Qualifications

• Significant hands-on experience operating and troubleshooting Linux-based infrastructure at scale.
• Practical experience with bare-metal servers, GPUs, and the surrounding hardware and kernel stack.

Job description

Role overview

Join a small operations team as a senior infrastructure engineer responsible for keeping a large-scale GPU and bare-metal compute fleet healthy. The work spans the full infrastructure stack - Linux hosts, compute, networking, storage, provisioning, and cluster orchestration and centers on being the technical escalation point when complex issues arise. It is a hands-on, generalist role with a strong automation mindset rather than a traditional ticket-driven administration position.

Responsibilities

• Operate and troubleshoot production infrastructure across Linux servers, GPUs, networking, storage, and orchestration systems.
• Serve as the escalation point for hard problems, driving incidents from initial investigation through root-cause analysis and resolution.
• Own end-to-end operational workflows including provisioning, configuration, validation, maintenance, remediation, and decommissioning.
• Build automation and internal tooling that removes repetitive work and lets the fleet scale without linear headcount growth.
• Identify recurring failure modes and partner with infrastructure engineering teams to make systems more reliable and repeatable.
• Participate in a primary/secondary on-call rotation supporting production infrastructure.

Requirements

• Significant hands-on experience operating and troubleshooting Linux-based infrastructure at scale.
• Practical experience with bare-metal servers, GPUs, and the surrounding hardware and kernel stack.
• Familiarity with hardware management and provisioning interfaces such as PXE, BMC, IPMI, Redfish, or iDRAC.
• Experience with distributed or high-performance storage systems (e.g., VAST, Ceph, GPFS, or WEKA).
• Experience with infrastructure-as-code, configuration management, or GitOps workflows.
• Residing in Singapore and able to work Monday-Friday, 8:00 AM-5:00 PM local time (UTC+8) with periodic on-call.

Nice to have

• Background operating or troubleshooting high-speed data center networking.
• Comfort switching between deep debugging of a single failure and stepping back to design systemic improvements.

Benefits and work setup

• Remote role based in Singapore with a Monday-Friday daytime window plus after-hours on-call participation.
• Anticipated annual base salary range of SGD 165,000-220,000, plus discretionary bonus and meaningful equity.
• Comprehensive medical, dental, and vision coverage for employees and eligible dependents.
• Retirement savings support (401(k) matching or pension contributions depending on location).
• Unlimited paid time off, company holidays, floating holidays, and a two-week company-wide winter break.
• Paid parental and family leave, annual learning and research budget, and wellness plus work-from-home stipends.
• Four-week paid sabbatical after four years of service, flexible scheduling, and in-office meals at company hubs.
