Sr. Principal Data Center Reliability Architect (Fellow)
Location: San Jose , CA (On-site)
Ayar Labs is shattering AI data bottlenecks by moving data at the speed of light. As pioneers of co-packaged optics (CPO), we are using light instead of electricity to move data faster, further, and with a fraction of the energy needed to fuel the explosive growth of AI models.
Backed by industry giants like NVIDIA, AMD, Mediatek and Intel and manufactured in partnership with the world’s leading semiconductor ecosystem, Ayar Labs’ co-packaged optics solution is key to unleashing next-generation AI scale-up architectures.

Strategic Partnerships & Qualification
HyperScaler Collaboration:
- Act as the primary technical lead in partnerships with HyperScaler engineering teams to define "Gold Standard" qualification strategies for optical I/O.
Viability Data Gathering:
- Architect and execute data-collection frameworks that capture long-term performance metrics, proving out the reliability of TeraPHY™ and SuperNova™ technologies under real-world cloud workloads.
Technology Readiness:
- Develop the documentation and statistical proof points required to transition Silicon Photonics from a cutting-edge innovation to a qualified, high-volume product ready for disaggregated compute environments.
Architectural Scope
System Resiliency:
- Define hardware and firmware features for Reliability, Availability, and Serviceability (RAS), ensuring optical chiplets meet or exceed the standards of traditional copper-based silicon.
EIC/PIC Failure Modeling:
- Build predictive models (FIT) that integrate the unique failure modes of Photonic Integrated Circuits—such as laser frequency drift and ring resonator tuning—with standard Electronic Integrated Circuit aging.
Diagnostic Firmware:
- Develop C/C++ diagnostic kernels and real-time health-monitoring tools to identify and mitigate hardware anomalies before they impact system liveness.
Fault Simulation:
- Create automated environments to simulate transient optical noise and hardware-level faults within architectural models and post-silicon lab environments.
Required Skills:
- Master’s or PhD in Electrical Engineering, Physics (Optics/Photonics), or a related field.
- 12+ years of experience in silicon reliability, RAS architecture, or high-speed system validation.
- Working knowledge of Silicon Photonics and its integration with high-speed protocols like CXL and PCIe.
- Proficiency in Python for automation/modeling and C/C++ for low-level hardware diagnostics.
- Proven ability to manage technical relationships with external partners and translate customer requirements into internal architectural specifications.
Preferred Qualifications:
- Familiarity with 2.5D/3D packaging technologies (e.g., CoWoS, SoIC) and their associated reliability challenges.
- Exposure to silicon photonics, laser physics, or optical networking.
- Experience working with major foundries (e.g., TSMC) on advanced silicon integration.
