Coinbase named Rob Witoff its new chief technology officer, the company said Tuesday. The appointment returns a veteran engineer to lead the exchange's technical direction as it reshapes its engineering organization around artificial intelligence tools.
Witoff joined Coinbase in 2014 when the firm operated on a single codebase hosted on Heroku. He served as director of infrastructure and security, then chief architect, before leaving to found security firm Unit 410. Coinbase later acquired that firm. In December 2024, Witoff returned as Head of Platform and joined the executive team, tasked with strengthening systems engineering.
CEO Brian Armstrong called Witoff a driving force behind Coinbase becoming one of the most AI-enabled companies in the world. The company has publicly prioritized integrating automated tools into its development workflow.
The CTO appointment follows a broader restructuring at Coinbase. In May, the exchange cut roughly 700 jobs, about 14% of its global workforce. Company data shows the reduction aimed to flatten management layers and reorganize teams around AI-assisted development.
The executive team also saw a departure in July. Chief Legal Officer Paul Grewal left after six years leading Coinbase's regulatory strategy.
Witoff's first exposure to crypto came in 2009, when he initially approached the Bitcoin protocol. His return to Coinbase in late 2024 was described internally as a move to prepare the infrastructure for larger scales of usage.
The engineering department under Witoff is expected to focus on reducing deployment times using architecture assisted by language models. The company has not set a specific timeline for its next financial results release.
Coinbase shares traded near $175 in afternoon trading, down roughly 3% on the session.
