Avantages
Can't recommend any aspect of employment with RedZone. The employees are all good people and wonderful coworkers, but are so unsupported in their roles that the net effect is deeply negative for everyone involved.
Inconvénients
As other reviews have noted, the founder and current CEO is the root cause of RedZone's various dysfunctions. A partial list of those would include:
* Base pay is generally below industry standard, and the difference is NOT offset by other, non-monetary compensation. That's not to say there is no other compensation--it just isn't a worthwhile tradeoff.
* Employee reviews are irregular (if they happen at all), and actual performance is neither recognized nor rewarded. Cost of living adjustments are said to be yearly and automatic, but only seem to happen if you hound the CEO about it, sometimes for months (or years!)
* Support for professional development is nonexistent. This is true both for external opportunities (conference travel, for example) and in terms of your actual work keeping you aligned with industry peers.
* The CEO makes decisions reactively and emotionally, without consulting (or, often, informing) even his senior management team. He frequently makes promises to current and prospective clients without regard for how they may impact existing plans--even those he personally initiated or signed off on.
* Overall, the CEO seems to have startlingly little understanding of software development or data management. An example: he is always seeking to cut corners, but with no apparent sense of how much risk any specific cut might represent; he would have more hesitation deploying an unpolished UI than an incomplete and untested authentication service.
* For what it represents itself as capable of, the company is woefully understaffed. This is noticeable both as each current employee being overtasked, and as the absence of what should be key roles within the company. For instance, despite selling products built atop complex, custom data models, the company has no data engineers, no one with a data science or modeling background, and no role with bottom-line responsibility for data quality.
I could go on, but the most important thing to understand if you are considering working for RedZone is this: while it is unlikely you will be treated unpleasantly at any given moment, and may really like your coworkers, you will be systematically unsupported and pressured to work in ways that trend inexorably to cynicism and burnout. That will slowly sap your sense of self-worth, until it feels impossible that you could get a job elsewhere. It's really, really not worth it.
