📋 Description

• 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.

🏖️ Benefits

• Healthcare Insurance: zerohash covers roughly 100% of employee premiums as well as a portion of spouse/children (U.S. only) • Vision & Dental Insurance (U.S. only) • Chance to earn equity • Maternity & Paternity leave (after 6 months) • WeWork All Access Membership • WFH Yearly Stipend • L&D Yearly Stipend (after 6 months)
