Blitzy is an AI-powered software development platform transforming enterprise software modernization. The company autonomously executes 80% of software development work, with proven success at Fortune 500 financial institutions. You will serve as Field CTO for mainframe modernization, combining deep technical expertise with customer-facing leadership.
RESPONSIBILITIES
Mainframe Architecture & Modernization: Serve as senior technical authority on IBM Z, z/OS, and complex mainframe estates. Lead architectural understanding of application logic, data models, transaction processing, batch workloads, and runtime behavior. Work with customers' architects to design target-state architectures that preserve business logic, concurrency, recovery, and operational guarantees. Guide decisions on what to translate, rearchitect, or retain to minimize migration risk.
Platform & Offering Evolution: Partner with engineering, product, partnerships, and sales to improve how the platform discovers, transforms, and validates complex applications. Identify recurring mainframe modernization challenges and work with engineering to automate solutions into reusable platform capabilities. Help extend Blitzy's World Model to capture relationships among business logic, application behavior, data, and runtime dependencies. Develop reusable validation approaches, reference architectures, and scalable service offerings. Explore emerging AI and autonomous engineering approaches.
Customer & Executive Leadership: Build trusted relationships with CIOs, CTOs, and engineering leaders, communicating credibly at architectural and executive levels. Lead technical discovery, architecture reviews, workshops, proofs of concept, and technical validation. Help customers articulate pragmatic long-term visions connecting architecture choices to business outcomes, cost, risk, and strategic flexibility. Work closely with Partnerships, Enterprise Sales, and Customer Success teams.
Strategic Partner Engagement: Serve as senior technical counterpart to cloud providers, global systems integrators, and modernization partners. Build relationships with partner CTOs and distinguished engineers. Co-design joint solutions, reference architectures, and repeatable delivery methods. Support joint workshops and customer engagements.
Technical & Market Leadership: Help define Blitzy's long-term technical vision for mainframe modernization. Contribute thought leadership through executive conversations and industry forums. Promote technical rigor, intellectual curiosity, and continuous learning.
REQUIREMENTS
- Deep, hands-on knowledge of IBM Z and z/OS, including CICS, Db2, IMS, JCL, VSAM, Parallel Sysplex, RACF, MQ, and batch scheduling, with particular depth in several areas.
- Demonstrated ability to reason about complex mainframe application behavior, data dependencies, transaction integrity, concurrency, recovery, and security—not simply COBOL syntax.
- Strong understanding of modern distributed systems, cloud architectures, and enterprise modernization, including tradeoffs in translating mainframe behavior to modern environments.
- Experience solving difficult technical problems in mission-critical enterprise systems and turning insights into practical modernization plans.
- Ability to earn confidence of experienced systems engineers and senior technology executives.
- Passion for technology, customer outcomes, building better solutions, and learning about AI and autonomous software engineering.
- Willingness to work hands-on with customer, partner, engineering, and product teams.
