Hi there, we are looking for a Redmine pro who can set up plugins, work with deployment scripts, ensure AWS is properly backing up code and not over charging us, configure SMTP and mail receivers, develop build scripts, debug broken plugins and write custom script for new features. Work is intermittent, we have 3 Redmine websites we care for and we're looking for one more person to add to the team and address issues as they come up. This is a telecommute gig, you need to already be used to running Skype on a daily basis. Your timezone should match up as much as possible with ours [Pacific to Eastern USA]. While we don't expect you to fix issues immediately when flagged, we do expect to hear from you when you can get to issues we flag and to make a general effort to address issues, especially any urgent ones that appear, within a reasonable time frame appropriate for the severity of the issue. You should be experienced enough that you know how to set up, optimize AWS and can recommend proactive enchantments for security, performance and workflow without needing to get such direction. For redmine you should be comfortable quoting and working on bending and molding redmine to fit client needs. Thanks!
