I found my current position through the whoishiring post in November 2015. Payment is monthly, just invoice at the end of the month for hours worked in the month x hourly rate and payment is made via direct deposit 2 weeks later. During the month we track daily using Jira for our clients and weekly using an internal tool to track what hours we worked for each client so the clients get billed accordingly. Hours are reported based on the honor system, so as long as they are reasonable nobody questions them.

Since our model is to assign engineers, designers, and project managers to various clients, some of the workflow depends on the clients' needs but so far 4 clients have followed the same pattern: daily scrum with one of our project managers, our engineers, and any of the client's team members, weekly project summary, and periodic updates to any budget estimates. As far as scheduling, our company only provides US and Canada based workers so in theory timezones aren't that big of a problem.

If you have any questions or want to work with us, my info is in my profile.
