Are you a Principal Software Engineer who is ready for a new challenge that will launch your career to the next level?

  • Tired of being treated like a company drone?
  • Tired of promised adventures during the hiring phase, then dropped off on a remote contract and never seen or heard from the mothership again?
  • Our engineers were certainly tired of the same.

At GliaCell our slogan is “We make It happen”.

  • We will immerse you in the latest technologies.
  • We will develop and support your own personalized training program to continue your individual growth.
  • We will provide you with work that matters with our mission focused customers, and surround you with a family of brilliant engineers.

Culture isn’t something you need to talk about…if it just exists.

If this sounds interesting to you, then we’d like to have a discussion regarding your next adventure! If you want to be a drone, this isn’t the place for you.
