Company mission

To create better tools to help everyone access the economy.

Role

Who you are

  • 8+ years of experience with a significant focus on backend services
  • Worked with various teams to develop software approaches and aligned partner teams to advance the work
  • Navigated architectural decisions that weigh trade-offs between building your own solution or buying something that suits your needs
  • Identified bottlenecks in systems, quantified their impact, and prioritized effectively
  • Bonus: Experience managing infrastructure that spans hardware, mobile, and backend services
  • Bonus: Experience building in a zero-to-one environment where you’ve had to trailblaze your own path

What the job involves

  • 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
  • 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
  • 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

Application process

  • While there is no specific deadline to apply for this role, on average, U.S. open roles are posted for 70 days before being filled by a successful candidate

Otta's take

Sam Franklin headshot

Sam Franklin

CEO of Otta

Block is a financial services technology company comprising of Square, Cash App, Spiral, TIDAL, and TBD. Its biggest brand, Square, offers hardware and software for small to medium-sized businesses enabling them to manage the entire payment lifecycle. It functions similarly to Shopify and Stripe, but has paired online payment processing with physical devices such as registers, payment terminals, and mobile card readers.

The business was originally founded as Square in 2009 by Jack Dorsey of Twitter fame. Already well-established with SMEs all over the globe, Square has significantly benefited from the increased demand for mobile payment systems. Its order management feature remains a go-to tool for small businesses that otherwise didn't have the proper infrastructure in place when demand for home delivery surged.

Square rebranded as Block in December 2021, with the Square brand name remaining in place for their seller business. The company has since come under fire for its security practices, facing lawsuits in relation to a major breach of CashApp user data, and in 2024 announced plans to reduce its workforce in order to cut costs. Despite these setbacks, there is every chance the business will move past this, though it may take some time to rebuild trust in its product.
