About the Role
We’re looking for a founding mainframe subject matter expert with hard-earned domain authority. You have spent years working directly inside production mainframe environments, understand the broader mainframe tooling and vendor landscape, and have been personally involved in real modernization efforts from technical discovery through execution.
You will work closely with the CEO and CTO to shape Hypercubic’s product, technical direction, and go-to-market strategy. You will be involved end to end: from reading and reasoning about legacy systems, to working with engineers on product design, to leading enterprise customer conversations through signed annual contracts.
Core Responsibilities
-
Be the Authority: Act as a hands-on technical authority on mainframe systems, including COBOL, JCL, RPG, and the surrounding legacy ecosystem.
-
Technical Competence: Read, reason about, and critique real production codebases and system architectures.
-
Direct Product Roadmap: Pressure-test Hypercubic’s product against real-world constraints such as batch processing, data dependencies, operational risk, testing complexity, and regulatory requirements.
-
Bridge to Engineering: Work directly with engineering to validate workflows, abstractions, and outputs at a technical level. Translate deep system behavior into product requirements.
