Pros
Exciting environment with almost full in-house manufacturing. Able to work with device-level software (C, RTOS embedded software), and Windows .NET WPF framework for desktop-only software. Little to no corporate bureaucracy, so ideas become projects which become tangible products and software in as little as 1 - 3 months. If you love science and chemistry this is the place for you. Work hours are very reasonable and only occasional late night work and overtime required for important projects.
Cons
As a smaller company, requirements change fast, so it can be frustrating to have a feature removed/added at the last second. Also, time tables are very liquid and some projects can be put on hold at the drop of a hat or become a last-second priority with no warning.
