About Celestial AI

As the industry strives to meet the demands of the AI workloads, bottlenecks in data transfers between processors and memory have hindered progress. The Photonic Fabric based Memory Fabric provides an optically scalable solution to the ‘Memory Wall’ problem, enabling tens of Terabytes of memory capacity at full HBM bandwidths with low tens of nanoseconds of latency and extremely low power. The Photonic Fabric based Compute Fabric enables Terabyte class bandwidth between compute nodes at low latency and power. Photonic Fabric delivers a transformative leap in AI system performance, ten years more advanced than existing technologies.

Job Description:

As an HLS design engineer, you will contribute to the core processor functionality that helps enable Celestials unique value proposition. You will collaborate with architects and a small team of design engineers to implement the specified algorithms and control structures using HLS, while simultaneously making performance, power, area and latency optimizations. Using the fast iteration times enabled by HLS you will often evaluate a range of possible implementations before choosing the best suited version.

ESSENTIAL DUTIES AND RESPONSIBILITIES:

• Implement functionality as specified in the Celestial architecture simulator in HLS (System C/C++). Negotiate changes with architects as needed to meet performance goals.
• Author detailed design documents.
• Perform power, area, and performance trade-off analysis.
• Collaborate with the DV team and review test plans to ensure bug free designs.
• Drive coverage closure of your designs.

QUALIFICATIONS:

• 5+ years of RTL design experience (Verilog, SystemVerilog, digital microarchitecture).
• Extensive experience coding C/C++.
• Experience with High Level Synthesis for ASICs or FPGAs.
• Knowledge of basic processor architecture.
• Experience with full ASIC design cycle (spec through bring-up) preferred.
• BS plus 7 years relevant experience. MS preferred.
