Founded in 2012,\nJuspay processes over 350M+ of India’s daily digital transactions, exceeding an annualized TPV of $1 trillion with\n99.999% availability. Headquartered in Bangalore, India, Juspay’s global network of 1500+ payment experts operates\nacross San Francisco, Dublin, São Paulo, and Singapore.\nJuspay offers a modular, interoperable payment suite for merchants, banks and payment networks, covering open-source\npayment orchestration, authentication, offer management, subscription, tokenization, fraud & risk management, global\npayouts, reconciliation, and analytics. For banks, Juspay delivers real-time payment infrastructure (UPI stacks) and\nend-to-end white-label merchants acquiring solutions and payment gateways. Our marquee partners include Google Pay,\nAmazon Pay, Flipkart, IRCTC, Navi, Swiggy, WhatsApp Pay, Mastercard, Visa, NPCI, and more.\nNationwide Impact & Ecosystem Building\nOver the past decade, Juspay has been a core enabler of India’s digital payments revolution by building infrastructure,\nprotocols and frameworks that now serve billions of users. We work as a Technology Service Provider (TSP), connecting\nmerchants, banks, and fintechs through secure, interoperable, and scalable payment systems.\nKey Highlights:\n\nBHIM & UPI Infrastructure: Partnered with NPCI to develop the UPI Common Library SDK and BHIM UPI App, enabling\nseamless and reliable UPI transactions across India. Juspay also designed the UPI Common Pin Page, now used for\nevery UPI transaction nationwide.\n\nOpen Ecosystem Platforms: Built open-source frameworks like HyperSwitch (a goal towards ‘Linux for Payments’),\nHyperSDK, and HyperCheckout, empowering developers and merchants with flexibility, transparency, and full control.\n\nNational Digital Initiatives: Contributed to India’s open network efforts through projects like OCEN / HyperCredit (digital\ncredit infrastructure) and ONDC / Namma Yatri (open mobility platform on the Beckn protocol).\nEngineering at Juspay\nAt Juspay, engineering is our core differentiator. We design high-assurance, real-time systems that power over 350M+\ndaily transactions with 99.999% availability. Our engineering organization is structured around Centers of Excellence\n(CoEs) that focus on the dual goals of framework innovation (the Ideal) and business enablement (the Practical).\n\nSDK Engineering: From Presto to HyperSDK, we build secure, native frameworks that power seamless payment\nexperiences for partners like Google Pay & Amazon Pay.\n\nBackend Systems: Our in-house KvDB (write-back cache db) sustains 100× traffic spikes with zero downtime, ensuring\nreliable performance during India-scale surges.\n\nIntelligence Systems: Juspay’s AI engine turns live payment data into real-time routing decisions, using control-theoretic\nfeedback loops and multi-arm RL bandits to dynamically steer transactions toward the most reliable gateways and\ncontinuously optimize success rates. (Read more in the published research paper: “A Control-Theoretic Approach to\nDynamic Payment Routing for Success Rate Optimization”)\n\nInfrastructure & Platform: Multi-region, active-active architectures, on-prem + cloud deployments, and internal\nframeworks like InfraSwitch, A/B & ART on production data ensure always-on reliability and zero-downtime evolution.\nWhat Will Your Work Look Like?\nAt Juspay, you’ll work on deep-tech projects that blend AI, systems engineering, and first-principles design to solve\nchallenges at the intersection of finance, infrastructure, and intelligence.\n1.
