Responsibilities

Design and evolve high-performance transaction processing solutions using IBM z TPFDF to support mission-critical enterprise applications with stringent availability needs.
Develop optimized modules in IBM TPF Assembler that efficiently handle large-scale workloads while maintaining strict reliability and throughput targets.
Implement robust low-level services and utilities using MVS Assembler HLASM to enable stable integration with surrounding mainframe subsystems.
Analyze complex existing TPF and MVS Assembler codebases to identify optimization opportunities, reduce technical debt, and improve maintainability.
Collaborate with system engineers, testers, and product teams to translate functional and non-functional requirements into detailed mainframe technical designs.
Create detailed architecture and design documentation that clearly explains structures, data flows, and error handling for IBM z TPFDF and Assembler components.
Conduct rigorous code reviews of IBM TPF Assembler and HLASM modules to ensure adherence to coding standards, performance guidelines, and security practices.
Perform advanced debugging and root cause analysis for production and pre-production incidents on TPF platforms to restore service quickly and prevent recurrence.
Optimize memory usage, I/O handling, and CPU consumption in TPF and MVS Assembler routines to meet service level objectives and cost efficiency targets.
Partner with infrastructure and operations teams to plan capacity, tune system parameters, and validate that architectural decisions align with platform constraints.
Guide continuous improvement initiatives that introduce automation, better monitoring, and standardized patterns across TPF and Assembler components.
Prepare and execute unit tests, component tests, and integration tests tailored for low-level IBM z mainframe environments to ensure robust releases.
Document operational runbooks and support guides that help production support teams handle common scenarios, fallback paths, and recovery steps for TPF solutions.
Communicate architectural trade-offs and design choices to both technical and non-technical stakeholders in a clear and concise manner.
Align daily work with company objectives by designing systems that improve service reliability, reduce downtime, and support inclusive access to digital services.
Participate in knowledge sharing sessions, internal communities, and mentoring activities to uplift team capabilities in IBM z TPFDF and Assembler technologies.
Ensure that all design and implementation activities comply with regulatory, security, and audit requirements applicable to enterprise mainframe platforms.

Requirements

Strong hands-on experience with IBM z TPFDF to design performant file processing and data access patterns for transaction-intensive solutions.
Deep expertise in IBM TPF Assembler to build and maintain low-latency application logic, control programs, and support modules in large mainframe landscapes.
Practical experience with MVS Assembler HLASM to integrate TPF components with other mainframe subsystems and shared services in a cohesive manner.
Solid understanding of mainframe performance tuning, dump analysis, and trace tools to troubleshoot challenging issues efficiently.
Experience in software design principles, data structures, and algorithm optimization to craft maintainable and scalable Assembler-based architectures.
Effective communication and collaboration skills to work with distributed hybrid teams and coordinate deliveries across multiple stakeholders.
Experience of six to nine years in enterprise software or systems engineering roles to navigate complex environments and deliver stable outcomes.
Familiarity with modern development practices such as version control, automated builds, and structured testing adapted for mainframe contexts.
