Senior Software Engineer (Backend)

Senior Software Engineer



As a Senior Software Engineer, you are an expert at developing software solutions from start to finish.  You must be able to work independently, be creative with your solutions and think on your feet.

You will serve as an in-house expert, both for managers from other departments who need software solutions and the less experienced staff within the Engineering department. You will also be responsible for keeping the project on track, documenting everything and keeping proprietary information confidential.

You should definitely be the type of person that appreciates diversity in your day, and challenges outside of your comfort level!
