Pros
Although they are growing fairly quickly, Aviture does a great job maintaining a close-knit, but welcoming culture; which has been carefully cultivated to always encourage the cross-pollination of knowledge and expertise across all developers, designers, and business development teams alike. Frequent outings and other in-house activities, such as lightning talks, small group sessions, Friday lunches, and a bi-weekly all-hands meeting keep everyone engaged and provide opportunities for employees to spend time together regardless of what project they are primarily working on.
If you are looking for a place where you can be a butt in a seat converting coffee into code without having to step outside your comfort zone, I probably wouldn't recommend Aviture. While building a given solution for a client, Aviture looks to craft a vision beyond what the client has requested. Whether that includes new solutions to other problems the client has, new directions the solution could be taken in, or simply educating the client's developers about coding practices and architecture, Aviture is always looking to make a lasting impact beyond delivering a single solution.
One of the things I enjoy most about being part of a consulting firm is that there are few projects with which Aviture has a long-term attachment to (i.e. - primarily maintenance & support work). Because of this, I've been able to work on 7 or 8 projects in my 3 years here, all using a wide array of languages, frameworks, etc, providing me with countless opportunities to learn and expand outside of my comfort zone.
Cons
Mentorship is somewhat of a fledgling idea among many of the teams, and your first couple months may feel like a trial by fire. This is something being actively worked on, but it does still have a way to go.
