Staff Software Engineer (Web Automation & Open Banking Infrastructure)

Zero Hash is the leading crypto and stablecoin infrastructure platform and the operating system for digital money, powering the next generation of financial services. They are seeking a Staff Software Engineer to architect and build their open banking data aggregation platform, focusing on complex web automation and browser internals.

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 platform at every step, adapting quickly to dynamic DOM changes, varying mobile/desktop portal structures, and application suspension states
• Introduce industry-leading engineering patterns and practices that give us the confidence to operate at scale
• Support the engineering team in achieving a high level of technical excellence, actively mentoring senior and mid-level engineers

Requirements:

• 10+ years of hands-on software engineering experience, deeply focused on advanced web automation, browser internals, extension development, or complex frontend-to-backend data extraction
• Deep proficiency in TypeScript and JavaScript, specifically regarding deep DOM manipulation, modern web APIs, and strict browser execution environments
• Strong backend experience, ideally with Golang (or Node.js/Python), to design the centralized WebSocket routing hubs and operational infrastructure
• Strong security fundamentals: you deeply understand secure message passing across trust boundaries (JS bridges, isolated vs. main worlds), secure authentication handshakes, and mitigating DOM-based injection risks
• Expertise in analyzing complex network architectures and single-page applications (SPAs) to establish resilient data ingestion pipelines without relying on brittle UI selectors
• Experience with distributed systems, specifically managing persistent connections and stateful, multi-hop sessions across ephemeral client runtimes
• Comfort with ambiguity; the ability to independently lay out and test clear hypotheses and solve problems without well-defined direction
• BS or MS degree in Computer Science or Engineering OR equivalent years of work experience
• Proven track record of developing production-grade browser extensions (Chrome MV3) or integrating complex web automation within mobile native environments (iOS WKWebView, Android WebView)
• Strong understanding of WebAuthn / Passkey protocols and how to integrate them into automated flows
• Previous engineering experience at a major financial data aggregator or building zero-knowledge/client-side data extraction tools
• Understanding of cryptocurrency and blockchain technology, including major protocols, on-chain transaction flows, and common crypto security practices
