Blockchain is the world's leading software platform for digital assets. Offering the largest production blockchain platform in the world, we share the passion to code, create, and ultimately build an open, accessible and fair financial future, one piece of software at a time.

We are looking for a Senior Site Reliability Engineer to join our engineering team as we tackle some some of the most interesting problems in the crypto space, like how do we securely scale a distributed financial platform that touches millions of people a day.

Site Reliability Engineering (SRE) and DevOps, is an engineering discipline that combines software and systems engineering to build and run large-scale, distributed, fault-tolerant systems. SRE ensures that Blockchain’s services are reliable and available meeting our users' and the business's needs, and delivers a fast rate of improvement while keeping an ever-watchful eye on capacity and performance.

At Blockchain, SRE is also a mindset and a set of engineering approaches to running better production systems—we build our own creative engineering solutions to operations problems. SREs are responsible for the big picture of how our systems are designed for operability, how they relate to each other, and we use a breadth of tools and approaches to solve a broad spectrum of problems. Practices such as limiting time spent on operational work, blameless postmortems and proactive identification of potential outages factor into iterative improvement that is key to both product quality and interesting and dynamic day-to-day work.
