About the role

10x is seeking SREs to join its highest-impact, largest-scale, site reliability teams in London and Sydney.

This is a great opportunity for a SRE to join the team and own and drive the vision for the service going forward. We are looking for SREs who are passionate about working with cutting-edge technologies, bring deep technical knowledge and experience.

Site Reliability Engineering (SRE) is an engineering discipline that combines software and systems engineering to build and run large-scale, massively distributed, fault-tolerant systems. SRE ensures that 10x’s services - both our internally critical and our externally-visible systems - have reliability and uptime appropriate to users' needs and a fast rate of improvement while keeping an ever-watchful eye on capacity and performance.

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. Much of our software development focuses on optimising existing systems, building infrastructure and eliminating work through automation. As SREs are responsible for the big picture of how our systems relate to each other, 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.

SRE's culture of diversity, intellectual curiosity, problem solving and openness is key to its success. Our organisation brings together people with a wide variety of backgrounds, experiences and perspectives. We encourage them to collaborate, think big and take risks in a blame-free environment. We promote self-direction to work on meaningful projects, while we also strive to create an environment that provides the support and mentorship needed to learn and grow.
