• Facilitate alignment and clarity across teams for complex, multi-team projects.
• Spearhead technology transformation from a 'feature factory' to a platform-driven system.
• Partner with Design Systems teams to influence shared UI components and design tokens.
• Identify and reduce systemic technical risks through hands-on reviews and prototyping.

✅ What You'll Need

• 15+ years of experience as a senior/principal-level software engineer with deep frontend architecture expertise.
• Proven success leading technology transformation across large organizations (80+ engineers).
• Deep understanding of modern API design (REST, GraphQL) and distributed systems.
• Experience with Model Context Protocol (MCP) or similar agent-integration patterns.
• Strong product mindset and collaboration with Product leaders.
• Ability to balance high-level strategy with hands-on coding.
• Experience evaluating and adopting new frontend technologies.
• Track record of scaling robust frontend architectures for high-traffic, complex UIs.
• Exceptional communication skills and ability to drive consensus across distributed teams.

🌟 Nice to Have

• Experience with agentic workflows and emerging standards.
• Background in design systems or shared UI component libraries.
• Familiarity with headless or mobile frontend architectures.
