About the role

About Fam (previously FamPay) Fam is India’s first payments app for everyone above 11. FamApp helps make online and offline payments through UPI and FamCard. We are on a mission to raise a new, financially aware generation, and drive 250 million+ young users in India to kickstart their financial journey super early in their life. We’re reimagining how the next generation experiences fintech—going beyond payments to build a lifestyle brand that blends money, identity, and everyday experiences into one seamless, intuitive journey. Founded in 2019 by IIT Roorkee alumni, Fam is backed by some of the most respected investors around the world like Elevation Capital, Y-Combinator, Peak XV (Sequoia Capital) India, Venture Highway, Global Founder’s Capital and the likes of Kunal Shah, Amrish Rao as angel investors. About the team The Core Infrastructure team builds the platforms and systems that power everything at Fam, from real-time app experiences to high-volume payments. It operates as a small, high-leverage team with deep ownership. Every service at Fam runs on the platform this team builds, so it cares obsessively about system fundamentals, operational excellence, and mechanical sympathy. What our systems process 1 Billion+ API requests per day powering ~10M daily transactions for 10M+ users at 20,000+ RPS. 470+ node Kubernetes cluster (~2,500 vCPUs and ~8 TiB RAM) under active orchestration. Dynamic, multi-dimensional auto-scaling powered by 195+ HPAs paired with Karpenter. 12+ TB of active transactional data (and counting) across our high-throughput database clusters. Event Streaming - 400+ topics, and 3,800+ partitions at ~46,700 messages/sec Our Next Chapter While our core systems already handle massive scale, our next vision as a team is to turn infrastructure into a frictionless platform discipline. We are building towards a world where internal engineering teams consume platform primitives compute, storage, and event streams via self-serve contracts without waiting on us. We're also laying the groundwork for AI-native platform operations, developing agent plane and agent skills so agents can safely interact & operate infrastructure primitives alongside our team. We look to the CNCF landscape for best-in-class tools our systems, with a long-term commitment to contributing back to open source.
