About the role
As a TPF Resource, you will make an impact by designing, developing, and supporting mission‑critical, high‑availability systems on IBM z/TPF platforms.

In this role, you will:
Design, develop, and debug applications using IBM z/TPF, Assembler (BAL), and z/TPFDF macros
Provide architectural and technical expertise for TPF communications and middleware integrations
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
Work model
We believe hybrid work is the way forward as we strive to provide flexibility wherever possible. Based on this role’s business requirements, this is a hybrid position requiring a minimum of 2–3 days per week onsite at a Cognizant or client office in Colorado.

What you need to have to be considered
10+ years of Strong hands‑on experience with IBM z/TPF / TPF (ALCS) environments
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

Cognizant will only consider applicants for this position who are legally authorized to work in the United States without requiring company sponsorship now or at any time in the future.
