrastructure and travel services technology. The company's engineering priorities are shaped by the demands of high-volume transaction processing and the security and reliability expectations of a business that handles payments at global scale.

American Express operates across global markets and works within the financial services, payments, credit and charge cards, travel and hospitality, business services, retail and commerce, and lifestyle and rewards sectors. Beyond its product lines, the company invests in communities worldwide and states a mission of providing "powerful backing" to customers, colleagues and communities.

The firm describes itself as relationship-driven rather than purely transactional, and emphasises trust, security and innovation in how customers pay and earn rewards. Its stated history stretches back 175 years to its founding in 1850.
