Senior/Lead Frontend Engineer

Company Description Renda is a pre-seed Canadian fintech company building an AI-native banking platform designed to fundamentally rethink how people interact with money. Rather than layering digital interfaces on top of traditional banking systems, Renda is built from first principles, creating a financial experience that is intelligent, adaptive, and user-first. We operate at the intersection of financial services and AI, using large language models to interpret financial behavior, anticipate needs, and deliver clear, actionable insights in real time. We've built our beta, established our banking infrastructure, and are preparing to bring Renda to market. At this stage, we're focused on accelerating growth, building strategic relationships, and raising our pre-seed round to support our next phase of expansion.
