Staff Software Engineer (Web Automation & Open Banking Infrastructure)

About this role

## About the Job

Zero Hash is looking for a Staff Software Engineer to architect and build our open banking data aggregation platform, scaling our gateway to Finance 2.0. We are a high-performing team looking for an equally ambitious and driven teammate. The right candidate for this position is detail-oriented, deeply technical, and driven by the challenges of complex systems and browser internals.

Because many traditional banking APIs are not public, this role is critical to our infrastructure. You will be responsible for building a distributed, client-side automation engine. Rather than relying on traditional server-side scraping, you will build secure, agent-based infrastructure (e.g., Chrome Manifest V3 extensions, iOS WKWebViews) that communicates with our centralized backend via persistent WebSockets. You will tackle complex technical challenges, applying strong security fundamentals to navigate strict execution environments, intercept network traffic securely, and transform unstructured web data into programmable APIs that bridge traditional finance and digital assets.

## Responsibilities

• Architect and build the core automation runtime, focusing on resilient UI interactions, reliable programmatic data entry, and robust session routing.
• Design and implement secure network interception layers to seamlessly capture and parse underlying financial data streams without relying solely on fragile UI elements.
• Build and maintain high-performance communication protocols that connect our distributed client-side agents to a centralized backend routing hub.
• Develop elegant solutions to navigate complex, multi-step authentication flows—such as MFA and Passkeys—by seamlessly bridging background automation with user-facing interactive prompts.
• Navigate and engineer around the strict execution boundaries, security sandboxes, and ephemeral lifecycles inherent in modern browser and mobile webview environments.
• Build resiliency and scalability into the pl...
