The Role
Key Responsibilities
Communications Server (VTAM & TCP/IP)
- Configure, maintain, and optimize VTAM definitions (APPL, LUs, logmodes, major/minor nodes), EE/Highspeed 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 ATTLS policies implement applicationaware 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 rootcause 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 wellformed change records with risk analysis, validation plans, and backout procedures participate in CABs.
- Collaborate with Security on vulnerability remediation, cipher/hardening changes, and compliance evidence.
Reliability, DR & Performance
- Engineer highavailability 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 (ATTLS/IPSec) configurations endtoend.
- Handson 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 problemsolving 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 securitybydesign.
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/backouts.
- Security & Compliance: Timely cipher/hardening updates clean audit results.
- Operational Efficiency: Reduction in manual tasks via NetView/SA automation proactive monitoring thresholds.
