Senior Jenkins Administator

Company:

Qualcomm Intl Inc., Mexico Branch Office

Job Area:

Information Technology Group, Information Technology Group > IT Engineering

General Summary:

We are looking for a Senior Jenkins Administrator to own and evolve our enterprise Jenkins platform used by multiple engineering teams. In this role, you will manage Jenkins as a highly available, secure, scalable CI/CD service, deployed across Linux virtual machines, Kubernetes clusters, and cloud infrastructure. You will lead platform operations, reliability engineering, security hardening, and automation—ensuring Jenkins remains a dependable backbone for build, test, and deployment workflows. 

You will partner closely with application teams, SRE/Platform Engineering, Security, and Infrastructure to deliver a robust Jenkins service with clear operational standards, observability, and governance. 

Responsibilities

Jenkins Platform Operations & Administration 

• Own day‑to‑day administration of Jenkins controllers (shared and/or dedicated), including configuration, upgrades, plugin lifecycle management, and scaling. 

• Manage Jenkins at an infrastructure/platform level: controller sizing, agent strategy, capacity planning, and overall platform reliability. 

• Standardize Jenkins configurations using “configuration as code” practices (e.g., controller configuration management, repeatable provisioning). 

• Implement operational runbooks, on‑call readiness, incident response procedures, and root cause analysis for Jenkins platform issues. 

Reliability, Availability & Performance Engineering 

• Ensure high availability, resilience, and performance of Jenkins infrastructure across VMs and Kubernetes. 

• Design and implement backup/restore strategies (controller configuration, job metadata where applicable, secrets references, and artifacts integration points). 

• Define and track SLOs/SLAs, platform health KPIs, and continuous improvements to reduce MTTR and operational toil. 

• Troubleshoot complex issues spanning Jenkins, agents, networking, storage, DNS, certificates, identity, and underlying OS/K8s layers. 

Kubernetes, Containers & Build Agents 

• Operate Jenkins on Kubernetes (where applicable), including controller deployments, ingress, persistent storage, and network policies. 

• Build and maintain enterprise-grade agent container images (toolchains, security baselines, patching, provenance). 
• Optimize agent provisioning strategy (static vs. dynamic agents), resource quotas/limits, node/pod scheduling, and isolation for multi‑tenant environments.

• Establish governance around agent images, tool versions, and dependency management to ensure consistency and reproducibility.

Security, Compliance & Governance

• Implement secure Jenkins patterns: RBAC/authorization, least privilege, credential governance, secrets management integrations, and auditability.

• Drive platform hardening: secure plugin usage, controller/agent isolation, network restrictions, and secure defaults.

• Partner with Security teams to remediate vulnerabilities and ensure compliance with enterprise policies (e.g., access reviews, logging, change control).

Cloud & Infrastructure Integration

• Support Jenkins deployments and integrations across cloud environments (AWS/Azure/GCP or internal cloud), including IAM concepts and connectivity patterns.

• Integrate Jenkins with enterprise services such as artifact repositories, container registries, SCM systems, secret stores, and observability stacks.

• Automate provisioning and changes using Infrastructure as Code (IaC) and CI/CD for platform components.

Stakeholder Enablement & Support

• Provide best practices, consultation, and platform support for application teams consuming Jenkins (tenants).

• Create clear documentation, onboarding guides, and self-service patterns to improve developer experience while maintaining governance.

• Participate in change management, release planning, and communications for platform maintenance windows and upgrades.

Minimum Qualifications

• 3 years’ experience with a bachelor’s degree, 5 years without of the following: CI/CD, DevOps, SRE, or Platform Engineering with 3+ years hands-on Jenkins administration in enterprise environments. 

• Strong experience managing Jenkins controllers and plugins, including upgrades, compatibility management, and operational troubleshooting. 

• Solid Linux systems administration skills (processes, systemd, networking, storage, performance, troubleshooting). 

• Working experience with Kubernetes concepts (deployments, services/ingress, PV/PVC, RBAC, namespaces, resource management, troubleshooting). 

• Strong understanding of Docker/containers (image creation, registries, runtime basics, security scanning fundamentals). 

• Experience with scripting and automation (e.g., Bash, Python, Groovy, or similar) for operational tasks and repeatability. 
• Knowledge of authentication/authorization integrations (SSO/OIDC/SAML/LDAP as applicable) and credential management practices. 

• Familiarity with monitoring/logging/observability tools (e.g., Prometheus/Grafana, ELK, Splunk, Cloud logging) and incident management. 

• Comfortable working in a multi-tenant environment with governance, security controls, and reliability expectations.

Desired Qualifications

• Experience running Jenkins in Kubernetes at scale, including controller resiliency patterns and dynamic agent provisioning. 

• Hands-on with Jenkins “as code” approaches (e.g., controller configuration automation, Job DSL concepts, pipeline governance at platform level). 

• Experience with Infrastructure as Code tools (Terraform, Ansible, Helm, Argo CD, etc.) to standardize Jenkins deployments and changes. 

• Knowledge of network/security controls relevant to CI/CD platforms (TLS/cert lifecycle, proxies, firewall policies, service mesh, mTLS concepts). 

• Experience integrating with enterprise tooling: 

• SCM (GitHub/GitLab/Bitbucket), Artifact repos (JFrog/Nexus), container registries, secret managers (Vault), ticketing/ITSM.

• Exposure to cloud security/IAM patterns and building secure pipelines for regulated environments. 

• Experience with scaling frameworks and autoscaling patterns for build agents (e.g., K8s autoscaling, queue-based scaling strategies). 

• Strong documentation skills and ability to build self-service enablement for development teams.

Additional Notes

• This role is focused on Jenkins platform administration and infrastructure, not on writing application pipelines. 

• The role requires participation in an on‑call rotation to ensure timely support during off‑hours.

Minimum Qualifications:

• 3+ years of IT-related work experience with a Bachelor's degree.
OR
5+ years of IT-related work experience without a Bachelor’s degree.
