Senior Software Engineer

MAD is looking for a full-time Senior Software Engineer to join our team.

Primary Function

The successful candidate will assume primary responsibility for managing the back end of our platform as usage scales up to tens of thousands of elevators.

Our small software unit operates very much like a start-up except that we’re inside an established company. We tend to have rapidly shifting priorities as we navigate the just-in-time nature of building a critical health-and-safety platform for several large customers.

In terms of operational maturity, we believe in addressing pains as they arise because there isn’t enough time to implement everything we could dream up. As such, many of our operations are still manual or underdeveloped but we work towards increasing maturity as we grow. There is huge potential here for the successful candidate to flourish in many competencies (back end, databases, IT/dev ops, test automation, networking, security, IoT, etc.)

Our emergency communication system enables elevator monitoring stations to see inside elevators during emergencies and enables multi-modal communication to accommodate passengers who may be seeing or hearing impaired.
