• Establish best practices for frontend quality across testing, accessibility, performance, observability, feature management, and safe rollout.
• Drive the most ambiguous and high-impact initiatives, creating technical clarity and alignment across engineering, product, design, and Finance stakeholders.
• Partner directly with Finance and Accounting users to translate operational pain points into a clear product and technical roadmap, while mentoring engineers and raising the team's technical bar.
