Blockchain DevOps Engineer


    Blockchain technology is poised to become the next big computing paradigm, disrupting existing processes and unlocking new business models through secure multi-party computation.   In a rapidly evolving digital economy, blockchain technology will form the backbone of the next era of distributed enterprise and consumer applications with its business value surging to exceed $3.1 trillion by 2030 per Gartner.  Businesses are looking to understand and apply the distributed ledger technology that started with Bitcoin to streamline and innovate their business problems.


    This position is located at the Rakuten Blockchain Lab in Belfast city centre. We have grown an engineering team of 10 during the first year of operation and have multiple active blockchain projects due for production launch in the next 3-6 months.  The existing team collectively has many years of experience in building secure, high availability enterprise platforms for financial services, health and consumer electronics sectors.  We will be growing the team to 20 over the next 12 months and as a result are now actively seeking a passionate and motivated DevOps Engineer.  

    This is the first dedicated DevOps focused role in the team and the successful candidate will work as an integral part of our multi-disciplinary team.  You will be focused on delivering high quality enterprise-class blockchain-based solutions and platforms and get a chance to work on the emerging blockchain frameworks, learning from the experienced blockchain engineers in the team.  You will be responsible for deploying, automating, maintaining, troubleshooting and improving the systems that keep the backend infrastructure running smoothly. The role requires you to have hands-on technical experience and a can-do approach towards environment automation / management and continuous improvement.


    In the Rakuten Blockchain Lab, we take ownership of the full end-to-end solution from inception through to production and beyond. Our services are built in Node.js with various relational databases and follow a micro-services architecture.  We work with multiple public and private blockchain protocols & frameworks depending on the requirements. We package our services with Docker and use Google Kubernetes for automating deployment, scaling and management of these containers in both public and private cloud environments. We value short feedback loops and have implemented a CI/CD pipeline as well as automated unit, integration and acceptance tests.


    This is an exciting opportunity for an individual who has gone beyond the previously defined Developer or Sys Admin roles and who take a more holistic view of their technical environments.  You will be driven by the desire to improve the overall software delivery process including configuration management, infrastructure provisioning, continuous integration and delivery, monitoring & health to name but a few.  You will likely be a developer who got interested in deployment and network operations, or a sysadmin who has a passion for scripting and coding.  You need to be able to work in a collaborative manner with colleagues across multiple office locations on different time zones.


    • Deploying, automating, maintaining and managing cloud based test and production infrastructure, to ensure the availability, performance, scalability and security of our systems.
    • Build, release and configuration management of test and production infrastructure code.
    • System troubleshooting and problem solving across platform and application domains.
    • Proposing architecture improvements, recommending process improvements.
    • Evaluating new technology options and vendor products.
    • Ensuring critical system security using best in class cloud security solutions.
    • Assist project and product leaders in making risk-managed planning and release decisions



    • 3+ years working in a DevOps role or in either a Linux System Administrator or Software Engineering role
    • Experience of provisioning and managing cloud infrastructure (e.g. Azure, AWS, GCE)
    • Experience in designing application infrastructure with respect to High Availability, Scalability, Security and Monitoring
    • Proficiency in one or more scripting languages (e.g. Python, Bash, Perl)
    • Experience of using/administering tools to automate the testing, promotion, and deployment of infrastructure (e.g. Puppet, Chef)
    • Experience of using/administering tools to manage continuous integration builds and delivery pipelines (e.g. Jenkins, Travis)
    • Experience of using/administering configuration management systems (e.g. Git, Subversion, CVS)
    • Experience with using/administering system monitoring tools (e.g. Nagios).
    • Experience of working with Containers (e.g. Docker) & Container Orchestration (e.g. Kubernetes)
    • Ability to analyze and resolve complex infrastructure resource and application deployment issues.

    • Experience of working with Micro-service based architectures
    • Knowledge of API Management solutions (e.g. Kong)
    • Prior experience of working with high availability, secure enterprise platforms in the financial services sector

    You don’t need to have direct experience of working with blockchains, but you will need to be able to demonstrate an interest in new and emerging technologies and be eager to take on new challenges.
