Must have
Teradata platform expertise
• Deep knowledge of Teradata architecture: parsing, BYNET, AMP, vproc, fallback, hashing, PDCR, fallback, and spool management.
• Data distribution and primary index design; collecting statistics and understanding optimizer behavior.
• Experience with recent Teradata versions and releases migration/upgrade planning: TD 16.XX, TD 17.XX and preferably TD 20.XX.
System administration
• Provisioning and managing Teradata nodes and clusters (physical and virtual).
• OS-level skills: Linux administration (SLES/RHEL/CentOS/Oracle Linux) for Teradata on Linux, including kernel tuning, package management, user and permissions management.
• Storage subsystem knowledge: SAN, NAS, Fibre Channel, LUNs, RAID, and how storage impacts Teradata I/O and spool.
Performance tuning and troubleshooting
• SQL query and plan analysis; collecting and interpreting Explain plans.
• Workload management (WLM) and resource allocation: query prioritization, throttling, and KRI/SLAs.
• Monitoring and diagnostics: using Teradata tools and logs to analyze spool, CPU, memory, disk I/O, network, BYNET contention.
Backup, recovery & high availability
• Best practices for backups restore procedures, and disaster recovery (DR) planning and testing.
• Knowledge of fallback, AMP resilience, replication methods and physical vs logical protection.
Security & compliance
• DB and platform-level security: roles, privileges, LDAP/Kerberos integration, encryption (at rest/in transit), auditing and compliance (SOx and Others as applicable).
• Secure configuration and hardening practices.
Networking & infrastructure
• Network architecture for Teradata clusters, VLANs, link aggregation, low-latency requirements, and BYNET tuning.
• Integration with enterprise infrastructure: DNS, NTP, monitoring stacks, and identity providers.
Automation, scripting & tools
• Scripting languages: Bash, Python, Perl for automation, maintenance, and custom monitoring. – one of them
• Configuration management and automation tools: Ansible, Terraform, Chef, or Puppet (as used in the enterprise). – one of them
• Familiarity with Teradata utilities and tools: BTEQ, FastLoad, MultiLoad, TPT (Teradata Parallel Transporter), DBSControl, Viewpoint, Teradata Studio/SQL Assistant. – one of them
Observability & tooling
• Use of monitoring/alerting tools (Viewpoint, Prometheus, Grafana, Splunk, Nagios, etc.) and designing dashboards and alerts. One of them, View point is mandatory
• Capacity planning, trending, and forecasting for CPU, disk, spool, and concurrency.
Soft skills & organizational capabilities
• Incident management and on-call experience
• Leading postmortems, RCA (root-cause analysis), implementing corrective actions.
• Communication and stakeholder management: vendors, management and applications
• Translate technical impacts to business stakeholders; coordinate with DBAs, developers, network/storage teams, and vendors.
