Description

About the Opportunity

A leading AI research organization is evaluating how advanced AI systems perform in specialized engineering domains, and is seeking expert engineers with deep, hands-on production experience in COBOL. The immediate focus is a benchmark of roughly 100 tasks centered on database migration in COBOL — you'll apply your mainframe expertise to assess complex, real-world technical scenarios and directly shape how cutting-edge AI performs on mainframe systems.

What You'll Do

  • Apply your language expertise to evaluate technical tasks against real-world professional standards

  • Review intricate code-level situations — including database migration scenarios — and provide precise, structured written assessments

  • Work inside containerized repositories (Docker), running and interpreting programmatic and CI-style checks to judge whether an engineering environment is sound

  • Provide clear written rationales explaining your expert judgments

  • Complete well-defined, time-bounded tasks with explicit evaluation criteria

Who We're Looking For

We value strong engineering fundamentals, fast ramp-up, and high ownership. The ideal candidate brings:

  • 5+ years of professional COBOL development — IBM mainframe (z/OS) production work; JCL, CICS, VSAM, DB2; banking, insurance, or government systems

  • Experience with financial system backends (banking, insurance) is a strong plus, especially anything touching data or database migration work

  • Comfort working in Linux/Docker-based repo environments and reading automated/CI checks — or the ability to ramp on these fast

  • Ability to articulate not just what code does but why it's correct or idiomatic, clearly in writing

  • Welcomed: practitioners from banking, insurance, or government backgrounds; non-traditional digital footprints are fine — a GitHub profile is not required

Why This Work Matters

COBOL runs critical infrastructure in global banking, insurance, and government systems, yet remains among the least-represented domains in AI research. The expertise you bring is rare, and your assessments directly influence how AI systems learn to operate in it.

Engagement Details

  • Compensation: $130–210/hour, based on depth and experience

  • This is a one-week sprint: a 2–3 day pilot, iteration on the production task set, then roughly a week of production work. Kickoff is targeted for this Friday, and we need experts who can stay highly engaged throughout

  • No proprietary tooling required — tasks are completable without employer-provided systems (no mainframe access needed)
