Since we're all media companies now--thank you, social networks--we need to make career transitions with the same aplomb that a startup makes a pivot. Luckily Leslie Bradshaw, who's transitioned from data visualization firm JESS3  to video startup Guide , has walked the personal-press-conference path before. 
These are the steps that worked for her:
Though it might be tempting to be all "come hither" with your tweets and updates, the risk outweighs your attention-seeking reward--as Bradshaw writes, "any swarm of new friends or connections would have surely tipped my hand early," so abstain from mass friending of your soon-to-come office playmates.
The launch sequence is the when, what, and where of your announcement. Remember when LeBron James announced that he was "taking his talents"  to Miami? This is like that, but without you looking like a gigantic jerk. Bradshaw breaks it down:
- When: To own your message, time it down to the minute.
- What: Figure out your talking points.
- Where: Twitter, Facebook, and LinkedIn are obvious updates--but get SlideShare, AngelList, and any smaller networks, too.
Leaving some breathing room between announcing your departure and celebrating your new job is respectful to all parties involved--Bradshaw put seven weeks between announcements.
The keys to writing a gracious goodbye:
Show gratitude: Focus on what you're going to miss the most.
Stay positive: Never go negative--if you can't muster positivity, Bradshaw says to keep it short, sweet, and inoffensive.
Share timing: Say when you'll follow up an update with your new job.
The subsequent "I've got a new job!" post will rhyme with this one, showing how thankful and enthused you are for the new position.
Bradshaw recommends listening to the 1812 Overture  for an extra dose of epic as you fill in your new title across platforms.
The "outpouring of positivity" Bradshaw received after announcing her new job "was the greatest feeling in the world." You want that, too. Now you know how to get it.
