R3 is a financial innovation firm that leads a consortium partnership with over 100 of the world's leading financial institutions. We work together to design & deliver advanced distributed ledger technologies to the global financial markets.
R3 has employees based in over 11 (and counting!) countries across the globe, with our headquarters in London, alongside office locations in New York City & Singapore. Our vibrant & centrally located offices are filled with collaborative spaces, healthy (and some not so healthy!) snacks & state of the art work spaces & equipment. 

We are looking for a talented DevOps engineer who is motivated by achievement, loves working in a close-knit team, wants to be trusted to use & develop their skills, to learn without limits, & be at the forefront of a true technology revolution.

Ideally, you would have come from a start-up/small firm where you need to be good at everything, & excellent at some things. You'll be used to working in a small team where social interaction is as high as the work rate. You'll go the extra mile for the person sitting next to you as you know they would do exactly the same thing for you. You'll be used to having the freedom to make decisions without too much oversight - but at the same time you'll own the responsibility to get things right. You like hoarding story points; you don't necessarily want to share a Jira. You probably spend some time at home working on your own projects - having a decent gaming rig would be normal - as would be making sure that you don't have any high CVSS vulnerabilities. And finally - you've started looking at blockchain & realised how powerful it is, how it's going to change the future & how you really need to start working for the industry leader - R3.

Still reading? Good. Let's dive into the detail as that's where you feel most comfortable (as do the rest of us here). You'll be responsible for the upkeep, configuration & reliable operation of R3's Production, Testing, Staging & QA Environments plus any associated toolsets, such as DataDog, PagerDuty etc. You will seek to ensure that the uptime, performance, availability & security of those environments & associated resources is maintained to industry standards - 99.999% availability, SOC2 compliant etc. You will work alongside, & support our Customers, the Business, Development, Security Ops & other Technical teams within R3 - therefore being a team player, having a great personality, a sense of humour, being able to work under pressure, being empathetic towards different cultures, communicating effectively & hitting deadlines are all paramount to enjoying life at R3.
