Our technology and innovation, partnerships and networks combine to deliver a unique set of products and services that help people, businesses and governments realize their greatest potential.

Title and Summary

Site Reliability Engineer I

Overview

The Service Operations Technology (SOT) BizOps team is seeking a Site Reliability Engineer I to support and continuously improve enterprise infrastructure, configuration management, discovery, asset and inventory, automation, and operational technology platforms. This role provides an opportunity to develop expertise at the intersection of software engineering and production operations, with exposure to reliability, observability, automation, operational readiness, incident management, and continuous improvement. The successful candidate will support production services while developing engineering skills that help reduce operational toil, improve service visibility, automate repetitive activities, and improve platform reliability. Working with software engineering, infrastructure, product, cybersecurity, and operations teams, this position provides broad exposure to the technologies and engineering practices used to operate business-critical enterprise services.

Role Business Operations supports operational excellence and production readiness for the platforms we support. The team partners with software engineering and technology teams throughout the service lifecycle to help maintain reliable, observable, secure, scalable, and operationally supportable services. As a Site Reliability Engineer I, you will develop practical experience operating enterprise technology platforms while applying SRE and DevOps principles to production support. You will perform platform maintenance, monitoring, troubleshooting, deployment support, and operational validation while contributing to automation and engineering improvements. As your technical knowledge develops, you will have opportunities to contribute to increasingly complex automation, observability, reliability, and platform-engineering activities with guidance from experienced engineers. The SRE framework identifies observability, programming and scripting, systems and network administration, cloud computing, reliability and scalability, DevOps practices, troubleshooting, capacity/performance, IT Service Management, and proactive monitoring as core skills within the discipline. At SP9, the framework classifies these skills at the Foundational level.

Responsibilities

Support the day-to-day operation and maintenance of enterprise technology platforms and supporting infrastructure.
Perform routine system and application maintenance using established procedures and engineering standards.
Support monitoring of service health, availability, performance, capacity, and operational events.
Troubleshoot and resolve basic-to-moderate issues across application, infrastructure, network, operating-system, and integration layers.
Escalate complex technical issues while assisting experienced engineers with investigation and resolution.
Support production incidents and participate in root cause analysis and corrective-action activities.
Perform routine Linux/Unix system administration and support related enterprise infrastructure.
Participate in operating system and application upgrades, patching, vulnerability remediation, releases, deployments, and production changes.
Support production-readiness reviews and operational-validation activities for new or changed services.
Identify opportunities for automation and contribute to scripts and tools that reduce repetitive operational activities and toil, with guidance from experienced engineers.
Contribute to monitoring, alerting, health-check automation, dashboards, and observability improvements using enterprise technologies such as Splunk and Dynatrace. SOT activities document both technologies in operational monitoring work.
Work with REST APIs and system integrations in support of automated operational workflows.
Develop practical experience with source control, CI/CD, release pipelines, deployment automation, and configuration-management technologies.
Assist with capacity, performance, reliability, and system-health analysis.
Follow incident, problem, change, configuration-management, security, and operational risk-management practices.
Maintain technical documentation, operating procedures, troubleshooting guides, and knowledge articles.
Participate in technical reviews and quality checks that support service stability and operational readiness.
Collaborate with product, software engineering, infrastructure, cybersecurity, and operations teams.
Participate in knowledge-sharing activities and continuously develop technical expertise in SRE, automation, observability, cloud, and platform engineering.

Position Qualifications Required Qualifications

Bachelor's degree in Computer Science, Engineering, Mathematics, Information Technology, or a related discipline, or equivalent practical experience.
Foundational knowledge of Linux/Unix systems and system-administration concepts.
Foundational programming or scripting experience using Python, PowerShell, Bash, Java, Go, or similar technologies.
Understanding of networking fundamentals including TCP/IP, DNS, HTTP/HTTPS, SSH, and basic network troubleshooting.
Understanding of software engineering and automation concepts.
Familiarity with monitoring, logging, alerting, and observability concepts.
Systematic problem-solving and troubleshooting abilities.
Understanding of production support, incident response, and change-management practices.
Ability to document technical procedures, issues, and resolutions effectively.
Strong written and verbal communication skills.
Ability to collaborate effectively across technical and business teams.
Strong sense of ownership, curiosity, and interest in automation and continuous learning.

Preferred Qualifications

Experience supporting enterprise applications or infrastructure in production environments.
Experience with Python, PowerShell, Bash, or similar programming, scripting, and automation technologies.
Experience developing or supporting REST APIs, system integrations, and automated operational workflows.
Experience with Splunk, Dynatrace, or comparable enterprise monitoring and observability technologies.
Familiarity with source-control and repository technologies such as Bitbucket and Git, including branch and pull-request workflows.
Familiarity with CI/CD, release, and deployment technologies such as Jenkins and XLR.
Familiarity with configuration management and infrastructure automation technologies such as Chef and Ansible.
Exposure to workflow or orchestration technologies such as Apache NiFi or comparable platforms. NiFi has been discussed within SOT in connection with orchestrating URL/API monitoring and sending resulting logs to Splunk.
Familiarity with AWS, Azure, or enterprise cloud environments.
Experience with CMDB, discovery, asset management, inventory management, or configuration-management technologies.
Familiarity with BMC Discovery or comparable infrastructure-discovery technologies.
Experience with Remedy or comparable ITSM technologies.
Understanding of SSL/TLS and certificate management.
Familiarity with Agile, DevOps, SRE, and modern software-delivery practices.
Relevant Linux, cloud, security, automation, DevOps, or SRE certifications.
