Littlepay processes over USD 1 billion annually in transit payments across 13 countries via contactless cards, mobile wallets, and wearables. The tech stack (AWS, Go, Java, PostgreSQL, DynamoDB, Lambda, SQS) is built for high-throughput transaction processing, and active projects around transaction scaling, acquirer integrations, and incident automation signal heavy infrastructure-layer work. Security hiring (2 open roles) alongside engineering and product reflects both growth stage and regulatory complexity in fintech.

About Littlepay

Littlepay is a Melbourne-based fintech providing payment infrastructure for public transit operators and mobility services. The platform allows passengers to tap any payment method—card, phone wallet, or wearable—rather than dedicated transit cards. Operating across Australia, UK, EU, LATAM, and USA, the company has built a distributed payments backbone that handles high-frequency, low-value transactions at scale. Customers range from municipal transit agencies to mobility operators seeking simpler fare collection.
