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.

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 a highly motivated and detail-oriented Silicon Photonics Process Engineer to join our photonics team developing photonic technologies for next-generation Datacenter scale-up network solutions. In this key role you will based in our Singapore office working with our external foundry partner in Asia as the primary interface between foundry and design team in the US, helping develop and manufacture Celestial silicon photonics products.
Essential Duties And Responsibilities

• Foundry on-site technical expert in silicon photonics to assist and oversee silicon photonics foundry process development.
• Provide on-site support to resolve silicon photonics design and integration issues in coordination with the internal design team and externally foundry process team.
• Work closely with foundry to define, develop and manage process development plans.
• Document process capabilities, design rules, and other design-for-manufacturing (DFM) guidance in collaboration with foundry and internal stakeholders.
• Help define, oversee and track process qualification plans.
• Manage photonics wafer fabrication lots from tape-out through delivery, ensuring quality and timeliness.
• Track and communicate lot status, issues, and risks with internal stakeholders.
  

Qualifications

• MSc or Ph.D. in Electrical Engineering, Physics, Materials Science or related field.
• 5-10 years of experience in silicon photonics design and/or photonics process integration.
• Strong background in integrated silicon photonics design and manufacturing.
• Experience working with silicon photonics foundries, including hands-on experience with process documentation and familiarity with tape-out procedures.
• Strong problem-solving skills and the ability to work independently in a fast-paced environment.
• Excellent communication and collaboration skills.
  

Preferred Qualifications

• Experience with new silicon photonics process development and technology transfers.
• Hands-on experience with layout tools (E.g. Cadence Virtuoso, OptoCompiler)
• Experience with data analysis tools and scripting (e.g. JMP, Python) for analysis of test data.
  

LOCATION : Singapore*

• This role will be based in our Singapore office, offering an exciting opportunity to work in one of Asia’s most dynamic business hubs. While the position is located in Singapore, we welcome applications from qualified global candidates who are open to a 2–3 year expatriate assignment. Relocation support will be provided for the right individual, along with the chance to gain international experience and contribute to our global team in a fast-paced, collaborative environment.
  

We offer great benefits (health, vision, dental and life insurance), collaborative and continuous learning work environment, where you will get a chance to work with smart and dedicated people engaged in developing the next generation architecture for high performance computing.
Celestial AI Inc. is proud to be an equal opportunity workplace and is an affirmative action employer.
