What I Do Working at a start up, I do a lot of different roles from manufacturing engineering and program management to finance and business operations. There's even some IT thrown into the mix! I work closely with outside contract vendors since we are small and do not have all our capabilities in our company of 25 people. It is a fast paced company but very fun! Before that I worked at a much bigger company (5000+ people) in different roles for 14 years.
