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 and 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 and Singapore. Our vibrant and centrally located offices are filled with collaborative spaces, healthy (and some not so healthy!) snacks and state of the art work spaces and equipment. 
We are looking for a talented SQL DBA who is motivated by achievement, loves working in a close-knit team, wants to be trusted to use and develop their skills, to learn without limits, and 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, and 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.
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 and reliable operation of R3’s databases in Production, Testing, Staging and QA Environments plus any associated toolsets. You will seek to ensure that the uptime, performance, availability and security of those environments and associated database resources is maintained to industry standards – 99.999% availability, SOC2 compliant etc. You will work alongside, and support our Development, Security Ops and 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 and hitting deadlines are all paramount to enjoying life at R3.
