What people at Appian say
Reviews originally posted on Glassdoor.
Even as a relatively junior engineer, your voice is heard. Contributions feel recognized, and compensation is excellent. Those in the engineering department are a pleasure to work with, and the department is still small enough that you can have an observable, measurable impact on the end product.
I think the work environment at Appian is one of the best I've been in. Everyone is competent and helpful, the work is interesting, and the compensation is great. Appian is the first company I've worked for post-graduation and it's definitely better than any place I've interned at. Management seems very on top of things and I trust that this company is going places.
The people you work with have an incredible impact on your work experience. The people at Appian are what make it a fantastic place to work.
The best part about working at Appian is being part of such an incredible, fun, welcoming, and supportive culture. There are tons of opportunities to get involved and have an impact, even as a new employee. The environment is extremely collaborative, giving everyone the opportunity to work, learn, and succeed together. The people at Appian are genuinely some of the most kind and competent individuals I have ever met. I am consistently impressed with how willing everyone is to drop what they are working on to help others. On top of that, there are tons of opportunities for growth at Appian and the company is invested in YOUR ability to learn. Other fun perks (some specific to Engineering) include free breakfast every Monday, flexible dress code, designated work hours set aside for personal learning/improvement and working on independent projects, great office snacks, and flexible working hours. I genuinely look forward to going to work every day at Appian! :)
An amazing culture of learning and opportunities for professional development
