Core Responsibilities

Primary Functions

Lead end-to-end upgrade projects for operating systems, middleware, databases, application stacks and firmware, including scoping, scheduling, rollback planning, execution, validation and post-upgrade support across dev, QA, staging and production environments.
Develop detailed upgrade plans and runbooks that include pre-upgrade checks, step-by-step procedures, validation checklists, performance benchmarks, rollback steps, and estimated downtime, ensuring plans are auditable and repeatable.
Design, build and maintain automation scripts, orchestration playbooks and CI/CD pipelines (Ansible, Terraform, Jenkins, GitLab CI, etc.) to standardize and accelerate upgrade operations while reducing manual error.
Coordinate cross-functional upgrade windows with product owners, QA, security, database administration and infrastructure teams to align on timing, cut-over procedures and business impact mitigation.
Execute complex in-place and rolling upgrades for clustered and distributed systems (Kubernetes clusters, VMs, bare-metal farms), ensuring consistency of configurations, stateful services and network dependencies.
Validate upgrade success using automated smoke tests, integration tests and system health checks; analyze telemetry and logs (Prometheus, ELK/EFK, CloudWatch) for regressions and performance deviations.
Implement and maintain version control, change tickets and approval workflows (JIRA, ServiceNow) for upgrades, including clear documentation of approvals, exceptions and remediation actions for audits.
Create and maintain rollback procedures that enable rapid, safe reversion to known-good states; conduct dry-run rollback tests and ensure backups/snapshots are available and tested.
Manage patch management and vulnerability remediation upgrades in coordination with security teams, prioritizing critical CVE patches and ensuring compliance with organizational security policies.
Lead upgrade validation efforts for database schema migrations, data integrity checks and compatibility testing, coordinating with DBAs to ensure ACID properties and minimal data disruption.
Troubleshoot and remediate upgrade failures and performance regressions in real-time, applying root cause analysis (RCA), hotfixes and mitigations while communicating status to stakeholders.
Evaluate and recommend tools, frameworks and best practices for upgrade orchestration, automation, monitoring and rollback to continuously improve upgrade velocity and reliability.
Create and maintain comprehensive documentation, runbooks, knowledge base articles and post-mortems for each upgrade project to enable operations handover and continual learning.
Conduct risk assessments and impact analyses for proposed upgrades, identifying single points of failure, backward compatibility issues and third-party dependency constraints.
Plan and execute blue-green and canary upgrade strategies for zero-downtime deployments when appropriate, instrumenting metrics and automation to detect and stop bad rollouts.
Coordinate hardware and firmware upgrades for network devices, storage controllers and servers, ensuring compatibility with current software stacks and minimizing service disruption.
Lead upgrade rehearsals and pre-cutover dry runs in test and staging environments to validate processes, timing and rollback steps before production execution.
Mentor and train operations, support and on-call teams on upgrade procedures, emergency rollback, and post-upgrade diagnostics to ensure 24/7 coverage and knowledge redundancy.
Ensure compliance with regulatory and internal change control processes; prepare upgrade change requests, risk matrices and communication plans for stakeholders and auditors.
Monitor and report upgrade KPIs: success rate, mean time to upgrade (MTTU), mean time to recover (MTTR), number of rollbacks, and post-upgrade incidents, driving continuous improvement initiatives.
Integrate upgrade workflows with configuration management and infrastructure-as-code repositories to maintain reproducible system state and simplify drift detection.
Work with product management to schedule version upgrades that align with release calendars, ensuring backward compatibility and migration paths for customers.
Partner with vendors and third parties for appliance upgrades, support escalations and firmware releases, ensuring vendor patches are applied and validated in enterprise environments.
Design and implement canary and feature-flag driven upgrade approaches to reduce blast radius and enable incremental rollouts with automated rollback triggers.

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.
Assist in capacity planning for upgrade windows and resource allocation across environments.
Provide on-call and post-upgrade incident response support as needed to restore degraded services.
