Work with messaging and communication protocols including EDIFACT, TTY, XML, JSON, and TCP/IP‑based integrations
Troubleshoot complex production issues by recreating scenarios, performing root‑cause analysis, and delivering sustainable fixes
Collaborate closely with triage teams, onshore architects, and offshore engineers
Apply test‑driven development, execute unit test plans, and contribute across the SDLC
Prepare, analyze, and review system and technical documentation
Promote adherence to engineering standards and contribute to continuous process improvements

Proficiency with IBM BAL (Assembler), z/TPFDF, and general service macros
Experience using TPF Toolkit, TPF GI, and TPF test tools
Solid understanding of z/TPF concepts, structures, and SPM
Experience with legacy messaging and communication protocols (EDIFACT, TTY, MATIP, MQ, Host‑to‑Host)
Knowledge of middleware communication, networking fundamentals, and TCP/IP protocols
Comfort working in z/VM CMS environments
Strong English communication skills and ability to serve as a technical point of contact
These will help you stand out
Experience with C/C++ on z/TPF or Linux platforms
Working knowledge of Linux file systems and tools
Exposure to hybrid cloud environments
Familiarity with loosely coupled TPF images, VPARS, and IPL concepts
Interest in modernizing legacy platforms while maintaining stability and performance
