Pros
I have been working at Flatiron for over a year. As noted in other reviews, the people that work here are incredibly smart with degrees from the best schools in the country and work experience from other major tech providers. The environment is very challenging. You are constantly pressed to find solutions to difficult problems within tight frames but our mission -- serving cancer patients and customers by improving treatment and accelerating research -- requires this level of intensity. Our leaders definitely "walk the walk" and are committed to ensuring that employees understand the mission and how individual contributions work towards it. The company is constantly providing opportunities to learn and teach on a variety of topics related to Oncology. Every week there are knowledge sessions where we have an oncologist or data scientist or outside expert give a lecture on key topics related to our work. If you like to "teach", there are always opportunities to get in front of the group and present a relevant topic. Flatiron also offers a shadow program where employees can "shadow" an oncologist to better understand how our products/software impacts our customers and patients. As also mentioned, the office space is great as are the perks. Food, beverages, social activities, charitable events, all keep employees engaged and working hard. There is always a buzz of activity and opportunities to collaborate with fellow employees. Net/net -- if you like a start-up environment and working at a company with a mission of saving lives, you will find Flatiron to be a very rewarding experience.
Cons
Culture and intensity are not for everyone. Successful people at Flatiron are willing to run with an issue without having to be told exactly how to approach something. Nothing is spoon fed so if you are looking for a formal training program as part of your on-boarding, this may not be the company for you. You also have to be able to deal with uncertainty around work load and job descriptions. Some weeks you may be working in one area only to have to pivot and work on another "fire" If you don't like this, you probably won't be successful working here. Growth of company may be considered a con for some. It is tough to get to know everyone that is coming on-board given the large numbers of new hires. You have to go out of your way to meet with folks and not be shy about setting up meetings and introducing yourself to fellow employees.
