We have a large, high-trafficked social media platform that uses WordPress as a backend CMS. The site is a Pinterest-like system that displays a lot of photos. The entire site at this stage has over 14K user accounts with ~150K-200K photos. It is all hosted on an AWS x-large instance with LAMP stack. We are looking for an engineer that can provide ongoing support and optimisation for us as the site grows and also to perform fixes and add new features when needed. Ongoing tasks would include server maintenance and monitoring, setting up caching, database optimization, load balancing, all on AWS infrastructure. We would also need some feature updates from time to time so the person will also need to know WordPress development. (working with Themes, Plugins, PHP, HTML, JS, MySql). Experience in running and maintaining large scale platforms preferred. Experience with WordPress required. The candidate should be responsive via emails and other chat mechanisms to tend to outages.
