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.

The Role We are looking for an ASIC Validation Engineer to help bridge the gap between custom mining silicon design and real-world operation. In this highly hands-on, lab-focused role, you'll work closely with ASIC designers and system engineers to debug issues, build test infrastructure, and generate the data needed to enable rapid design iteration and system-level development.

You Will:

Bring up current silicon on

bench platforms, evaluation boards, and system hardware

Debug issues across

ASIC, board, firmware, and system interactions

Develop

bench tests, scripts, and tools

to exercise silicon features and collect data

Build and maintain

test setups

(lab automation, instrumentation, fixtures, scripts)

Partner with ASIC designers to

validate functionality and root-cause failures

Work with system engineers to ensure silicon performs correctly in

target system environments , including mining systems

Generate and analyze data to support

design decisions, characterization, and bring-up

Create lightweight, reusable

test workflows and documentation

for the broader team

Support early manufacturing efforts with

practical validation and debug , as needed

Travel up to 20% to the labs in Oakland, CA or Toronto, Canada

You Have:





Bachelor's degree in Electrical Engineering or related field

4+ years of experience in silicon validation, hardware test, or related roles

Strong hands-on experience in a

lab environment

(bench bring-up, debugging, instrumentation)

Solid understanding of

digital systems and basic analog concepts

Experience writing scripts or tools (Python preferred) for test and data analysis

Comfortable debugging issues that span

multiple layers (ASIC board system)

Clear communication skills and ability to work closely with cross-functional teams

Preferred:

Experience with

ASIC or FPGA bring-up and validation

Familiarity with common interfaces (SPI, I2C, JTAG, UART, etc.)

Experience using lab equipment (oscilloscopes, logic analyzers, power supplies, etc.)

Exposure to

high-performance, power-dense systems

(e.g., mining ASICs, accelerators, or similar)

Experience building

test automation or internal tooling

Familiarity with

data analysis and visualization

Nice to Have

Experience working with

early silicon / first bring-up environments

Exposure to manufacturing test or ATE

Experience working on systems with

tight power, thermal, and performance constraints
