Pros
Burns and Mac has enjoyed a very highly performing ESOP, particularly over the past 20 years, and as such has produced very good retirement balances for long term employees. The ESOP is really a benefit for very long term employees however, so don't count on it being all that great if you plan to leave within 6-10 years. Also, past performance is no guarantee of future performance, so be aware that the ESOP likely won't always be as good as it is currently. During my tenure, year end bonuses were very good. But beware, this does come at the expense of lower than average base salaries (this has been validated by many former BMcD employees). Bonuses are also not guaranteed, and are typically given out at the end of the year, so there's a definite "carrot on the stick" feeling to them. Finally, many talented engineers work at BMcD. You'll likely be apart of a team with many competent and driven individuals.
Cons
Nepotism is common. Managers always seem to select one or two individuals who receive nearly all of the best mentorship and opportunity. Moreover, this is not always determined by competence. In my department, many different types of engineers work together, and all play a vital role. Amongst the engineers, it is widely known that if you aren't a specific type of engineer, do not expect to be promoted to any sort of management role. My advice - be very honest with yourself regarding your professional development track, and leave for better opportunities if the opportunities are not in your future. The longer you stay in a dead end role, the more you handicap your long term development. Overwork is the norm. Nearly everyone I worked with was overworked to one degree or another. Certain engineering roles were given very little additional support. Additional staff were hired only when absolutely necessary. I worked many weekends, and quite a few 15+ hour days. Some managers will let you charge overtime, and others will strongly discourage it. If your project is out of budget, it is expected that you work on your own time until the design is finished. Company culture is traditional and un-yielding. Company dress code sits somewhere between the upper end of business casual, and business formal. If you are a man, don't expect to grow your hair out, show tattoos, etc. (regardless of if you see clients or not). I can't speak for the policy towards women. Very egocentric. By and large, Burns and Mac considers itself the greatest engineering company on the planet. Anyone that quits is quickly dismissed and bad-mouthed by management after their departure. The general sentiment expressed by management is that you should feel lucky to work for such an amazing company, regardless of how much you are overworked and underappreciated. Overall I believe BMcD can be a great place to work for the right type of person, who happens to fall into the right position within the company, but in my experience this wasn't common. I believe that most of the accolades that BMcD has received over the past 10 years are largely exaggerated, and not nearly as deserved as management would like to believe. I had high hopes for working at BMcD, and was overall disappointed with my experiences there.
