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. 

The Software Engineer is responsible for contributing to the development of the R3 software stack and associated service. They will be a hands-on software engineer, able to work well at all levels of the stack: systems engineering, distributed systems design and development, through to financial modelling.
The successful candidate will have a successful track record of delivering complex software projects and be able to point to experience of establishing sound software development processes and tooling.  They will be experienced in multiple languages and multiple development methodologies and will have delivered both traditional applications and solutions, delivered as a service. They are likely to have worked in both banking and startup environments and be comfortable with ambiguity.  They will likely be active in one or more open source projects, have experience working in geographically distributed teams and have a sound understanding of security engineering principles. Capital Markets and/or Trading technology experience is not mandatory, but a plus.
