Pros
Very good pay, performance based bonuses, telecom allowance or business phone, company vehicle or vehicle allowance for remote employees, company credit card for business related expenses. If you feel underappreciated and work hard at your current position, this is a place that allows you to stand out. Workaholics will thrive here. Generous PTO, management actively encourages PTO use, it's not discouraged to take week-long PTO several times per year, at least in my work group. While work is mostly independent, asking questions, curiosity, and assistance is readily available. If you are MT or MLS looking for employment outside of the lab, I would seriously consider Sysmex.
Cons
With each product, there are a few key employees who have the majority of knowledge and experience. If you have questions that only these people have answers to, they are always very busy and it can time some time to hear back. Promotion inside a work group can be a slow process, if advancement is important to you, look for advancement opportunities outside of your work group. In-house employees work typical 9AM-5PM central time schedules, if you are remote and need help from someone at HQ outside of these hours you'll be waiting until they either come in for the day or until the next morning; not a big deal if you are on central time but can be problematic if you are working on the east or west coast.
