About the Position

Contrast is looking for a talented back-end server-side engineer to join our team developing instrumentation agents for NodeJS, specifically supporting ExpressJS, Sails, Koa and HapiJS frameworks. This team works with the internals of NodeJS and does not building web applications. It's not a front-end or full-stack position. You would be joining the larger “agents organization”, which includes engineers working in Ruby, Java, PHP, Perl, GoLang, .NET, and Python.

Writing instrumentation agents is a responsibility we take very seriously at Contrast. An instrumentation agent is a module that profiles code and performs monkey patching and/or duck punching of code in the runtime.

Our customers trust us enough to run our agents directly in their applications. We're looking for an engineer to exercise that power carefully, to help us build a quality, thoroughly tested agent that our customers run with complete confidence.

An ideal candidate has advanced experience with server side JavaScript (NodeJS). He or she likely has professional C experience, including some experience contributing to open source frameworks and/or libraries, this could be a great opportunity for you to deepen your understanding of NodeJS' unique characteristics. You like to reverse engineer code, making it better with each iteration.

Please include a link to your Github or BitBucket account, as well as any links to some of your projects if available.
