About The Position

The Senior Supplier Quality Engineer, Optics, ASIC, and Network Fabric owns supplier quality for networking silicon and interconnect hardware used in IREN’s AI data centers. This includes optical transceivers, AOC and DAC cables, fiber cabling, switch and NIC ASICs, and top-of-rack (TOR), leaf, and spine fabric switches. This senior individual-contributor role qualifies suppliers, establishes quality standards for mass-production deployment, and serves as the senior escalation point for supplier-related optics, ASIC, and fabric failures. It partners with Engineering, Technical Sourcing, Supply Chain Operations, Data Center Operations, and suppliers to meet cost, quality, and reliability targets at scale. IREN is an AI Cloud Service Provider delivering large-scale GPU clusters for AI training and inference. It owns and operates data centers powered by renewable energy and emphasizes responsible, sustainable operations. This role is hybrid in the San Francisco area; until IREN’s planned Santa Clara office opens, the position will work remotely and then transition to hybrid on-site work. The employee must reliably commute to the assigned office on scheduled in-office days and be willing to travel domestically and internationally to supplier, manufacturing partner, integration, and data center sites. Pre-employment screening, including a background check and substance testing, may be required under company policies. The expected base salary is USD $240,000–$300,000 per year. Total compensation may include an annual incentive bonus and long-term incentive equity. Relocation or a living-out allowance/per diem may be available depending on the successful candidate’s circumstances. The package also includes company-paid health coverage, disability insurance, a 401(k) with company match, PTO and paid holidays, professional development, and other health, financial, and wellness resources.
