Vix Technology operates one of the largest attack surfaces in critical infrastructure you've probably never thought about: public transit payment systems. The company builds and deploys intelligent transportation systems and automated fare collection platforms across more than 200 cities, with over 500,000 devices in the field spanning APAC, Europe, and North America. When you're processing fare transactions at that scale - account-based ticketing, mobile payments, real-time passenger information - the threat model is broad: financial fraud, data exfiltration of rider PII, device tampering, and disruption of essential urban services.
The product stack includes account-based ticketing systems, mobile payment infrastructure, real-time passenger information displays, and transit analytics platforms. Each layer presents distinct security challenges: securing payment processing pipelines against credential stuffing and transaction replay, hardening embedded devices deployed across citywide networks, protecting analytics datasets containing granular movement patterns of millions of riders. The company has a team of 450+ across its global footprint.
Culturally, the company signals a pragmatic operational ethos - "think like a customer," "focus on what matters," "stay smart and curious" - alongside a stated commitment to net zero emissions. For security engineers, the draw is the intersection of physical and digital infrastructure at scale: embedded systems, payment security, cloud analytics, and IoT fleet management all converging on systems that cities depend on daily.
