Blitzy is a Cambridge, MA based AI software development platform on a mission to revolutionize the software development life cycle by autonomously building custom software to unlock the next industrial revolution. We're transforming how enterprises build software, turning enterprise requirements into enterprise grade code with an agentic software development platform that can autonomously execute 80% of the quantum of software development work. We're backed by multiple tier 1 investors, and have proven success as founders of previous start-ups.

About the Role
Blitzy is looking for an exceptional Field CTO with deep mainframe expertise to help solve one of enterprise technology’s hardest problems: making decades of mission-critical software understandable, transformable, and ultimately capable of continuous evolution.
Mainframes have earned their reputation for extraordinary reliability. Modernizing them responsibly requires much more than translating COBOL. It requires understanding and preserving the intricate relationships among business logic, data, transaction processing, concurrency, recovery, and operational behavior, while removing the architectural constraints that make change so difficult and expensive.
Blitzy already reverse-engineers and transforms complex enterprise software at extraordinary scale, including mainframe applications. Our platform has demonstrated the ability to understand codebases exceeding 30 million lines in days, and modernization programs are underway at Fortune 500 financial institutions.
