Senior Software Engineer

Bitkey sits within the Proto team. Proto's purpose is to accelerate the world’s transition to a more open economy by making products that increase access and independence for everyone. The first two initiatives we’ve identified that represent the biggest impact to this purpose are in the Bitcoin space with Bitcoin mining and Bitkey, a self custody Bitcoin wallet. While we’re starting there, we don’t believe the need for tools to increase one’s independence is limited to bitcoin or the financial space. One principle across everything we do in Proto is open development – show and tell. We develop products in the open, you can read more about them at bitkey.build and mining.build.

Building an entire product from scratch required hiring a team of senior engineers who could navigate the early days of defining the product requirements while also having an experience across a myriad of domains. These include important foundational items such as infrastructure and DevOps as these are essential to helping establish early architecture in a greenfield project.

Now that we’ve shipped the first version of our product, the team would like to have a deeper and dedicated focus on this work so that we can improve the overall experience for a growing team of engineers, and help them focus on building the product instead of fighting fires constantly. This person will sit closely with our product teams as their primary customer to help define the roadmap for our ongoing infrastructure. This role requires heavy collaboration with all of our disciplines including mobile, server, web, firmware, and security and will be critical to improving the success of our engineers and overall product.

You Will:

• Build out and maintain a continuous delivery pipeline for Bitkey applications, including the deployment and promotion story for ECS and Lambdas
• Help secure our infrastructure that handles the customer key we custody and work with the security lead to drive continued security enhancements on our platform for internal and external customers
• Manage node infrastructure that communicates with the blockchain and allows customers to move funds
• Maintain a high quality bar for our overall infrastructure by ensuring we have the right visibility into tracing, metrics, logging, and alerting
• Iterate on our staging and production infrastructure deployment story
• Continue evolving our testing infrastructure in different environments from hardware to mobile to server side for both our own services and the bitcoin network.
• Work with Block foundational and security teams to leverage foundational tooling and coordinate cross-BU infrastructure work
