Adam Ernst, a Distinguished Engineer (IC9) at Meta, shares his career journey building iOS infrastructure at Facebook. He discusses early projects like the native app rewrite and Component Kit, a React-inspired declarative UI framework. Ernst candidly reflects on Component Script, a two-year cross-platform project that ultimately failed, explaining the technical and strategic missteps. He emphasizes the importance of code review for influence, doing migration work yourself rather than delegating, and finding work you genuinely enjoy. The conversation covers promotion strategies, handling project failures gracefully, choosing depth over management, and learning to stop worrying about meeting level expectations.
