Core Responsibilities

Primary Functions

Maintain and administer Linux and Windows servers, including installation, configuration, user management, patching, and performance tuning to ensure secure and stable production and non-production environments.
Monitor system health and availability through enterprise monitoring tools (e.g., Nagios, Prometheus, Datadog, Zabbix), respond to alerts, and execute escalation procedures to minimize downtime and meet SLAs.
Troubleshoot infrastructure incidents end-to-end, perform root cause analysis, and implement corrective actions, documenting findings and lessons learned for future prevention.
Deploy and manage virtualized infrastructure using VMware, Hyper-V, or equivalent platforms, including provisioning VMs, managing templates, snapshots, and resource allocations.
Support cloud infrastructure operations on AWS or Azure: provisioning instances, managing IAM, optimizing costs, and following cloud security best practices under guidance from senior engineers.
Implement and maintain backup and disaster recovery solutions (e.g., Veeam, NetBackup), perform periodic restores to validate backup integrity, and update recovery runbooks.
Automate repetitive operational tasks using scripting languages and automation tools (e.g., Bash, PowerShell, Python, Ansible) to reduce manual effort and increase deployment reliability.
Participate in patch management lifecycle: test patches in staging, schedule rollouts, monitor post-patch stability, and maintain patching documentation and compliance records.
Manage Active Directory, DNS, DHCP, group policies and account lifecycle operations including onboarding/offboarding and privilege management in coordination with security teams.
Collaborate with network teams to troubleshoot and tune TCP/IP, routing, switching, firewall rules, load balancers, and VPN connectivity impacting application availability.
Install, configure, and support containerized workloads and orchestration basics (Docker, Kubernetes) as part of transitioning applications to modern deployment models.
Support CI/CD pipelines and deployment automation by integrating infrastructure changes into version-controlled repositories and automation tools (e.g., Jenkins, GitLab CI/CD).
Maintain infrastructure-as-code templates (CloudFormation, Terraform) under guidance; perform validations, run plan/apply in non-production environments, and assist in safe rollouts.
Enforce security controls and compliance requirements by applying hardening standards, coordinating vulnerability remediation, and assisting with audits and security scans.
Maintain system inventory, asset lifecycle records, and configuration documentation to support change management and reduce mean time to repair (MTTR).
Perform capacity planning and trend analysis by collecting system metrics, forecasting resource needs, and escalating recommendations for scaling or optimization.
Provide second-line support for escalated tickets from helpdesk or operations, diagnose issues, and collaborate with application owners to achieve fast resolution.
Participate in on-call rotations for incident response, maintain accurate incident logs, and contribute to post-incident reviews with actionable remediation plans.
Assist in the rollout of new infrastructure projects, including test plans, deployment steps, rollback procedures, and creating runbooks for operational teams.
Maintain monitoring dashboards and alert thresholds to align with business objectives and reduce false positives while ensuring timely detection of real issues.
Apply change control procedures for infrastructure changes, prepare change requests, communicate planned outages to stakeholders, and follow rollback and remediation processes.
Support database and middleware administrators with platform-level tasks such as OS tuning, backups, and resource allocation to ensure application performance.
Continuously learn and adopt new tools, best practices, and technologies to improve operational efficiency and keep the infrastructure up-to-date with industry standards.
Document operational processes, configuration baselines, runbooks, and standard operating procedures (SOPs) to enable knowledge transfer and repeatability across the team.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis.
Contribute to the organization's data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.
