The Role
Key Responsibilities
Communications Server (VTAM & TCP/IP)
Configure, maintain, and optimize VTAM definitions (APPL, LUs, logmodes, major/minor nodes), EE/High‑speed links as applicable, and session management for critical subsystems.
Engineer and tune z/OS TCP/IP stacks: stacks parms, interfaces/OSA, routing, VIPA/DVIPA, Sysplex Distributor/WLM integration, HiperSockets (where applicable), packet tracing, and diagnostics.
Implement and troubleshoot TN3270 server configurations, including port management, SSL/TLS enablement, session pooling, and workstation/client interoperability.
Managed File Transfer & Secure Connectivity
Support Connect:Direct (NDM) : node configuration, Secure+ parameters, performance tuning, checkpoint/restart, and partner onboarding.
Configure and support FTP/FTPS/SFTP/SFTPS services on z/OS, including TLS/SSH ciphers, certificates/keys, SAF keyrings, user authentication, exits, and logging.
Own Policy Agent (PAGENT) configurations for IPSec and AT‑TLS policies; implement application‑aware TLS enablement and certificate rotation in partnership with Security.
Monitoring, Operations & Troubleshooting
Use NetView/SA to automate message handling, operator commands, resource start/stop, and recovery actions for network services.
Employ MainView or Omegamon to monitor availability, response times, and resource utilization; set thresholds/alerts and drive incident response.
Perform advanced diagnostics (packet trace, IPCS traces for TCP/IP, VTAM traces, console/SYSLOG review); lead root‑cause analysis and permanent corrective actions.
Governance, Change & Documentation
Create and maintain network runbooks , standards, and configuration baselines (TCPIP profiles, VTAM members, TN3270 parms, Policy Agent rules).
Prepare well‑formed change records with risk analysis, validation plans, and back‑out procedures; participate in CABs.
Collaborate with Security on vulnerability remediation , cipher/hardening changes, and compliance evidence.
Reliability, DR & Performance
Engineer high‑availability configurations (Sysplex Distributor, dynamic VIPA, redundancy/failover paths).
Participate in DR/Recovery tests ensuring communications stack, TN3270, and file transfer services are restored and validated.
Analyze performance data to reduce latency, eliminate bottlenecks, and improve throughput for application traffic and file transfers.
Who You Are
12+ years working with z/OS Communications Server (VTAM & TCP/IP) and TN3270 in enterprise environments.
Proven experience supporting Connect:Direct/NDM , FTP/FTPS , SFTP/SFTPS , and Policy Agent (AT‑TLS/IPSec) configurations end‑to‑end.
Hands‑on with NetView/SA for operational automation and with MainView or Omegamon for monitoring and diagnostics.
Strong troubleshooting skills: TCP/IP traces, VTAM traces, packet analysis, certificate/crypto issues, authentication/SAF integrations.
Proficiency with z/OS operations (JES2, SDSF, console, RACF integrations) and change governance in regulated environments.
Solid understanding of TLS/SSL, SSH, PKI, and SAF keyring management on z/OS.
Preferred / Nice to Have
Experience with Sysplex networking constructs (Sysplex Distributor, DVIPA), HiperSockets , EE , and VIPA policies .
Familiarity with automation scripting (REXX, NetView pipelines/command lists) for operational tasks.
Exposure to firewall/proxy integrations, DNS, SMTP on z/OS, and load balancing for TN3270 or IP workloads.
Performance tuning for Connect:Direct (session concurrency, buffer sizes, compression, Secure+ ciphers).
Core Competencies
Analytical problem‑solving under time pressure; strong triage and RCA discipline.
Clear written and verbal communication with Infra, App, Security, and Vendor teams.
Ownership, attention to detail, and documentation rigor.
Bias for automation, reliability, and security‑by‑design.
Success Measures (KPIs)
Availability & MTTR: Reduced incidents/outages; faster recovery through automation and clear runbooks.
Throughput & Latency: Improved performance for TN3270 sessions, application flows, and file transfers.
Change Quality: High change success rate; minimal emergency/back‑outs.
Security & Compliance: Timely cipher/hardening updates; clean audit results.
Operational Efficiency: Reduction in manual tasks via NetView/SA automation; proactive monitoring thresholds.
