Core Responsibilities

Primary Functions

  • Plan, schedule, and coordinate end-to-end upgrade activities (hardware, firmware, software, and network) across customer sites and data centers, ensuring minimal business disruption and adherence to maintenance windows.
  • Perform pre-upgrade site surveys and readiness checks (power, rack space, cabling, network configuration, software prerequisites) to confirm environment suitability and identify rollback points.
  • Build, validate, and execute detailed upgrade runbooks and checklists that include step‑by‑step procedures, version mappings, pre/post-validation tests, and rollback instructions.
  • Coordinate with stakeholders — engineering, operations, IT security, vendors, and customer points-of-contact — to obtain approvals, schedule windows, and communicate status updates before, during, and after upgrades.
  • Execute on-site and remote software and firmware upgrades for servers, switches, routers, storage arrays, controllers, and IoT/network devices while following strict change control and CAB (Change Advisory Board) requirements.
  • Perform configuration changes and migrations (e.g., OS patching, software version upgrades, configuration templates, VLAN and routing updates) and validate services post-deployment to ensure operational integrity.
  • Conduct functional and regressional validation tests including smoke tests, I/O verification, performance baselines, and application-level checks to confirm successful upgrades and detect regressions.
  • Troubleshoot and remediate upgrade failures, identify root causes, and implement corrective actions; escalate complex technical issues to engineering teams with comprehensive logs and diagnostics.
  • Maintain full version control of device firmware/software images, configuration backups, and asset inventories; perform secure backups prior to any upgrade activity to enable rapid rollback if needed.
  • Manage ticket lifecycle in ITSM systems (e.g., ServiceNow, JIRA) including creating RFCs, updating work notes, logging incidents arising from upgrades, and closing tickets with detailed post-upgrade documentation.
  • Execute rollback plans when an upgrade negatively impacts services and coordinate communication with customers and stakeholders until restoration is complete.
  • Implement and verify security hardening changes as part of upgrade activities, including patching vulnerabilities, updating certificates, and validating access control changes in accordance with security policies.
  • Run scripted and manual automation tasks to streamline repetitive upgrade steps (scripting in Bash, PowerShell, Python or automation tools) and collaborate with DevOps teams to integrate upgrades into CI/CD pipelines where applicable.
  • Validate interoperability and compatibility between firmware/software versions and dependent systems (applications, middleware, databases) to avoid cascading failures.
  • Ensure compliance with health, safety, and on-site access policies during field visits; follow PPE, ESD, and lockout-tagout procedures when handling equipment.
  • Document all changes comprehensively for audits: pre-upgrade risk assessment, CAB approvals, test results, configuration diffs, and post-deployment verification reports.
  • Track metrics and KPIs for upgrades (success rate, mean time to upgrade, rollback frequency, downtime, customer impact) and provide regular reports to management to drive continuous improvement.
  • Provide on-call support for escalations related to upgrade-induced outages and participate in post-incident reviews to identify lessons learned and prevent recurrence.
  • Conduct customer and internal knowledge transfer sessions, training materials, and hand-offs after major upgrade projects to enable support teams to manage the upgraded environment.
  • Coordinate spare parts, tools, and logistics for field upgrades including staging of pre-configured devices, parts replacement, and return merchandise authorization (RMA) handling.
  • Test and validate vendor-supplied patches and hotfixes in lab environments before production rollout, including interoperability and regression testing across typical customer scenarios.
  • Enforce change freeze and blackout windows per client policies and regulatory requirements and plan around business-critical events to minimize risk.
  • Support pilot upgrade programs, phased rollouts, and canary deployments to gather early feedback and reduce risk for large-scale upgrades.
  • Contribute to continuous improvement by documenting lessons learned, optimizing runbooks, and recommending automation or process changes to reduce upgrade time and error rates.

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.

Required Skills & Competencies

Hard Skills (Technical)

  • System upgrades and patch management for servers, network devices, storage, and embedded systems (experience with both on-site and remote deployments).
  • Hands-on experience with network technologies: TCP/IP, VLANs, routing (OSPF/BGP basics), switch configuration, and common network troubleshooting tools (ping, traceroute, tcpdump).
  • Firmware and software lifecycle management: image staging, firmware flashing, rollback procedures, and version control.
  • Familiarity with change management and ITSM platforms such as ServiceNow, JIRA, or BMC Remedy for RFC and ticket management.
  • Scripting and automation: proficiency in Bash, PowerShell, or Python for automation of upgrade steps and validation tasks.
  • Basic Linux and Windows system administration skills (patching, service management, log analysis).
  • Experience with configuration management and orchestration tools (Ansible, Puppet, Chef) or CI/CD pipelines for automated deployments.
  • Diagnostic and logging tools: ability to collect and interpret system logs, SNMP traps, syslog, and vendor diagnostic outputs.
  • Backup and restore procedures for configurations and system images; familiarity with snapshotting and data protection practices.
  • Knowledge of security practices related to upgrades: certificate management, vulnerability remediation, and compliance documentation.
  • Experience with lab validation environments and test plans for pre-production verification.
  • Use of monitoring and observability tools (Nagios, Zabbix, Prometheus, Datadog) to validate post-upgrade health.
