Pros
Wonderful co-workers and amazing pragmatic management. The 3 founders are very approachable and really care about their employees. The whole company takes being the best software engineering company in the Philadelphia area very seriously and the consistent use of good practices like test driven design, pair-programming, and agile management really reflect that. The pay and benefits are great. Working at Prompworks is the most productive and sustainable job I've ever had. Also, it's a great place to consistently improve your skills if you really care about being a top-tier software engineer.
Kontras
While the office space is lovely, modern, filled with natural light, and in a great location, the bathrooms are in the older separate part of the building and are dark, old, and very stuffy.
