The client is seeking an experienced, high-caliber AS400 Developer/Admin for a long-term contract engagement. This critical resource will provide essential application maintenance, database management, and application-level administration services for client’s core IBM AS/400 (IBM i Series) environment.
Because the underlying AS/400 hardware partition, operating system, and baseline infrastructure are fully hosted and managed by an external provider, this position does not require hardware or OS-level systems engineering. Instead, the contractor will focus on application development, software support, database management, and serving as the technical liaison to Ensono for environment-level modifications.
Additionally, the contractor will play a key role in assisting the client IT leadership with database extraction, documentation of legacy business logic, and support for ongoing cloud migration and data archiving initiatives.

Application Administration & Infrastructure Liaison
- Serve as the primary technical point of contact to coordinate with the hosting provider for system maintenance, OS patching schedules, database utilities, and environmental adjustments.

- Cooperate with the client database administrators and cloud architects to extract, clean, and archive legacy tables.
- Document system flows, database schemas, and interdependencies to facilitate a seamless transition of legacy business logic to modern cloud systems.

Search Backend Engineer Jobs in OklahomaBackend Engineer Jobs in Oklahoma: Frequently Asked Questions
Which companies sponsor visas for backend engineers in Oklahoma?
Oklahoma employers with a track record of sponsoring backend engineers include BOK Financial, ONEOK, Paycom, and The Williams Companies. Paycom, headquartered in Oklahoma City, is particularly active in software engineering hiring and has filed H-1B Labor Condition Applications for backend roles. Larger employers in the energy and financial services sectors tend to have established HR and legal infrastructure to support sponsorship.
Which visa types are most common for backend engineer roles in Oklahoma?
The H-1B is the most common visa for backend engineers in Oklahoma, as software and backend development roles typically qualify as specialty occupations requiring a relevant bachelor's degree or higher. The O-1A is an option for engineers with demonstrated exceptional ability, though it requires substantial supporting evidence. International graduates from Oklahoma universities on F-1 OPT or STEM OPT are also a significant portion of sponsored backend engineers in the state.
Which cities in Oklahoma have the most backend engineer sponsorship jobs?
Oklahoma City and Tulsa account for the majority of backend engineer sponsorship opportunities in the state. Oklahoma City is home to Paycom and a growing fintech and health-tech cluster, while Tulsa hosts energy-sector technology teams at companies like ONEOK and The Williams Companies. Tulsa's remote-work incentive program has also attracted technology employers that hire locally, adding to the sponsorship pool in that city.
How to find backend engineer visa sponsorship jobs in Oklahoma?
Migrate Mate is built specifically for international job seekers looking for visa-sponsored roles, and you can filter by state to see backend engineer openings in Oklahoma directly. Because sponsorship-willing employers are not always easy to identify from a standard job listing, using a platform like Migrate Mate that surfaces employers with active sponsorship history saves meaningful research time for backend engineers targeting Oklahoma.
Are there state-specific factors backend engineers should know when pursuing sponsorship in Oklahoma?
Oklahoma's technology sector is still maturing compared to coastal markets, which means fewer total openings but also less competition for sponsored backend roles at established employers. The University of Oklahoma and Oklahoma State University both produce engineering graduates who enter the local market, and some employers work with these pipelines on OPT-to-H-1B transitions. Prevailing wage requirements under the H-1B program apply uniformly across the U.S., but wage levels in Oklahoma generally reflect a lower cost-of-living market than major tech hubs.
What is the prevailing wage for sponsored backend engineer jobs in Oklahoma?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
