Drive cross-team technical initiatives, aligning frontend architecture with backend APIs, platform capabilities, and product strategy
Proactively identify technical risks and opportunities, providing clear technical direction and tradeoff analysis
Mentor and guide frontend engineers, raising the bar on code quality, architectural thinking, and delivery practices
Design and implement robust unit, integration, and UI automation tests to ensure reliability and confidence at scale
Define and monitor frontend metrics (performance, reliability, user behavior) to inform product and technical decisions

Requirements:

Bachelor’s (or higher, e.g., MS, or PhD) in Computer Science or a related technical field involving coding or equivalent technical experience
Expert-level proficiency in modern frontend development, including HTML, CSS, JavaScript, TypeScript, React, and Next.js
Strong experience with frontend architecture, including state management, component design, design systems, micro-frontends (or modular architectures), and performance optimization
Experience building and operating production web applications using server-side and client-side rendering
Deep understanding of software engineering best practices across the SDLC, including testing, code reviews, observability, and operational excellence
4+ years of industry experience, with significant depth in frontend or web platform development
