About OneTick

OneMarketData LLC (‘OMD’) is a US company with a global customer base and globally distributed remote workforce. We’re best known for ‘OneTick’, the world’s most powerful tick analytics platform. We’re also a major supplier of market data for research and trading, and our regulatory products are used by the world’s largest exchange group, the world’s largest market-maker, the world’s largest options trader, and by regulators, banks, and brokerage firms around the world. We’re an agile company with a staff of 200, strongly oriented toward software engineering and DevOps. We use a modern Cloud-based technology stack. See for more information.


Our Implementation and Operations team helps to implement, deploy, monitor and maintain our standard product offerings in our AWS hosted environment and in Customer’s environments to deliver high quality solutions.  We’re looking for disciplined, highly motivated engineers able to work on challenging projects for national regulators, central banks, and quantitative hedge funds. You’ll interact on a daily basis with OMD colleagues and with customers.  Most projects are in a Cloud environment, and we expect Kubernetes to be increasingly important. Some projects will require a security clearance and GDPR processor agreement.
