As a Senior Platform Engineer on the Global CI/CD Platform team, you will design, build, and maintain the organization's software delivery platforms — including GitHub, Harness, SonarQube, Snyk, and Nexus Repository — leveraging AWS, Terraform, Docker, and Kubernetes to support the platform infrastructure. You will be responsible for the configuration, customization, and operational health of these platforms to meet the needs of engineering teams across the organization.

This role requires close collaboration with stakeholders across business units to gather requirements, design scalable solutions, and deliver reliable, secure CI/CD capabilities. The emphasis is on automation, developer experience, and platform reliability — enabling teams to ship software faster, safer, and more consistently. Your work will directly impact how the organization builds, tests, secures, and delivers software at scale.

What You Will Do:

• Administer, configure, and scale the organization's CI/CD platform toolchain — GitHub (Enterprise Cloud/Server), Harness, SonarQube, Snyk, and Nexus Repository — including platform upgrades, integrations, and day-to-day operational health.
• Design, implement, and optimize CI/CD pipelines, templates, and deployment strategies across multiple environments and business units.
• Manage GitHub Enterprise administration including org policies, repository governance, SSO/SAML configuration, and audit logging.
• Configure and maintain Harness CI/CD pipelines, connectors, delegates, and deployment strategies to support delivery teams across the organization.
• Develop and implement platform strategies to improve efficiency through automation and enhance the developer experience.
• Enable development teams to self-service CI/CD capabilities through documentation, reusable pipeline templates, and standardized components.
• Implement and enforce platform security controls including access management, secrets handling, and compliance with organizational security policies.
• Monitor platform performance and health, troubleshoot technical issues, provide technical support for CI/CD services, and enable systems with automated monitoring and alerting.
• Collaborate with stakeholders to gather requirements, build solution designs, and ensure scalability, resiliency, and efficiency of platform architectures — including responding to emerging requirements and ambiguous technology decisions.
• Create system guidelines, process documentation, runbooks, and training materials for the organization.
• Support tool consolidation efforts by migrating CI/CD pipelines, repositories, and artifact stores from disparate systems to the organization's centralized platform.
• Manage vendor relationships, licensing, support escalations, and upgrade planning for platform tooling.
