About Celestial AI

As Generative AI continues to advance, the performance drivers for data center infrastructure are shifting from systems-on-chip (SOCs) to systems of chips. In the era of Accelerated Computing, data center bottlenecks are no longer limited to compute performance, but rather the system’s interconnect bandwidth, memory bandwidth, and memory capacity. Celestial AI’s Photonic Fabric™ is the next-generation interconnect technology that delivers a tenfold increase in performance and energy efficiency compared to competing solutions.

The Photonic Fabric™ is available to our customers in multiple technology offerings, including optical interface chiplets, optical interposers, and Optical Multi-chip Interconnect Bridges (OMIB). This allows customers to easily incorporate high bandwidth, low power, and low latency optical interfaces into their AI accelerators and GPUs. The technology is fully compatible with both protocol and physical layers, including standard 2.5D packaging processes. This seamless integration enables XPUs to utilize optical interconnects for both compute-to-compute and compute-to-memory fabrics, achieving bandwidths in the tens of terabits per second with nanosecond latencies.

This innovation empowers hyperscalers to enhance the efficiency and cost-effectiveness of AI processing by optimizing the XPUs required for training and inference, while significantly reducing the TCO2 impact. To bolster customer collaborations, Celestial AI is developing a Photonic Fabric ecosystem consisting of tier-1 partnerships that include custom silicon/ASIC design, system integrators, HBM memory, assembly, and packaging suppliers.

About The Role

We are seeking an exceptional Director of Quality and Reliability to lead and scale our Quality and Reliability (Q&R) function across all phases of our technology and product development lifecycle—from early R&D through engineering validation, ramp, and high-volume manufacturing. This is a critical leadership role with broad cross-functional influence, and tasked with building a world-class reliability engineering organization.

The ideal candidate will bring deep technical expertise across silicon reliability, photonics, advanced packaging, and system-level reliability, as well as demonstrated leadership in developing and managing high-performance teams and quality systems at scale. This individual will play a pivotal role in ensuring our products meet the highest standards of reliability and customer satisfaction from concept through end-of-life.

Essential Duties And Responsibilities

• Build and lead a team of reliability and quality engineers capable of supporting complex, multi-disciplinary technology platforms.
• Define and implement a comprehensive Quality Management System (QMS) aligned with industry standards and best practices.
• Drive reliability strategy and execution across the full product lifecycle—from R&D to high-volume production—ensuring design for reliability (DfR), qualification, and ongoing monitoring.
• Establish and track reliability goals, metrics, and KPIs to ensure product performance and customer satisfaction.
• Partner closely with cross-functional teams in engineering, manufacturing, operations, and supply chain to integrate quality and reliability into all aspects of product development and delivery.
• Develop and maintain reliability models, FMEAs, HALT/HASS, accelerated life testing protocols, and failure analysis capabilities.
• Lead root cause investigations and corrective/preventive action programs (CAPA) for quality or reliability issues.
• Stay abreast of industry standards, trends, and best practices to continuously improve Q&R processes and tools.
• Interface with customers and partners to ensure Q&R requirements are met or exceeded.
• Establish and lead the Supplier Quality Assurance (SQA) strategy for all component types—semiconductors, photonic devices, mechanical parts, PCBs, interconnects, and assemblies.
• Define and manage supplier qualification, audit, and monitoring processes to ensure conformance with quality, reliability, and compliance standards.
• Collaborate with supply chain and engineering teams to ensure that supplier materials meet design and performance requirements throughout the product lifecycle.
• Drive continuous improvement initiatives with suppliers, including yield improvement, process capability enhancement, and reduction of field issues.
• Oversee supplier scorecards, incoming inspection protocols, and corrective action programs for non-conforming materials.
  
  

Qualifications

• PhD in Electrical Engineering, Materials Science, Applied Physics, or a related field is strongly preferred.
• 15–20+ years of experience in quality and reliability engineering roles, including 5–10+ years in leadership positions.
• Deep technical knowledge in semiconductor reliability, photonics, advanced packaging, and system-level reliability.
• Proven experience building and scaling Q&R functions in fast-paced technology environments.
• Strong command of industry standards (JEDEC, Telcordia, MIL-STD, etc.), reliability testing, and statistical analysis methods.
• Excellent leadership, communication, and cross-functional collaboration skills.
• Experience working with global supply chains and high-volume manufacturing environments is a plus.
