Transaction Network Services, Inc. (TNS) is a global provider of mission-critical Infrastructure-as-a-Service (IaaS) solutions, connecting financial institutions, communications providers and payment companies across more than 60 countries. Founded in 1990, the company has spent over three decades building and operating network infrastructure designed for reliability at scale: billions of dollars in financial trades, payment transactions and voice communications pass through the TNS Global Network every day.
TNS's technical work spans several demanding domains, including network infrastructure and high-availability network engineering, telecommunications and voice communications, call authentication, trading infrastructure and direct market access, market data connectivity, and payment security and fraud prevention. Engineering roles touch problems such as real-time fraud detection, voice and call-authentication systems, and low-latency connectivity - areas where machine learning and data-driven methods are increasingly applied to detection, classification and anomaly identification at scale.
The company organises its offering around three solution areas. Communications solutions cover robocall protection, call authentication, carrier connectivity and voice services. Financial Markets solutions provide trading infrastructure, direct market access and market data connectivity for exchanges and trading firms. Payments solutions handle secure payment acceptance, fraud prevention and device connectivity across payment ecosystems.
With a presence spanning the Americas, Europe and Asia, TNS describes its engineering culture as rooted in mission-critical reliability and in combining deep telecommunications expertise with newer technology. The stated goal of its communications work is restoring trust in voice communications; across the business, the emphasis is on keeping essential transactions running without interruption.
