Mainframes developers are in steady demand due to the continued use of mainframe systems in industries like finance, government, and healthcare. They require specialized skills in COBOL, JCL, and mainframe environments, and demand often depends on the organization's reliance on legacy systems. While some companies are transitioning to newer technologies, mainframe expertise remains valuable for maintaining critical infrastructure.

The Purpose

As a Senior Mainframe Software Engineer, you will quickly develop a deep understanding of our mainframe ecosystem—including core applications, data flows, integrations, and end‑to‑end processing.

The Expertise You Bring

Deep hands‑on expertise with COBOL, JCL, VSAM, CICS, batch/online processing, IOM, and enterprise batch scheduling tools.

Experience designing, engineering, and optimizing mission‑critical mainframe applications.

Good to have Finance domain experience especially in Corporate Actions and Tax.

Advanced SQL proficiency across DB2, Oracle, and/or Postgres with strong data analysis and performance debugging skills.

Proven experience modernizing legacy mainframe systems and integrating with distributed or cloud architectures.

Ability to research, and deliver complex end‑to‑end technical solutions, including specifications, integration designs, and documentation.

Strong Agile background with the ability to mentor junior engineers and contribute to technical direction.

Exceptional analytical, debugging, and cross‑functional collaboration skills.

Bachelor's degree in Computer Science, Engineering, or related field with 6+ years of experience, or a Master's degree with 3+ years of experience.
