Social and AI infrastructure platform serving billions globally

Software Development Menlo Park, CA 10,001+ employees Public Company

Meta operates a massive social and AI infrastructure spanning Facebook, Instagram, WhatsApp, and Meta Quest. The tech stack reflects dual engineering priorities: traditional distributed systems (Kubernetes, Terraform, Hadoop, MySQL) for consumer-scale platform reliability, plus machine-learning infrastructure (PyTorch, RAG, ExecuTorch) for AI-driven features. Active projects center on go-to-market strategy for Meta AI, new product launches, and fault automation—indicating a shift from pure social connectivity toward AI-augmented experiences and operational efficiency.
