ASIC Digital Design Verification Engineer

Proto is accelerating the world's transition to an open economy with products that increase access and independence for everyone. We're building Bitkey, a simple and safe self-custody bitcoin wallet that will put customers in control, as well as hardware and software that will help decentralize bitcoin mining and enable new and innovative use cases for bitcoin mining. We're developing these products in the open - you can read more about them at bitkey.build and mining.build. Within Proto, our Bitcoin Products team delivers the product and go-to-market strategy, software, firmware, and custom silicon needed to make Bitkey and our ambitious mining initiatives a reality. Come build the future of money with us!

As an ASIC Digital Design Verification Engineer, you will work closely with other digital designers and physical designers to develop the next generation of mining ASIC. In particular, the challenges of chip/block simulation, emulation and verification are critical parts of this role.

We are a distributed team across the U.S. and Canada, and are hiring for a single remote position.

Key Responsibilities

• Block- and Chip-Level Verification: Develop and execute comprehensive test plans for individual IP blocks and full-chip integrations.
• Gate-Level Simulation & Debug: Run gate-level simulations, analyze netlists, and diagnose timing or logic issues.
• Silicon Bring-Up & Lab Debug: Support bring-up activities in the lab, perform board-level bring-up, and troubleshoot silicon on hardware using oscilloscopes, logic analyzers, etc.
• Automation & Scripting: Create and maintain scripts to streamline verification flows (e.g., regression, coverage collection, and reporting).
• Cross-Functional Collaboration: Work closely with RTL designers, physical design, firmware, and system teams to resolve issues quickly and efficiently.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Computer Engineering, or a related field.
• 5+ years of hands-on experience in digital ASIC verification.
• Strong knowledge of verification methodologies, particularly UVM.
• Proficiency with EDA tools such as Synopsys VCS, Verdi, and waveform viewers.
• Solid experience with gate-level simulation.
• Experience with silicon bring-up and lab tools (oscilloscopes, logic analyzers, etc.).
• Proficiency in scripting languages (Python, Perl, Tcl, Make).
• Strong problem-solving and analytical skills with attention to detail..

Preferred Qualifications

• Master's degree in Electrical or Computer Engineering.
• Familiarity with serial interfaces such as UART
• Experience with common SoC IPs (PLL,GPIO etc)
• SystemVerilog RTL design experience.
• Exposure to full-chip emulation environments (e.g., Synopsys ZeBu).
• Hands-on experience with FPGA prototyping tools (e.g., Xilinx Vivado).
