Pros
Interesting work. Ok pay. Ok benefits. [Compared to Seattle tech companies.]
Kontras
Don't join F5 in America. The CEO is optimizing his spreadsheet. If you are dev/test in India or support in Mexico, you have a great future. Everyone else should be nervous. Over 50 should be very nervous. Recent layoffs included rock stars that would have been great assets in cloud migration. This "pivot" is really about cutting expenses and impressing Wall Street in the short term. The new C-suite ignores (or is ignorant of) the fact that intelligent, high-level networking on hardware and in cloud are substantially the same. Inexpensive new employees will not be able to backfill the lost experience of the recent layoff for years. Core markets (majority of profit) are being put at risk. Ciena's annual layoff (CEO's last company) has come to F5. CEO asked for employee commitment but has not committed to employees.
