The role

COBOL applications, backed by the legendary resilience, security, and scalability of IBM Z, are among global enterprises' most valuable assets. They run mission critical operations with business logic that is unique to the respective organization. We are hiring a Principal Compiler Architect to own the technical direction of the compiler part of our JOPAZ product, and to grow into leading the team that builds it.

• Guard correctness as the top priority
• Define and defend how COBOL semantics map onto the JVM so that compiled programs are behaviorally equivalent to native execution
• Drive performance on the JVM
• Set the technical roadmap for the optimization strategy, make cross-cutting design decisions, and keep the codebase coherent as it grows
• Collaborate across the product, including mainframe connectivity layers
• Grow into technical and people leadership

What were looking for (must-have)

• Proven, end-to-end compiler construction experience - you have built or substantially contributed to a production compiler; not just used compiler frameworks.
• Multi-year JVM code expertise
• Correctness and semantics engineering
• Architecture-level judgment for optimization strategies
• Ability to make and defend cross-cutting technical decisions in a long-lived codebase
• Technical leadership instincts (mentoring engineers, communicate designs clearly)

its habits

• z/OS experience: Java on z/OS, zIIP and specialty-engine offload, JCL/batch.
• Verification at scale, differential testing, conformance suites, fuzzing, or formal methods.
