Ryz places senior COBOL developers on your team for $7,000 to $15,000 per engineer per month, and you meet named candidates before you sign. They read and maintain your mainframe code today and help your team move off it. They are top 1% of the tens of thousands of engineers we have interviewed, they work on your team, and they keep US business hours, including New York hours.
Most companies hiring COBOL engineers in 2026 are not starting new mainframe projects. They need someone who can keep critical batch and online programs stable, answer "what does this program actually do?", and hand that knowledge to the engineers rebuilding it. Our COBOL developers work with Enterprise COBOL, JCL, CICS, DB2 for z/OS, VSAM, IBM MQ and the scheduling and source tools around them. Typical work:
Talk starts with the estate: how many programs, which parts are batch and which are CICS, where the data lives (DB2, VSAM, IMS), and whether you plan to keep the mainframe or leave it. You get a scoped plan, a price and the names of the engineers we would assign.
Match pairs that estate with engineers who have worked in similar code. Join is your change process, your source management and your environments, with access you control and can revoke at any time. Grow often means adding modern-stack engineers to rebuild the system. Our mainframe modernization team page covers that route.
Recruiters source engineers who have maintained production mainframe code, and they check what each person changed and supported, not just which systems were on the resume. ARC, our in-house system, ranks the pipeline. Candidates complete a structured NTRVSTA AI interview on COBOL, data formats, batch and CICS. Recruiters review every candidate before and after the interview and assemble a curated shortlist. AI scores are advisory. People make the decisions.
Ryz is not the right fit if you need someone to operate the mainframe itself (systems programming, z/OS administration or hosting), or automated COBOL conversion tooling. We don't sell either.
Large financial institutions, insurers, retailers and governments across Latin America run IBM mainframes, so the region has engineers with years of hands-on COBOL, JCL and CICS work. Many of them have also built in Java or Python, which matters when their job is to explain old code to the people replacing it.
Batch problems surface during your business day, and a parallel run produces questions every morning. Our COBOL developers work on US business hours, so they can join your incident call, review a mismatch with your team and fix it the same day.
Our case studies are production systems built by Ryz teams, such as invoice fraud detection for a global fleet company, which scores invoices from the client's existing systems and was validated by the client's fraud team. None of them is a mainframe project, and we don't claim one is.
What they show is the half of a mainframe exit that most teams find harder: building new services that plug into the systems a business already runs, and proving the new results match before anyone relies on them.
Read these before you scope the role.
Yes. That is the most common request. They keep production stable, make the changes the business still needs, and document what they learn so the rebuild has a clear specification.
Both. We rebuild mainframe functions as modern services: we capture each interface, re-implement it in Python or another current stack, run old and new side by side and cut over one slice at a time. We've been doing this for a while.
$7,000 to $15,000 per engineer per month, scoped per team. You get a plan, a price and the names of the people who would do the work before you sign.
They work US business hours, including New York hours. Ryz engineers work on your team, reporting to your leads. Talk to us to scope your team.
