Judging from things Steve Yegge has written about Amazon, and from friends of mine who have worked there, I don't get the impression that Amazon is a company dedicated to technical excellence. In particular I seem to recall something about 40 million lines of C++ code in their core product, and about mediocre engineering talent and high levels of burnout due to the technical debt they're required to deal with... In fact, ever-increasing engineering costs would be just as indicative of mounting technical debt as it would of an increasing commitment to R&D. |
On the other hand, when you're in the trenches of a product team at Amazon, good engineering takes a back seat to features, deadlines, and keeping everything running. There was an incredible amount of pressure from the top to maintain high levels of service, but not a lot of support for taking the time to refactor or rework those systems to address the underlying causes of service disruption. Everything was always an emergency, but we always had to make the shallow fixes.
Overall, I'm much happier at Google where there is a lot of support for good engineering at all levels of the organization, not just as a means to an end, but as an end in itself.
