The ideal candidate will have strong technical expertise, a disciplined approach to system reliability and security, and the ability to collaborate effectively across technical teams.
Key Responsibilities
- Linux engineering: Design, harden, and maintain RHEL/Ubuntu systems; implement HA/DR strategies and patching standards.
- Networking troubleshooting: Diagnose issues across OSI/TCP/IP layers (DNS/DHCP, routing, VLANs, firewalls, SSL/TLS/certs).
- Load balancing & traffic management: Deploy, configure, and tune F5 BIG‑IP (LTM/GTM, iRules) and HAProxy for L4–L7 services.
- Azure infrastructure: Build and secure IaaS/PaaS (VMs, VNets, NSGs, UDRs, Azure Load Balancer, Azure Firewall, Storage).
- Tooling & automation: Develop utilities/services in C* and Python*; integrate with CI; create health checks and runbooks.
- Observability & performance: Implement metrics/logging; profile and tune kernel/app performance; root‑cause analysis for incidents.
- Security & compliance: System hardening (SELinux, auditd), secrets management, least‑privilege/IAM alignment, vulnerability remediation.
- Collaboration: Partner with App/Network/SecOps teams; document architectures/runbooks; contribute to post‑mortems and RCA.
Core Competencies:
- Expertise in designing, hardening, and maintaining Linux systems (RHEL/Ubuntu) in production environments, with a focus on system security, performance optimization, and high availability
- Strong hands-on experience in building, securing, and supporting cloud infrastructures across IaaS and PaaS environments, particularly within Microsoft Azure, including virtual machines, networking, storage, and security
- In-depth understanding of networking protocols and troubleshooting at all OSI/TCP/IP layers. Expertise in diagnosing and resolving issues related to DNS/DHCP, routing, VLANs, firewalls, and SSL/TLS
- Ability to work effectively in a cross-functional team environment (with App/Network/SecOps teams) to document architectures, create runbooks, and contribute to post-mortems and root cause analysis for incidents
Education and Experience:
- 10+ years in Linux systems engineering/administration in production environments
- Experience designing, building, and supporting mission‑critical infrastructure across Azure and on‑prem environments
- Experience writing C and Python for systems tooling, performance, or networking use cases
- Hands‑on experience designing, deploying, and tuning F5 BIG‑IP and HAProxy
- Strong networking fundamentals and troubleshooting (TCP/IP, routing, DNS, SSL/TLS)
- Practical experience building and supporting Azure infrastructure (compute, networking, storage)
- Bachelor’s Degree in Computer Science, Information Technology, Engineering, or a related field
- Equivalent experience in Linux systems engineering, cloud infrastructure, and networking may be considered in place of formal education
