London, GB
Job Purpose:
 
R3 is an enterprise blockchain software firm working with a broad ecosystem of more than 300 members and partners across multiple industries from both the private and public sectors to develop on Corda, our open-source blockchain platform, and Corda Enterprise, a commercial version for enterprise usage.
Our global team of over 200 professionals in 13 countries is supported by over 2,000 technology, financial, and legal experts drawn from our global member base.
 
The Corda platform is already being used in industries from financial services to healthcare, shipping, insurance and more. It records, manages, executes institutions’ financial agreements in perfect synchrony with their peers, creating a world of frictionless commerce.
We are looking for a Security Research Engineer to join an amazing group of technologists to contribute to Corda, Corda Enterprise and other products in the Corda ecosystem. The role will revolve around securing the Corda platform, by undertaking vulnerability assessments, conducting research and contributing to all stages of the secure development life-cycle. This will require collaborating with the engineering team to understand the development process, and supporting development using threat modelling, architecture and design.
 
You will have a history of conducting application vulnerability assessments and will be able to clearly communicate your findings through report writing and close collaboration with the engineering team. Ideally you will have some knowledge of the secure development life-cycle and software engineering principles. You can work independently to research a problem domain to gain insight and subsequently deliver the work and solve the problem. You will be comfortable getting into the guts of a complex distributed system and be able to conceptualise its operation at many levels. Most importantly you are excited and motivated by the challenge of solving hard problems in a way that delivers to clients and delights them.

·        You'll need excellent communication skills, both verbal and written. You'll be happy presenting to the company at all-hands meetings or explaining the impact of vulnerabilities you identity to a range of stakeholders.
