Ready to put all those ideas about scalability into practice in a situation where you really need it? We're helping Stack Overflow and other sites that you've probably heard of serve billions of ads per month. At that scale, things get very interesting.
As an engineer at Adzerk, you'll have the opportunity to work on all parts of our system, from the front-end web UI to the engines that serve the ads. Our system uses Node.js, C# (Mono), ASP.NET MVC, jQuery, MongoDB, Hadoop, and RabbitMQ.
We're also looking for someone to fill a more devops-oriented role. We use Chef to administer our systems on AWS, build and deploy using Travis-CI, and monitor using DataDog (a pretty cool startup based around statsd).
Performance and scalability are our two primary concerns, and with the traffic and growth rates that we're experiencing, lots of the lessons that you've learned start to break down. Because of that, it's not as important what you know right now – what matters is how quickly you can learn and adapt.
