Pros
Market leading product that is a no-brainer for anyone using the cloud, A player colleagues who are always willing to help, competitive pay, experienced exec team that care deeply about the business and employees. If you work hard and apply yourself you will be given the opportunities that you want to progress your career quicker than you could elsewhere - growing from the inside is big here. CloudHealth jump-started my career and the experience gained working with the senior management teams here is priceless - it has been an MBA in itself. The Boston HQ and EMEA HQ in London are extremely nice and located as central as one could possibly want.
Cons
Honestly can't think of anything that would qualify as a negative here. This is such a great, truly global company and if you're thinking of applying my advice would be to not hesitate.
