What We Look For

We are looking for smart people who are able to work quickly with highly skilled peers. Our team is small and distributed but very high functioning. We need people who can self-start and solve problems on their own. They also need to collaborate with both internal and community stakeholders, while being an engaged team member in all stages of the development process as we work towards a shared vision. They need to participate in the requirements review and give valuable feedback to the business.

A Quick Overview (Database Administrator)

We are looking for a DBA who can contribute to and examine a design for a large-scale database with replication/sharding and implement this design. The candidate should be able to manage day-to-day operations of multiple databases across multiple environments (Development, Staging and Production) and the workflows between them. The role involves working with multiple engineering teams and understanding their software and technical architecture in order to optimise their workflows/integration with databases.

The ideal candidate will have Postgres experience (both DevOps and Management) but other SQL experience is still desirable.

We are looking for somebody who is more than the traditional DBA that can only write huge, long-running queries, or who only speaks SQL and can’t handle related technologies such as REDIS and GraphQL. We are interested in candidates who are open to something new and are keen to be responsible for the deployment of the server, as well as its use.

You will be part of a talented software engineering team working on new, highly scalable products and services. There will be opportunity to reveal your creative side as well, on the unfathomably large applicability of a global public blockchain.
