Opening/hiring bot

[mochet]

Importance

• An upcoming release will introduce 3 new working groups, meaning the activity of hirings + openings will likely increase. Future releases will add even more working groups, I believe we'll probably have something like 10 WGs in total (or around that number)
• We currently have no automated way to announce new openings, review periods and hiring outcomes
• We also have no way automated way to annouce firings
• Depending on how JOYtasks is implemented, there may be heavy utilization of openings, far beyond what they currently experience

Options (we should pick one option):

• We have a #hiring-bot channel that covers all of the activity for ALL working groups in one channel
• We have a #hiring-bot channel AND a #lead-hiring-bot channel. #hiring-bot would only include announcements relevant to the hiring of individual workers, and the #lead-hiring-bot channel would include announcements relevant to the hiring of new leads
• Each WG gets a bot for its specific channel which announces information relevant to that WG in particular (we could still also have a channel that announces ALL hiring/opening events)

Implementation

• If an opening is created, the bot should announce this with key information such as WG, title, description, deadlines, stake requirements, creator
• If an opening is changed to "review" stage, this should be announced, including a summary of how many people applied
• If someone is hired from an opening, this should be announced
