RTL Engineer

About the role

Design the RTL that defines our AI accelerator. You'll architect and implement the digital blocks — compute datapath, memory subsystem, on-chip interconnect, and control logic — from microarchitecture spec through synthesis-ready, timing-clean RTL, and own those blocks end-to-end with architecture, DV, physical design, and DFT all the way to silicon.

What You'll Do:

• Own RTL design of digital blocks/subsystems for our accelerator — microarchitecture definition, SystemVerilog implementation, and integration
• Translate architectural specs into efficient, synthesizable RTL that meets power/performance/area (PPA) targets
• Drive microarchitecture trade-offs — pipelining, datapath vs. control, clock/power gating — for high-performance, low-power design
• Partner with DV on verification, PD on synthesis/timing/floorplan closure, and DFT on testability
• Own block-level quality: synthesis, timing/constraints (SDC, STA), lint, and CDC signoff
• Contribute to architecture definition and design reviews; debug across simulation, emulation, and post-silicon bring-up
• Use and develop AI-assisted tool flows to accelerate design and verification

What We're Looking For

• Strong digital-design fundamentals and expert Verilog/SystemVerilog RTL
• 5+ years designing complex digital blocks/SoCs taken to silicon
• Solid microarchitecture skills — pipelining, datapath/control, FIFOs, arbitration, memory subsystems, on-chip interconnect/NoC
• Synthesis & timing awareness — writing synthesizable RTL, SDC constraints, STA, clock/power gating, CDC, lint
• Demonstrated collaboration with DV, PD, and DFT across the full RTL2GDS flow to tapeout
• Scripting (Python/Tcl/) for design automation
• (Optional) AI/ML accelerator or high-performance compute-datapath design; low-power techniques (UPF); high-speed interfaces (HBM, PCIe, SerDes); advanced nodes (7nm or better); RISC-V/CPU design; FPGA prototyping

Compensation

Final offers depend on level, location, and skills relevant to the role. Additional compensation: equity grant per company guidelines; medical / dental / vision; 401(k); standard PTO. 

Visa Sponsorship
