ASIC Lead - Proto

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!

With Proto, we're building hardware and software that will help decentralize bitcoin mining, promote new and innovative use cases for bitcoin mining, and drive a major new business for Block. As the ASIC Lead, you'll lead a talented team focused on development of a core component of our mining products: the custom silicon that powers both the mining rigs we're building as well as customer-developed systems for new mining applications. Top-performing silicon is critical to our customers' success. Power efficiency (energy expended for a given hashrate), area efficiency (hashrate output for a given silicon area), and system uptime directly impact mining profitability for operators of all sizes. Our ASIC team's work is foundational to these metrics and to our Proto business, and we're looking for the right leader to develop the team and product into a market-leading position.

As ASIC Lead, you will:

• Build, grow, and develop the best mining silicon team in the world – and then take on the bullet points below with and through your team
• Lead the end-to-end development process of high-performance mining ASICs, from defining architecture to custom physical design to verification and post-tapeout productionization
• Identify, understand, and apply new technologies to deliver performance not previously seen in the mining industry
• Work with the hardware system team to co-design our chip and system for maximum overall performance, including not just power and area efficiency but also best-in-class uptime and reliability
• Collaborate with the hardware operations team to deliver effectively and predictably at scale, including fostering relationships with key partners to ensure access to key technologies and capacity
• Cultivate strong, trusting relationship with 3rd party IP and EDA vendors, engineering service providers, OSATs and fabrication houses
• Communicate clearly, directly, and with empathy at all levels of the organization

You have:

• 15+ years of experience in silicon development from concept to mass production
• Demonstrated success in leading and managing teams of at least tens of engineers to repeatedly ship custom silicon in high volume (having led geographically-dispersed teams across multiple time zones is a plus)
• Experience working in a small company and/or early stage initiative
• Experience with advanced technology nodes (at least 3nm)
• A deep appreciation for technical excellence in your and your team's work
• An inspiring and contagious sense of urgency in your work and leadership
