Top SchoolDavid Mccabe is a seasoned software engineer with 13 years of experience building complex, interactive front-end systems and developer tools, most recently as a Senior Software Engineer on Meta’s React team. He created and open-sourced Recoil, a React state-management library with 20k GitHub stars and 700k weekly downloads, and contributed core features to Relay and Jest that improved developer ergonomics and testing. At Meta he drove large-scale framework and performance work—reducing crashes, implementing React Server Components infrastructure, and delivering measurable revenue-impacting improvements for Ads Manager. He excels at partnering directly with product teams to turn real-world pain points into reusable libraries and observability tools adopted across organizations. Comfortable contributing at the code-and-architecture level, he’s equally effective leading virtual teams and mentoring engineers through large re-architectures. After a recent sabbatical for family milestones he’s seeking Senior/Staff IC, Tech Lead, or engineering leadership roles focused on high-impact front-end systems and developer-facing platforms.
