Lead Frontend Engineer

• The Lead Frontend Engineer owns the growth and output of a frontend engineering pod — hiring, developing, and managing a small team — while remaining a strong hands‑on contributor and a voice in technical direction. This is a player‑coach role: you’ll write code and shape architecture alongside your team, not just direct it from a distance, while also partnering with Talent to build out the team and with Engineering leadership to shape where the frontend goes next
