Ability to effectively manage and resolve high-severity production incidents.

Responsibilities

Support the full service lifecycle from design and implementation through deployment, operation, and optimization.
Serve as an operational owner for critical enterprise platforms, ensuring reliability, availability, performance, and scalability.

Monitor, maintain, and troubleshoot services in production environments.
Lead incident response, root cause analysis, and implementation of long-term corrective actions.
Drive automation initiatives that reduce operational toil and improve platform stability.
Support releases and deployments while ensuring production readiness and operational excellence.
Perform operating system maintenance, patching, vulnerability remediation, and lifecycle management.
Analyze operational data and ITSM activities to identify resiliency improvements and operational risks.

Platform Engineering & Automation

Engineers supporting platform engineering and automation may also:

Design and maintain deployment automation and infrastructure management solutions.
Support CI/CD pipelines and modern DevOps practices.
Develop tools, integrations, and automation that improve reliability, efficiency, and scalability.
Enhance platform visibility, operational effectiveness, and customer experience.
Evaluate emerging technologies and identify modernization opportunities.
Partner with engineering teams to improve deployment reliability and reduce operational risk.

Additional Qualifications

Experience with software engineering principles, automation, scripting, pipeline management, and system design.
Strong sense of ownership, urgency, and systematic problem-solving.
Experience debugging, optimizing, and automating complex technical environments.
Ability to manage competing priorities and work effectively with multiple stakeholders.
