The excellence in every Watchfire sign begins with our outstanding engineering team designing a quality product. In production, we choose quality over expedience or expense.

Job Description:

This senior level Software Engineer position will be part of the software engineering team, helping build the next generation of our flagship software product for the digital signage industry. A person at this level will research, design and develop software products within a specific technical project. S/he can provide solutions for designs and development plans of high complexity which typically requires a broad background of technical and process knowledge. This position provides expert guidance, drives decision making and supports the Software Engineering group in various technical and functional aspects of research and development of new products.

A successful candidate will be a strong team player who is able to work across multiple functions and disciplines. The candidate should be self-directed and have experience and knowledge of software design, coding, and testing methodologies. Though the focus for this position will be on designing and developing embedded systems running on micro-controllers, there will be opportunities to work on user facing web and mobile applications.

Our product software is a critical differentiator in our market, and we take great pride in our in-house products developed entirely by this team, from embedded systems to exceptional user facing GUI applications.
