Senior Engineer, Site Reliability

LearnUpon is looking for a Senior Engineer, Site Reliability to join our team in Dublin. This is a flex role, working 1 day per week from LearnUpon's Dublin office.

LearnUpon LMS helps organizations train their employees, customers, and members. Businesses can manage, track, and achieve their unique learning goals — all through a single, powerful solution.

With offices in Dublin (our HQ), Belgrade, Philadelphia, Salt Lake City and Sydney, we are a global team with lots of diverse cultures, backgrounds, and experiences that puts our customers' experience at the heart of everything we do. Our culture fosters an open, collaborative and supportive environment where our accomplishments are celebrated and encouraged. We're always striving for the best solution (not the easy one).

About the team:
