Senior Systems Administrator

** We are offering only full-time opportunities at this moment. You will be joining as a Partner, the highest title offered at this firm. By submitting your resume, you agree to keep all interview questions confidential, so as to give other candidates an equal chance. **

There’s something incredibly liberating about being a sysadmin at Domeyard. We love technology and aspire to automate everything. We don’t sell a product; we don’t really need customers; and we don’t have a marketing team. We benchmark performance by the nanosecond. We measure “market share” by the number of servers we own. Our vision is to set new thresholds for modern computing.

Domeyard is an electronic trading startup based in Boston. We are backed by the founders of one of the largest hedge funds in the world ($55 billion in AUM) and pioneers behind one of the largest public internet companies in Asia. Our operating capital has grown 6x in the past year. We’re looking for an experienced systems administrator/engineer to join our engineering team.
