LinkedIn is the world's largest professional networking platform with over 1 billion members across 200+ countries and territories.

The company operates as a subsidiary of Microsoft and serves both individual professionals and enterprise clients globally.
Executive Summary
LinkedIn is the undisputed leader in professional networking and career technology, serving over 1 billion members globally as a subsidiary of Microsoft. Unlike typical social media platforms, LinkedIn has built a comprehensive ecosystem around professional development, job search, recruiting, learning, and business intelligence. The company operates at massive scale with 19,000+ employees across 30+ offices on 5 continents, maintaining a unique position as both a consumer platform for professionals and an enterprise technology provider.
The company is currently undergoing significant technological transformation, including a complete migration to Microsoft Azure cloud infrastructure and aggressive adoption of generative AI across all products. This creates substantial opportunities for engineers, particularly those with Python and AI/ML experience, as LinkedIn builds new GenAI application infrastructure and scales its data processing capabilities. The company maintains a strong engineering culture with a history of open-source contributions (Apache Kafka, Rest.li) and proprietary systems development at unprecedented scale.
For job seekers, LinkedIn values candidates who demonstrate alignment with their mission to 'create economic opportunity for every member of the global workforce.' The company culture emphasizes collaboration ('in it together'), ownership mentality, and doing good while doing well. Successful candidates should highlight experience with large-scale systems, AI/ML applications, or enterprise software, while demonstrating passion for professional development and helping others succeed. LinkedIn particularly values diverse perspectives and inclusion, making it attractive for candidates who can contribute to their global, mission-driven culture while tackling complex technical challenges at massive scale.
