Pros
Excellent 401K match, long term stock incentives, good office space.
Cons
The mRNA Center of Excellence is run by toxic Translate Bio management and employees brought over from the acquisition. They have a "good ol' boys club" where they bully and harass other employees with impunity because they protect each other, from upper management all the way down. The only thing that matters is "were/are you a TBIO employee, and for how long?", the longer you worked for TBIO the more you are protected from consequences and promoted via nepotism rather than merit. Managers punch down on talent, throw reports under the bus, and office politics are valued over science. Management is also aware of employee burnout problems caused by 50-70 hour work weeks, but does nothing to fix it and instead doubles down, oh and they don't reward the effort either.
