We are seeking an experienced and dynamic Senior Software Engineer to join Conclave, R3’s new privacy-preserving platform. 
R3’s Conclave team is on a mission to build the leading privacy-preserving platform for the development of tamper-proof software. Applications range from aggregating sensitive data to detect sophisticated types of fraud, training AI models with sensitive data sets, or aggregating sensitive transaction data for risk reporting across organizations. 
Conclave is a software development kit leveraging Intel SGX technology, evolving to a suite of complementary cloud services, rooted in hardware-based confidential computing techniques, designed to bring privacy-preserving capabilities to developers globally. 
As a senior software engineer, you will be responsible for the design (which includes API design) and development of the existing core SDK. You will be required to understand Intel SGX and other key components to improve and grow the product.
Conclave is an early-stage and technical confidential computing product so you will therefore need to be someone with a passion for and deep understanding of privacy-enhancing techniques. 


  • Work as part of a team within the larger engineering group to deliver high quality and well tested code
  • Design elements of a larger software application, then present these designs to lead engineer and application architect
  • Evaluate trade-offs between different implementation and technology choices
  • Mentor junior developers to become industry-leading engineers
  • Assist in estimating and scheduling complex engineering tasks
  • Code review peers both within your team and in the wider organisation
  • Liaise with the Release Manager to package and deliver software, while ensuring it meets complex security requirements such as deterministic builds


  • Strong understanding of computer science and engineering principles, most likely obtained through a combination of advanced academic study and significant professional experience
  • A strong Java background and understanding of the JVM ecosystem
  • C++ experience would be a significant advantage
  • Good understanding of API design
  • Experience working with open requirements and limited guidance, identifying goals for yourself and bringing them to management to approve rather than having direction set for you.
  • Proven problem-solving skills and ability to work under pressure
  • Proven experience leading small teams of engineers


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.
