Job description

Responsibilities

About the team:
Our team is building industry-leading, highly efficient, and scalable video codec hardware solutions (FPGA and ASIC) from the ground up to better serve billions of users. We are looking for strong video codec design engineers to design hardware accelerators for advanced video encoding and processing. The successful candidate will be part of a fast-growing team that includes algorithm, architecture, software, firmware, and hardware design and verification experts with a dedication to technical excellence and a passion to build large-scale and high-performing video platforms and services.

• - Verification Planning: Deeply analyze architecture and design specifications to develop comprehensive and high-coverage module-level, subsystem-level, or SoC system-level Test Plans.


• - Environment Development: Build from scratch or maintain highly reusable and automated advanced verification environments (Testbench) and components (Scoreboard, Monitor, Sequence, etc.) based on UVM methodology.


• -Test Execution & Closure: Develop high-quality testcases, execute Constrained Random and Directed tests, and drive Functional and Code Coverage to 100% closure.


• -System-Level Verification: Responsible for Gate-Level Simulation (GLS) and SDF back-annotated timing simulation. Assist in FPGA prototyping and Hardware/Software co-debugging on Emulation platforms (e.g., Palladium/ZeBu).


• - Flow Optimization: Develop and maintain regression testing scripts and automation tools to continuously improve the team's overall verification efficiency and compute resource utilization.

Qualifications

Minimum Qualifications:

• - Bachelor's degree or higher in Microelectronics, Computer Science, Electronic Communications, or a related field.


• - 3+ years of working experience in ASIC/SoC verification.


• - Mastery of SystemVerilog and UVM methodology, with the ability to independently build IP-level or SoC-level verification environments.


• - Proficiency in mainstream simulation and debugging tools (VCS/Incisive/Questa, Verdi, etc.).


• - Exceptional debugging and logical analysis skills; proficient in Python/Perl/Shell scripting for automation.

Preferred Qualifications:

• - Familiarity with the architecture, protocols, and complex data flows of core SoC subsystems (e.g., CPU/NPU clusters, Memory subsystems, NoC).


• - Hands-on experience with Hardware Emulation (Palladium, ZeBu) or FPGA prototyping platforms.


• - Proficiency in Formal Verification methodologies and tools (e.g., JasperGold).


• - Experience in SoC-level Performance and Power-Aware (PA) verification.
