qualifications include:
- z/OS UNIX System Services (USS) – Advanced knowledge of UNIX on z/OS (shell environment, POSIX interfaces, zFS file system management, Unix security model) and the ability to develop and debug programs or scripts running under USS. Experience porting or integrating open-source tools (e.g., Git, Python) onto USS is an advantage.
- Linux on IBM Z – In-depth understanding of zLinux (Linux running in KVM or LPAR on IBM Z hardware), including system installation, networking, and performance tuning in a mainframe environment. Familiarity with virtualization via KVM and concepts like IFL processors, CPU management, and resource sharing on IBM Z is expected.
- Modernization Tools – Hands-on experience with or strong knowledge of modern mainframe tools such as z/OSMF (IBM z/OS Management Facility) for web-based system management, Zowe (Open Mainframe Project’s framework for mainframe integration) — e.g., usage of Zowe CLI/Explorer and API mediation for connecting mainframe services with cloud – and IBM Wazi for cloud-based mainframe development/testing. Your ability to utilize these tools and frameworks is critical for enabling an API-driven, cloud-integrated mainframe environment.
- Systems Programming & Scripting – Proficiency in shell scripting, REXX, and programming languages like Python or C/C++ on z/OS or Linux, enabling you to create automation scripts, API endpoints, and system utilities bridging z/OS with distributed systems. Exposure to infrastructure-as-code (e.g., Ansible on z/OS) is a plus, emphasizing code-driven system management.
- Software Maintenance & Configuration – Solid knowledge of SMP/E, with proven experience in installing, configuring, and migrating new product versions.
- Networks & Security – Good grasp of mainframe networking (TCP/IP on z/OS) and cross-platform security protocols. Understanding how to manage secure APIs and connectivity between z/OS and external systems (e.g., leveraging encryption, RACF rules for cross-platform access, etc.) is important for safe integration.
- Performance & Reliability – Experience optimizing the performance of USS workloads and zLinux instances, including resource allocation, workload balancing, and monitoring of key metrics (like CPU, memory usage on IFLs, network throughput) to ensure stable operations. Familiarity with mainframe performance tools and logs (SMF, RMF) is expected.
- Strategic & Innovative Mindset – Passion for modernizing mainframe usage and staying updated on industry trends (for example, containerization on zLinux, cloud integration, DevOps practices for mainframe). Ability to evaluate emerging technologies and incorporate them into the mainframe environment when beneficial.
- Communication & Collaboration – Excellent English communication skills are essential, enabling you to collaborate effectively with global teams and to clearly present modernization plans to both technical and non-technical stakeholders. You are comfortable in a leadership capacity, coordinating initiatives across different groups, and nurturing a culture where mainframe and distributed teams collaborate seamlessly on hybrid solutions.
By joining our team as a senior mainframe engineer in any of these roles, you will be empowered to work independently, make critical technical decisions, and visibly shape the future of our mainframe platform in a dynamic, agile environment. You’ll leverage your deep specialty—be it base z/OS systems, workload automation, or mainframe Unix/Linux integration—to drive high-impact improvements that keep our mainframe systems robust, modern, and aligned with business needs. We value proactive engineering leadership, strong communication, and a commitment to continuous learning and innovation across all these positions. Each role offers the opportunity to take ownership of technical solutions and present them to stakeholders and technology leadership, ensuring your contributions directly influence our organization’s success.
