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, evolving to a suite of complementary cloud services, rooted in hardware-based confidential computing techniques, designed to bring privacy-preserving capabilities to developers globally. Conclave Cloud is a serverless platform for privacy-protecting services. It allows developers to write applications where data is always processed inside enclaves that provably protect the data from attackers, including the hosting provider and the developers themselves. Conclave Cloud is ideally suited to solving multi-party collaboration and privacy problems but can also be used to add an additional layer of protection of all data processing applications.
Conclave’s mission is to make it ridiculously easy for all developers to create privacy preserving applications. The product differentiates itself on developer experience and the ability of our customers to write applications in high-level languages and have them hosted without having to understand the details of the underlying hardware trusted execution environments or worry about maintaining servers or scaling services.
To enable us to expand on our cloud vision, we are looking for a software engineer who can develop secure, efficient web services, integrating with our Conclave privacy-preserving technology. To be effective in the role, it will be necessary to learn how to effectively use cryptography to protect data. A knowledge of cryptography or even Confidential Computing technologies such as Intel SGX would be useful but could be learnt as part of the role.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.
