System Administration


2013-07-12 20:31


Do you like grappling with scale and performance problems? Would you like to use your skills to bring open data to the opaque world of multinational corporations? Would you like to work in a small and fast-growing startup environment that thrives on busting siloed data for public benefit and business insights? If so, OpenCorporates’ new SysAdmin role could be for you.

OpenCorporates is a big data platform. Our Debian-based infrastructure currently spans 23 servers, including replicated data stores (MySQL, Redis), a graph database (neo4j), clustered search indexes (solr), and production and staging environments for our application software (Rails 3). Over the next 12 months, we are expecting to increase the quantity of data stored and served by several orders of magnitude.

You will take responsibility for the robustness, performance and security of our infrastructure.

Activities include:

  • improving our monitoring, management and provisioning systems
  • proactively identifying infrastructure bottlenecks so we can scale smoothly
  • design and implement a security policy
  • support developers in developing continuous integration practices

You should have several years experience in a similar, data-focused environment. Skills should include:

  • Several years extensive experience of Debian environments
  • Proven expertise in managing performance and stability of J2EE webapps
  • Expertise in nginx, MySQL essential
  • Expertise in redis, Solr, neo4j an advantage

Following an initial intensive period of benchmarking and improving the infrastructure, we expect the role to be part time. For candidates who wish to work full time, we may have opportunities in other areas of the business, such as software development or community management.

Alternatively, it may be possible to achieve our goals with a 4 month contract of intensive analysis, setup and documentation, for subsequent handover to other technical staff. We're open to ideas on how best to handle it.

The role would ideally be based at our offices at the Open Data Institute in London. However, what's most important is talent and a commitment to what OpenCorporates is doing, and remote working may be considered for exceptional candidates. Applicants must have a valid UK work permit. Strictly no recruitment agencies, please.
