At R3 you will be at the cutting edge of distributed ledger technology (DLT). 
Corda is a DLT designed for running complex workflows between businesses, without any centralized points of control. You will work on a system trusted by the most demanding industries in the world, including regulated financial markets infrastructure, banks, insurance companies, stock exchanges, payments companies, and others. Corda is designed to be robust, scalable, and high-performance.

Your Team:

  • You will help ensure Corda is the go-to distributed ledger platform.
  • As part of the Corda engineering team, you will design and build capabilities in one or more of the layers of the Corda platform. These range from the base peer-to-peer messaging, inter-node flow engine, distributed ledger, smart contracts, and reference applications. Each offers stimulating, new, design problems and an opportunity to help define the future of distributed ledgers.
  • No team is an island – you will work with many others across the company, to help ensure we build the best possible products. You will have the opportunity to showcase your work and help influence your colleagues’ thinking.

About You:

  • You are a highly motivated, self-sufficient software engineer with excellent system design skills.
  • You have a strong grasp of computer science fundamentals, either through formal study or via some other route. You are curious and quick to learn about new technologies, and keen to build on your skills by learning on the job. You understand distributed systems and have helped build them previously.  
  • We believe the best Engineers can adapt to and learn any language, so whilst we are at heart a Kotlin shop, we welcome anyone with a strong software engineering background who wants to learn. If you have in-depth JVM knowledge, (garbage collection tuning, performance and memory profiling), and/or familiarity with the Java ecosystem that is a bonus.
  • We believe that quality, security, developer experience, and operational experience are everyone’s responsibility, so you will be driven by a passion to ensure excellence in all of these.
  • We’re looking for people who are highly motivated and self-managing. You’ll always think about how to help improve our customers’ experience of our products and services, and will want to influence the thinking of senior stakeholders to make that happen.
  • You have a strong sense of ownership and responsibility. You want to drive delivery whilst maintaining a coherent technical direction.


  • Coding and design, and assisting other Engineers with coding and design.
  • Utilise your subject matter expertise to contribute to development of significant capabilities in R3 products and services.
  • Use comprehensive judgment to make decisions of high complexity and impact, utilising team opinion and support from senior leadership where needed.
  • Use business analysis skills to interact with team product managers to marry technical delivery and client requirements.
  • Use well-developed customer focus skills to anticipate internal/ external customer requests.
  • Contribute to the technical direction and strategic vision of the engineering team.


At R3, we encourage a diverse and inclusive workforce. If you don’t meet all of the above criteria, but you think you’d be a great addition to R3, send us your CV. We’re always interested in meeting collaborative people who are excited to work with us.
