About Black Sesame Technologies
Founded in 2016 and listed on the Hong Kong Stock Exchange (HKEX: 2533), Black Sesame Technologies is a leading AI SoC provider. Our mass-produced AI chips are already deployed in the Automotive and Robotics markets, delivering high-performance, automotive-grade compute solutions at scale. As we define our next-generation AI inference accelerators, we are rapidly expanding our new Singapore R&D site. Join us to build the future of intelligent machines from the ground up.
Job Description: ASIC Design Engineer
In this role, you will be part of the core team designing our next-generation AI compute engines. You will go beyond high-level RTL, diving into the fundamental hardware constraints that make high-performance AI silicon possible. You will focus on optimizing high-speed datapath logic while ensuring the design meets rigorous timing and power requirements.
Responsibilities
- RTL Design: Implement high-efficiency logic modules using SystemVerilog/Verilog, focusing on AI-specific ALU and datapath components.
- STA & Timing: Analyze and fix timing violations (Setup/Hold) to ensure the design closes at target frequencies.
- Low Power & PPA: Apply basic low-power techniques (e.g., Clock Gating) and analyze their impact on PPA.
- Design Sign-off: Run Lint, CDC (Clock Domain Crossing), and RDC (Reset Domain Crossing) checks to ensure robust silicon behavior.
- Backend Collaboration: Work closely with the physical design team to understand and resolve congestion and timing issues.
Basic Qualifications
- BS/MS in Electrical Engineering or Computer Engineering.
- Hardware Fundamentals: Deep understanding of CMOS logic, Setup/Hold time, Skew/Jitter, and the impact of PVT (Process, Voltage, Temperature) corners.
- STA Knowledge: Familiar with the concept of Static Timing Analysis, including path delays, false paths, and multi-cycle paths.
- HDL Proficiency: Strong coding skills in SystemVerilog/Verilog with an emphasis on synthesizeable code and hardware-oriented thinking.
- Digital Architecture: Understanding of pipelining, stalling, and bypass logic in high-performance datapaths.
- Scripting: Proficiency in Python, Shell, or TCL (essential for EDA tool interaction).
You would be a “Star Candidate” if you have:
- ASIC Flow Experience: Familiarity with the industry-standard ASIC design flow (from RTL to GDSII).
- ALU/Math Foundations: Knowledge of computer arithmetic (Fixed-point, IEEE-754) and its hardware implementation.
- Advanced CDC: Experience handling complex asynchronous interfaces and synchronization techniques.
- RISC-V Exposure: Understanding of RISC-V ISA and its pipeline stages.
