Java/Blockchain Developer - London (Hybrid working) - 6 month initial contract - Inside IR35

I am currently partnering with a Global financial services client who are seeking a Java Developer who has experience working with Blockchain. This will be an initial 6 month contract and will be a hybrid role split between their London office and remote working.

Responsibilities will include:

* Design the architecture, data models, and flows for CBDC-related experimentation
* Develop test cases, prepare testing environments, and document the findings to guide business and technical decisions
* Develop CBDC experiments from a technical standpoint and lead the development of novel feature implementation
* Assess the capabilities and limitations of technology vendors, and, where appropriate, evaluate the benefits and drawbacks of DLT or non-DLT technology
* Stay current with technology advancements in the CBDC space and identify technologies that can contribute to strategic goals and provide business value, including suggestions for roadmaps where appropriate
* Utilize a range of proven languages such as Java, Python, and JavaScript on Unix-like virtual machines to build solutions that drive value for customers and stakeholders

Technical Skills & Core Competencies:

* Experience in implementing enterprise-level DLT/blockchain systems/protocols including R3 Corda and Ethereum-based networks such as Quorum and Hyperledger Besu
* Experience writing smart contracts in Solidity and Kotlin, using the web3 library, Truffle Suite, or OpenZeppelin
* Strong development experience using cloud infrastructure with preference for AWS, but Azure and GCP are nice to have
* Experience implementing authorisation/authentication flows or working against existing services that rely on OIDC/SAML/OAuth2
* Experience designing and implementing microservices architecture, container-based APIs using container frameworks
* Experience with several programming languages, frameworks, and design patterns (examples include Java, Python, C/C++, Unix shell scripting, Spring Boot, JavaScript, React, Node, Express, RESTful APIs, and GraphQL)

This role has been classified as being Inside IR35 and candidates will therefore need to be happy to work via an umbrella company.
