. About The Role

We are seeking an Infrastructure Support Engineer (L2) with a passion for cloud infrastructure and open‑source platforms to join our expanding System Engineering function. This role is pivotal in establishing our follow‑the‑sun operational model, providing critical coverage for live services during regional operational windows.

As an L2 Engineer, you will be the front‑line shield for our production environments. You will ensure platform stability, mitigate incidents, and collaborate with both incoming US Senior Engineers and our EMEA‑based strategic development teams. This position offers a distinct, accelerated progression plan designed to transition you into a Senior Systems Architect over time.

What You’ll Be Doing (Responsibilities)

• Live Service Operations: Monitor, triage, and resolve complex L2 incidents across our Unix/Linux and OpenStack cloud environments to safeguard customer SLAs.
• Platform Support: Provide hands‑on operational support and maintenance across compute, networking, and virtualization layers, specifically focusing on OpenStack Neutron (SDN) and OpenStack Ironic (bare‑metal provisioning).
• Follow‑the‑Sun Coverage: Operate effectively within a rotating shift framework to maintain seamless system reliability during non‑EMEA hours, paving the way for future APAC systems onboarding.
• Knowledge Management: Convert real‑time troubleshooting insights into structural capital by creating, refining, and updating standard operating procedures (SOPs) and technical runbooks.
• Cross‑Functional Collaboration: Partner with incoming US‑based Senior Engineers and handle structured escalations to EMEA core tooling developers when deep code mutations are required.

About You (Requirements)

• Linux/Unix Systems Administration: Proven commercial experience managing and troubleshooting Linux‑based infrastructure at scale.
• OpenStack Core Competency: Hands‑on experience working with or maintaining OpenStack ecosystems in production or large‑scale staging environments.
• Virtualisation Insights: Practical exposure to hypervisors and virtualization technologies (e.g., KVM, Proxmox).
• Analytical Triage Mindset: A methodical, right‑first‑time approach to incident investigation, performance bottlenecks, and root‑cause analysis.
• Communication & Documentation: Excellent English communication skills, with a proactive approach to technical writing and knowledge sharing.

Nice to Have

• Exposure to cloud‑native technologies and container orchestration (Kubernetes).
• Familiarity with infrastructure automation tooling (Ansible, Terraform, Python/Bash scripting).

What We Can Offer You

• Highly competitive package (base + equity) with reviews every 12 months.
• Human‑First Flexibility: We trust Nscalers to deliver, giving you the autonomy to shape your day around life's moments.
• A dynamic progression plan tailored specifically to your ambitions, with explicit mentorship towards Senior Engineering paths.
