My favorite Language Engineering event of the year is LangDev.
They just started the CfP. This year I am going to help reviewing proposals.
It will be held in Mainz at the end of April (27 and 28).
Incidentally the 27th is my birthday 
More info available on http://langdevcon.org/
Oh this would be amazing to go to, but I don’t think I would be able to travel out of the country by then (american laws on traveling are getting weird). I’m already going to PyCon in april tho! It’s the one in Pittsburgh. I’ll definitely try to see if I can attend langdevcon next time!
Sounds very interesting. I’m planning to come. Do you know are there archives of presentation packages of the previous meetups?
BTW, funny coincidence but April 27th is my birthday also. We can share a birthday cake at the meetup
I like the idea is cake sharing! Unfortunately I am not sure if the videos. I have a recap of LangDev 2018 here: https://tomassetti.me/langdev-2018/
Just registered for the conference a minute ago. It is only 1 hour traveling time for me. 
I’ll see if I can go - some family related stuff is in the way, but who knows
