About Us

NS1’s mission is to manage the world’s application traffic. We are the market leader in DNS and traffic management software and services, and our customers include the biggest properties and largest enterprises on the internet, such as Salesforce, LinkedIn, Squarespace, Pandora, Imgur, Yelp, Dropbox, and many more. Our modern DNS technologies enable optimized application delivery, couple via our APIs into the tooling and processes of today’s DevOps organizations, and deliver reliability and performance at global scale. We operate a worldwide, highly tuned Managed DNS network, and also deliver our technologies to customers as single-tenant software deployments. We solve incredibly challenging problems on behalf of our customers, in the most mission critical parts of their stack.

The Role

NS1 is bringing data science to modern application traffic steering and traffic management. Our ideal candidates will be comfortable with (and excited about) taking on greenfield projects on a small but growing team. You should be capable of articulating the core problem statement, generating your own hypotheses, testing ideas independently and communicating your findings to a team of stakeholders including engineers. We value simplicity and efficiency, always starting with a first approximation before choosing more complex methods. The data sets are internet-scale (true big data). As such, ideal candidates are familiar with distributed computing frameworks and the unique challenges that arise with developing and deploying analytics at scale (streaming analytics, Bayesian inference, machine learning, etc).
