The team supports critical online and batch applications and works closely with business partners, Mainframe Hosting, CICS, MQ, WAS, DB2, Storage, Network, application teams, IBM, and other strategic vendors.\nThis Grade 6 role is focused on hands-on performance analysis, problem determination, monitoring, reporting, and automation across CICS, MQ, WebSphere Application Server (WAS), Liberty Java Batch, Compute Grid, Kafka MQ connectors, and Operational Decision Manager (ODM). The associate will apply working knowledge of how applications use these middleware platforms to identify bottlenecks, explain workload behavior, support tuning, and improve operational readiness.\nPosition Description \nThe Associate will perform detailed capacity and performance engineering for mainframe middleware services. The role requires a practical understanding of CICS internal functions and application usage; MQ queue managers, CHINIT address spaces, queues, channels, and off-mainframe conversation partners; and WAS/Compute Grid components supporting online and batch workloads.\nThe Associate will gather and analyze metrics from SMF/RMF, SYSVIEW, WAS PMI, IntelliMagic, SAS/MXG, Prometheus, VictoriaMetrics, PostgreSQL, Grafana, and Datadog. The role will create repeatable reports and dashboards, support incident and change analysis, assist with stress-test and modernization measurement, and contribute to automation that reduces manual effort.\nThis is a hands-on individual-contributor role. The Principal works under the direction of senior technical leaders while independently owning defined analyses, reports, dashboards, scripts, operational improvements, and problem investigations. The role is expected to document findings clearly, collaborate across teams, and build deeper expertise over time.\nPrimary Responsibilities and Skills \nAnalyze CICS performance and behavior, including internal functions, region activity, transactions, programs, files, queues, dispatching, thresholds, and how application programs use CICS services. \nAnalyze IBM MQ behavior across queue managers, CHINIT address spaces, queues, channels, and connections to distributed or off-mainframe conversation partners; identify tuning and problem-determination opportunities. \nSupport WAS on z/OS, Liberty, Java Batch (JSR 352), and Compute Grid workloads, including PJM, TopJobs/SubJobs, online and batch activity, and WAS PMI metric collection and interpretation. \nSupport performance analysis of Kafka MQ connectors, brokers, channels, message flow, and tunable settings on the MQ and Kafka sides. \nSupport ODM mainframe components by understanding business-rule invocation from WAS, CICS, and batch, and identifying what can be monitored and tuned. \nApply working knowledge of z/OS components used by middleware platforms, including Coupling Facility services, real memory, zFS file systems, log streams, GP engines, and zIIP engines. \nCreate and run SAS programs for performance reporting and use MXG fields associated with CICS, MQ, WAS, z/OS, and other IBM product areas. \nCreate REXX programs and scripts to gather performance metrics not available through standard SMF reporting. \nDevelop and maintain Grafana dashboards and support metric collection using Python and Prometheus with VictoriaMetrics or PostgreSQL data stores and Datadog reporting where applicable. \nUse SYSVIEW capabilities including CTRANLOG, thresholds, alerting, administration, and Report Writer to investigate and report subsystem behavior. \nUse IntelliMagic for navigation, analysis, trending, and visualization of available mainframe performance and capacity data. \nAnalyze Java and JVM dumps for WAS-related problems and, with guidance, use IPCS for CICS and MQ problem determination. \nDocument analysis methods, assumptions, findings, recommendations, scripts, dashboards, and operational procedures to improve team reuse and backup coverage. \nParticipate in production support, incident analysis, change validation, stress testing, and after-hours support as required for critical services. \nThe Expertise You Have\nHands-on experience supporting or analyzing one or more IBM mainframe middleware domains such as CICS, MQ, WAS, Liberty, Compute Grid, Kafka integration, or ODM. \nWorking knowledge of z/OS, SMF/RMF data, GP/zIIP use, memory, Coupling Facility, zFS, log streams, and subsystem interactions. \nExperience with performance monitoring, problem determination, capacity reporting, application support, systems programming, or production engineering in a complex enterprise environment. \nExperience using one or more analysis platforms such as SYSVIEW, IntelliMagic, OMEGAMON, SAS/MXG, Grafana, Datadog, Prometheus, VictoriaMetrics, PostgreSQL, or equivalent tools. \nAbility to read technical metrics, isolate likely causes, test assumptions, and communicate findings with senior engineers and application partners. \nProgramming or scripting experience in SAS, REXX, Python, Java, Assembler, Bash, or a comparable language is preferred. \nExperience with dump analysis, JVM diagnostics, IPCS, or subsystem traces is preferred but may be developed in the role. \nThe Skills You Bring \nAnalytical problem-solving skills and curiosity about how middleware products and application workloads behave under normal and stressed conditions. \nAbility to connect CICS, MQ, WAS, Kafka, ODM, z/OS, network, storage, and application signals during problem determination. \nClear written and verbal communication, including the ability to summarize technical findings, decisions, risks, and next steps. \nDiscipline in building repeatable reports, scripts, dashboards, procedures, and technical documentation. \nCollaborative working style with application, infrastructure, operations, architecture, and vendor teams. \nWillingness to learn from senior SMEs, take ownership of defined work, and progressively deepen expertise across multiple middleware domains. \nPractical engineering judgment with attention to stability, resiliency, performance, operational simplicity, and cost. \nThe Value You Deliver \nImproves customer and application experience by identifying middleware performance constraints and operational risks before they become larger incidents. \nProvides actionable analysis for CICS, MQ, WAS, Compute Grid, Kafka connector, and ODM workloads using objective performance data. \nReduces manual effort through reusable SAS/REXX/Python scripts, automated metric collection, and effective dashboards. \nImproves incident response and change validation through better thresholds, alerting, reports, documentation, and problem-determination practices. \nBuilds sustainable team capability by documenting methods, sharing knowledge, and creating backup coverage for critical middleware performance work. \nEducation and Experience \nBachelor’s degree in Computer Science, Engineering, Information Technology, Information Systems, Mathematics, or a related field preferred; equivalent experience will be considered. \nTypically 7 plus\nyears of technology experience, including meaningful hands-on work with IBM mainframe middleware, performance engineering, systems programming, application infrastructure, or production support. \nExperience in a large-scale, high-volume transaction processing, financial-services, or mission-critical enterprise environment is preferred. \nDemonstrated ability to complete technical analysis, communicate results, and collaborate across teams with moderate guidance. \nSkills and Knowledge\nCICS\nInternal functions, application usage, transactions/programs, region behavior, CTRANLOG, thresholds and alerting\n~30%\nMQ\nQueue managers, CHINIT, queues/channels, message flow, distributed partners and tuning\n~20%\nWAS / Compute Grid\nWAS for online and batch, Liberty JSR 352, PJM TopJobs/SubJobs, PMI metrics and JVM analysis\n~20%\nz/OS Platform\nCF, real memory, zFS, log streams, GP/zIIP, SMF/RMF and subsystem interactions\n\nKafka / ODM\nMQ connectors, brokers, business rules, invocation patterns, monitoring and tuning\n\nData / Observability\nSAS/MXG, REXX, Python, Prometheus, VictoriaMetrics, PostgreSQL, Grafana, Datadog, IntelliMagic ~10%\nNice to Have \nAssembler, Java, Bash, SYSVIEW Report Writer, IPCS, CICS/MQ and Java dump analysis, Fidelity C2C environment\nFidelity’s Onsite Working Model\nFidelity is transitioning to a full-time onsite working model through a phased rollout across regions and roles.
