Pros
Conductor's a fairly large startup now, but during my time three and a half years there it felt small in the best kinds of ways: The executives were accessible; my coworkers were approachable; the organization was transparent. It's a meritocratic place to work -- good ideas and hard work are executed and rewarded. Most managerial positions are filled through internal promotions.Coworkers tend to be cordial and collaborative. There are vanishingly few divas in the Engineering organization. Those that exist generally temper themselves to the team's ethos or work themselves out of the organization on a short time horizon. Four months out and in a new job I love, I still miss my coworkers at Conductor daily. They were supportive, hard working, and bright, easily the best part of the position. You can learn a lot here if you're willing to pursue it, particularly if you're willing to get $&*# done in a maintainable way.
Cons
Work/life balance is at times difficult at Conductor, although I'm not convinced that was always management's fault (full disclosure: I was a low-level engineering manager for a couple years at Conductor). Like most technology firms, there's a lot to do and not nearly enough engineers to do it. For the most part, deadlines are reasonable, but no one's going to explicitly stop you if you indulge your workaholism and burn yourself out, until you're so far gone it's obvious to everyone. If you work for Conductor, you'll need to practice economy of motion. Conductor struggled with project management and prioritization for most of my time there, but a few key hires and new positions in 2016 dramatically improved the situation by the time I left. Projects felt much more defined and executable in 2016 than at any point before, and that trend looked both healthy and established.
