全职 Senior Linux Engineer 工作, 薪水, LPS 公司招聘中 - Ricebowl

Role Summary:

We're looking for a Senior Linux Engineer to own the design, performance, and reliability of our Linux server estate. You'll be the go-to expert for Linux systems architecture, automation, and troubleshooting, spanning on-premises and cloud-hosted infrastructure (AWS and Azure).

What You'll Do:

• Own the architecture, build, and ongoing administration of Linux servers (RHEL/CentOS, Ubuntu, Debian, AWS Linux or similar) across the environment.
• Perform deep-level troubleshooting across kernel, filesystem, storage, memory, and networking layers.
• Harden systems against security vulnerabilities: patch management, CIS benchmarking, access controls, and audit logging.
• Support and extend infrastructure into AWS and Azure where workloads run in the cloud — provisioning compute/storage, managing IAM, and integrating cloud-hosted Linux systems into existing monitoring and automation.
• Lead capacity planning, performance tuning, and disaster recovery/backup strategy for Linux-based systems.
• Participate in on-call rotation, drive incident response, and lead root-cause analysis and postmortems.
• Document system architecture, runbooks, and standard operating procedures.
• Mentor junior and mid-level engineers on Linux administration best practices and troubleshooting methodology.
• Partner with security, networking, and application teams to ensure systems meet compliance and reliability requirements.

What We're Looking For:

• 5-7 years of experience in Linux systems administration/engineering, ideally across large-scale, production environments.
• Deep expertise in Linux internals: process management, filesystems, networking (TCP/IP, routing, firewalls), storage, and performance tuning.
• Strong scripting/automation skills (Bash required; Python or similar strongly preferred)..
• Working knowledge of virtualization (VMware, KVM, or similar) and containerization (Docker; Kubernetes a plus).
• Practical experience running Linux workloads on AWS and/or Azure — provisioning, IAM, networking, and cost-aware operations.
• Strong understanding of security hardening practices and compliance requirements (CIS benchmarks, patch management, audit logging).
• Excellent troubleshooting skills and the ability to stay methodical under pressure during production incidents.
• Strong communication skills and the ability to document and explain technical work clearly.

Certifications (Preferred):

• Red Hat Certified Engineer (RHCE) or Red Hat Certified System Administrator (RHCSA).
• LFCS/LFCE (Linux Foundation Certified Sysadmin/Engineer) a plus.
• AWS Certified SysOps Administrator or Solutions Architect - Associate (nice to have).
• Microsoft Certified: Azure Administrator Associate (nice to have).
