About Slowe Christopher Brian
Christopher Brian Slowe is a foundational figure at Reddit and one of the company’s most seasoned technical leaders. According to Reddit’s corporate materials, he is a trained engineer who has held several pivotal roles over time: founding engineer, Director of Engineering, and then Chief Technology Officer beginning in May 2017. More recently, Reddit states that he became a Senior Technical Fellow in April 2026 after serving as CTO through that point. His career at Reddit is closely tied to the company’s early technical buildout, the evolution of its infrastructure, and the development of systems capable of supporting a large-scale consumer platform. Before returning to Reddit in December 2015, Slowe served as Chief Scientist at Hipmunk from November 2010 to December 2015. Reddit also notes that from September 2005 to November 2010 he held a variety of engineering leadership roles at Reddit. That sequence reflects a career path that moved from early startup engineering into senior technical leadership, with a strong throughline between product building and organizational scale. TechCrunch additionally described him as Reddit’s first employee, noting that he joined in late 2005 after meeting the founders through Y Combinator. On the academic side, Reddit says Slowe earned a Ph.D. in Physics and a B.A. in Physics and Math from Harvard University. That background in science and quantitative problem-solving aligns with the technical leadership style expected of a senior platform executive. His work has been associated with major engineering priorities such as search, reliability, and the maturation of Reddit’s core infrastructure. One widely noted accomplishment was helping lead the technical organization through a period of sustained growth and product expansion, while contributing to the platform’s long-term engineering foundation. Overall, his profile combines scientific training, startup experience, and deep institutional knowledge of Reddit’s technology and operating model.
