In short

Qualcomm is seeking a Senior Jenkins Administrator to manage and enhance their enterprise Jenkins platform. This role involves ensuring high availability, security, and scalability across Linux, Kubernetes, and cloud environments, focusing on platform operations, reliability, and automation.

Responsibilities

Administer Jenkins controllers, including configuration, upgrades, plugin management, and scaling.
Manage Jenkins infrastructure at a platform level, including controller sizing, agent strategy, capacity planning, and reliability.
Standardize Jenkins configurations using "configuration as code" practices.
Implement operational runbooks, on-call readiness, incident response, and root cause analysis for Jenkins issues.
Ensure high availability, resilience, and performance of Jenkins infrastructure on VMs and Kubernetes.
Design and implement backup/restore strategies for Jenkins configurations and metadata.
Define and track SLOs/SLAs, platform health KPIs, and continuous improvements.
Troubleshoot complex issues across Jenkins, agents, networking, storage, and underlying OS/K8s layers.
Operate Jenkins on Kubernetes, including controller deployments, ingress, storage, and network policies.
Build and maintain enterprise-grade agent container images with security baselines and patching.
Optimize agent provisioning strategy, resource quotas, scheduling, and isolation.
Establish governance for agent images, tool versions, and dependency management.
Implement secure Jenkins patterns like RBAC, least privilege, credential governance, and secrets management.
Drive platform hardening through secure plugin usage, isolation, and secure defaults.
Partner with Security teams to remediate vulnerabilities and ensure compliance.
Support Jenkins deployments and integrations across cloud environments (AWS/Azure/GCP).
Integrate Jenkins with enterprise services like artifact repositories, container registries, SCM, secret stores, and observability stacks.
Automate provisioning and changes using Infrastructure as Code (IaC) and CI/CD.
Provide best practices, consultation, and platform support for application teams.
Create documentation, onboarding guides, and self-service patterns.
Participate in change management, release planning, and communications for platform maintenance.

Requirements

3 years’ experience with a bachelor’s degree, 5 years without of 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.
Ability to participate in an on-call rotation.

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.
