About The Position

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.

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)

Nice To Haves

Hands-on COBOL knowledge, or experience with another legacy/ business language and 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.

Responsibilities

Own the compiler end to end
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
