About Oculon Systems

Oculon Systems builds client-intake infrastructure for law firms.Our product, Iris, sits directly on a law firm's website and engages prospective clients 24/7. It asks the follow-up questions that distinguish a strong case from a weak one, structures the information collected during the conversation, and delivers a clear summary to the firm's inbox — with the facts, urgency, and next steps attorneys need to act.Law firms miss potential clients when nobody is available to respond.Iris handles the initial intake conversation so attorneys can focus on the case.We are an early-stage company. The team is small, communication is direct, and what you build here ships.We are now looking for a Frontend Developer : React / Next.js / TypeScript to build the interfaces and experiences through which law firms and their prospective clients interact with Iris.
