About the role
Ready to put all those ideas about scalability into practice in a situation where you really need it? We’re helping StackOverflow , reddit , and other sites that you’ve probably heard of serve over a billion ads per day… and that number is growing very fast. Adzerk engineers are responsible for working on all parts of the system. This includes the front-end web application, back-end services, and the ad delivery engines. Our platform is built using Node.js with Coffeescript, Clojure, Mono, JQuery, MongoDB, and Hadoop, with a whole lot of AWS and Chef. We’re currently serving over 25,000 req/sec (and growing fast), so you’ll get to work on some real scalability challenges. 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. Things you should be interested in -- or even better, have experience with: Clojure Large-scale distributed systems HTML, CSS, JavaScript Bonus points for startup experience! Things you should know about us: We have an engineering-driven culture, and our CEO is a software developer. We have no professional managers — everyone contributes. Your work will have an immediate and profound impact on our product and business. We ship code dozens of times a week. You will have the freedom and responsibility for choosing what tools and libraries we use. You will have a direct role in building the team, helping us choose additional team members as we grow in size. We use the open source model internally to manage our work. We submit pull requests, and other engineers review them before merging. We prize open source, and do our best to contribute back to the community. Everyone gets equity. We want a team of partners. We all have unlimited vacation. We work hard, but at a sustainable pace. We all have a flexible work schedule, and we have the option to work at home part-time. When applying, please include as many of the following as possible: A link to your GitHub account. A brief description of your skills, passions, and how you like to work. A link to your blog and/or other things you’ve built. We’re looking for awesome engineers with five or more years of experience and a four-year degree in Computer Science or equivalent experience. You must be eligible to work in the United States and willing to work in Adzerk's Durham, NC office.
