About the role

Key responsibilities & impact

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

What you’ll need

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.
